Oddly, in the audio books Autobots' Lightning Strike and Autobots Fight Back, Ravage is referred to as a hound.
The stealthy, shadowy Ravage operates best alone. A creature of the night, Ravage performs most of his actions in the darkness, both literally and figuratively — there are times when he will cloak himself in such shadow and subterfuge that not even his fellow Decepticons know where he is or what he's doing ... but since whatever he's up to is sure to be bad news for the Autobots, they don't really mind. Ravage is aloof, but his craftiness and deadliness mean that his actions command respect from his comrades.
Not in possession of a conventional humanoid form, Ravage's robot mode resembles an Earth jaguar. He is capable of masking himself from many forms of detection: he walks without a sound, becomes virtually invisible in subdued light or shadow, and he can shield his internal electromagnetic radiation from monitoring devices. Superior sensors in his nose module give him highly advanced senses of smell, hearing and electromagnetic wave detection, and he is armed with two low-radiation one-megaton proton bombs mounted on his rear hips. Ravage's greatest weakness is the light - in addition to robbing him of his invisibility powers, he is simply particularly sensitive to it, and can be blinded by especially bright bursts.
Like the other Decepticon cassettes ("Cassettrons" in Japan), Ravage is connected to Soundwave, although the strength of this link varies from continuity to continuity, appearing at its strongest in the original animated series. Although presented by the toy line to be a microcassette, the fiction presented Ravage's alternate mode as a standard-sized cassette.
Although never fully explored, it is safe to assume that Ravage, along with his other fellow cassette tapes share some sort of close bond to Soundwave, whether this be as a leader or as a parental-type figure. Whatever the relationship is, the cassettes must coexist with Soundwave for both protection and possibly regeneration, after all they stand more chance of survival housed in his compartment than on their own due to sheer size and power output. As Soundwave's loyalties ultimately rest with Megatron, the cassettes follow suit, obeying their leader's orders without question. Ravage would most likely come to Soundwave's defense or protection in battle, much like a dog and its owner, and portrayals in various continuities would show him to be almost fanatically loyal to Megatron.
In the episode "More Than Meets The Eye Part 1", upon the Transformers' awakening on Earth in 1984, Ravage was first deployed to dissuade humans from investigating a Decepticon attack on a power plant. Later, when Soundwave infiltrated the Autobots' headquarters, Ravage inserted himself into Teletraan I's cassette drive in order to access data on natural resources which Soundwave recorded, but while Soundwave escaped, Ravage was captured by the Autobots and later used in an attempt to tricking Megatron into a trap. Autobots Hound and Mirage spoke loudly of a nearby rocket base and the fuel it housed, deliberately allowing Ravage to overhear them and purposefully dropping the key to the cage he was held in so that he might escape and pass the information on to Megatron, allowing the Autobots to ambush him. Ravage acted according to plan, reporting to Megatron (this being the strange instance in which he appeared to speak, as he relayed information in a voice belonging to no other character from his cassette mode), but Megatron realized the trick at work, and successfully fooled the Autobots and acquired the energy required.
Ravage was frequently deployed on hunting and spying missions throughout the Transformers' adventures on Earth, often pitted against the small Autobot, Bumblebee and the Autobots' human allies — opponents that his comparatively small size did not prevent him from engaging. Occasionally, he even tussled with Optimus Prime and Skyfire, but such fights rarely lasted.
Among Ravage's most notable misadventures were his time-traveling in "A Decepticon Raider in King Arthur's Court" to medieval England alongside Starscream, Ramjet and Rumble, and his displacement in "Child's Play" to an alien world populated by giants, where a regular housecat hunted him down like a mouse. He also, at one point, ended up battling a real jaguar, defeating it with the aid of his rockets.
Ravage was among the Decepticons who attacked Autobot City in the Earth year 2005, disabling an Autobot communications array alongside Rumble, Frenzy and Ratbat, then battling their Autobot cassette counterparts. In 2006, the episode "Call of the Primitives", Ravage was among the "Primitive" Transformers amassed by the ex-assistant of the ancient genius, Primacron in order to combat his energy-draining creation Tornedron. Alongside Ratbat, Steeljaw and Ramhorn, Ravage was defeated and had his energy drained by Tornedron in the form of a tiger, but was later restored when Grimlock defeated the monster.
Ravage was one of Megatron's closest allies as he began the Autobot/Decepticon war, and accompanied him in his attack on the Autobot spacecraft, the Ark, which resulted in Megatron and Optimus Prime's forces being entombed on Earth in stasis for four million years. When the Transformers then awakened in 1984, Ravage used his stealth powers to survey a nuclear power plant, and had a series of encounters with the naive Autobot Mirage, who appealed to Ravage to stop fighting and work together with the Autobots so that they might return to Cybertron. When Ravage severed Mirage's arm with his jaws, Mirage saw the light and defeated Ravage.
Across the Atlantic, the United Kingdom's exclusive Transformers series (which interspliced its own original stories with reprinted American strips) briefly shone the spotlight on Ravage when he and Windcharger were forced to team up to shut down the Ark's malfunctioning computer, AUNTIE. He also put in an appearance in the 1985 UK Transformers annual where he and the Insecticons attacked a meeting between the Autobots and Ronald Reagan, being defeated when he was accidentally hit by one of Bombshell's cerebro shells. Then, back in the U.S. title, during a period in which the Decepticons had allied themselves with the human Donny Finkleberg, the Autobots staged an attack on their base, and Finkleberg fled and fell in with the Autobot, Skids, only to be pursued by Ravage. Skids led him to an abandoned mining town, where, after a battle, Ravage was tricked into falling down a mineshaft.
Rendered inactive by the fall, this was all that both the U.K. and U.S. comics would see of Ravage for quite some time. The U.K. comics were first to depict his return when a rift in space and time threatened the destruction of Earth and Cybertron. The tremors that ripped through the planet as a result of this jarred Ravage back online, and he soon discovered the base of the time-traveling future Decepticon, Galvatron, in the cave system he had fallen into. Siding with Galvatron initially, Ravage battled the Autobot Wreckers and the Decepticon Mayhem Attack Squad alongside Galvatron, a clone of Megatron (believed by all to be the real article) and Galvatron's fellow time-traveler, Scourge, who was convinced by Springer that he, Galvatron and their deceased companion Cyclonus needed to return to the future to stop the rift. As the situation deteriorated, Ravage realized that this was the truth, and aided Scourge by presenting Shockwave — driven to madness by the illogical nature of events — with the most logical argument for helping accomplish this.
With reality saved, Ravage accompanied the Megatron clone back to Cybertron, where they were attacked by the real Megatron. At a loss due to his senses' inability to tell the difference between the two, Ravage watched the scene play out as the real Megatron convinced the clone to destroy itself to prevent the personality of its creator, Lord Straxus, buried within it, from taking over.
With Megatron's subsequent apparent destruction battling the Autobot medic Ratchet, the stage was sent for Ravage's return in the U.S. comic. Returning to Earth, Ravage joined up with Shockwave again, who established a small cell of Decepticons to depose the current Earth-based Decepticon leader, Scorponok. The battle was interrupted by the arrival of the Neo-Knights, and all the combatants' subsequent transportation to Cybertron by Primus to battle Unicron. He was last seen battling against Unicron.
Ravage's played a minor role in Dreamwave Productions' 21st century reimagining of the animated 80s cartoon universe. In the course of publication, the company introduced a new Cybertronian body for him — a bipedal, clawed semi-humanoid form. This body was meant to be a bestial version of the robot modes used by Rumble and Frenzy. Transformers: The Ultimate Guide, by Simon Furman threw mystery on his origin, revealing that there is no record of his creation. It also notes that he was one of the first Transformers in this continuity to possess a beast mode.
Ravage was recruited as a Decepticon under the leadership of Megatron in his war against the Autobots on the planet Cybertron. He worked under communications officer Soundwave. When a new Autobot leader, Optimus Prime, was chosen, Ravage was sent along with the Insecticons and Soundwave, to attempt to kill him and bring the Matrix to Megatron, but they failed, forcing Megatron to confront Optimus personally.
Later, after Megatron's disappearance, Ravage stayed with the Decepticons under Shockwave.
Ravage was chosen as a member of the crew of the Nemesis when Megatron launched it to attack the Ark, an Autobot ship. Both ships fought, and after the Decepticons boarded the Ark, it crashed on the planet Earth, where all on board were placed in emergency stasis lock for millions of years. In the Earth year 1984, a volcanic explosion awakened the Ark and it's computer, Teletran One, reformatted all on board to be able to assume the forms of Earth machines. Ravage was given a robotic form resembling an Earth jaguar and the alternate form of a cassette tape.
Eventually, the combined forces of the Autobots on Earth and their human allies were able to capture the Decepticons. A ship called the Ark II was built to take the Cybertronians back to Cybertron, along with some human companions, but the ship exploded shortly after takeoff. The human allies were killed, but the Cybertronians were lost in the ocean, again in stasis lock.
Ravage was among the Transformers who briefly fell under the control of the terrorist, Lazarus. Bumblebee, Frenzy, Grimlock, Laserbeak, Prowl, Ravage, Soundwave and Starscream were forced at attack the Smitco oil refinery in the Arctic to display their power for sale to the highest bidder. Ravage would only appear once more, being activated by Soundwave in order to hunt down a mysterious intruder, but was deactivated instead by the intruder — who turned out to be Starscream.
Despite Ravage's death, he would go on to make an appearance of sorts in the second crossover. When a team of G.I Joes trying to fix a space-time tear arrived in a nightmare future where Shockwave had conquered Earth, they were surrounded by a number of drones clearly based on the original Ravage. These were dispatched by Ratchet.
Ravage made his first chronological appearance in the main IDW Publishing continuity in issue #2 of The Transformers: Megatron Origin, where he, Laserbeak and Buzzsaw were shown to be already working with Soundwave, unlike Rumble and Frenzy. Accompanying Soundwave to a clandestine meeting with Megatron, leader of the underground gladiator games. When they realized Autobots had tracked them, Laserbeak and Buzzsaw took out one while Ravage dealt with the other. He is shown briefly in issue 3 on Ratbat's viewscreen sabotaging an industrial plant.
His next chronological appearance was in a Spotlight issue on Soundwave. Here, he was once again serving under Soundwave, being used by him to tail Bludgeon's facsimiles to Bomb-Burst. Once Soundwave realized their true intentions — to reanimate Thunderwing — Soundwave and the cassettes attempted to stop him, with Ravage attacking Iguanus, leading to his being run through by Bludgeon's energy sword. With the explosion of Bludgeon's charges detonating Mount St. Helens. Like his Marvel incarnation, Ravage was capable of speech. The final issue of The Transformers: Escalation revealed he had been revived, but was now a prisoner of the human defense organization Skywatch. In the follow-up series The Transformers: Devastation Ravage (with his higher functions shut down) was shown being used by Skywatch to track the other Transformers on Earth. Soundwave, still trapped in cassette mode, used his own signals to throw off Skywatch's control, calling Ravage to free him.
Following the end of the Great War, when the Decepticons finally met their defeat at the hands of the Autobots, some of Megatron's army were granted amnesty and were reformatted along with the majority of the other Transformers on the planet into new, smaller energy conservative forms. Thus, Autobots and Decepticons became Maximals and Predacons, each ruled by a council, but with the Maximals firmly in control of the planet. Ravage put his espionage history to work serving under the Predacons' ruling triumvirate, the Tripredacus Council, as a covert agent—in his new bipedal Predacon body, his stealth abilities were enhanced from invisibility in darkness to true invisibility, imperceptible to both the naked eye and any scanning mechanisms (Although Silverbolt's enhanced senses did allow him to smell Ravage, he could only detect that there was somebody there that they couldn't see, rather than being able to pinpoint Ravage's exact location).
Despite his new body, his alternate mode was still a cassette tape (a nod to Ravage's original form, the CGI version matching his 1984 cell-animated illustration; his action figure, a retooling of Transmetal Cheetor transforms into a jaguar equipped with powerful rockets—the easier of the two classic forms to recreate). It is interesting to note that while Ravage had a new body in Beast Wars, when he transformed he still made the same classic transforming sound as the original series Autobots and Decepticons, unlike the Maximals and Predacons' quieter, more metallic sounds. He also spoke with a Russian accent.
With the Maximals' cooperation and the aid of Tarantulas, a Predacon secret police mole hidden in Megatron's forces, Ravage successfully arrested Megatron and put him in captivity. His craft was out of power, and while the Maximals sought energon to re-energize it, Megatron and Ravage were left together... long enough for Megatron to reveal that his plans to alter the timeline had been obtained from a message left by the original Megatron, Ravage's former commander. Discovering this, Ravage immediately switched sides along with Tarantulas (who was working towards his own agenda in any case), siding with Megatron in attacking the Maximal base. During the attack, Rattrap infiltrated Ravage's cruiser and planted a series of bombs on Tarantulas and quickly made his escape. Tarantulas exploded and the ship's interior was engulfed in flames. Ravage, piloting the ship saw the flames flying towards him and raised a fist of defeat, screaming out his last words:
Ravage was consumed by the explosion and the ship crashed, nearly taking out Rhinox and Rampage with it. A missile that Ravage had intended to destroy the Axalon with was left on the ship, ready for launch. When the ship crashed, Rampage was in front of the ship when it came to rest, defiantly laughing at cheating death as the ship halted mere inches from crushing him against a cliff surface. The ship's armed missile then launched and exploded in Rampage's face (who survived).
Ravage returned in command of the Predacons in the follow-up series The Ascending. Staging a huge diversionary attack, Ravage used his stealth features to sneak into the Maximal base, aiming to steal Razorbeast's chronal armband. With this he planned to free Megatron from his imprisonment in the Autobot Shuttle (as seen in "Nemesis pt 2"). Despite being defeated by Razorbeast and Snarl, Ravage was able to outwit them and gain the armband - but instead of changing the timestream got a disembodied Magmatron, who had been consigned to temporal limbo at the end of The Gathering, and now warned of the impending destruction of Cybertron at the hands of Unicron and Shokaract. Shaken by this knowledge, Ravage called a truce between his Predacons and the Maximals, but was too late to stop Razorbeast from being infected by Angolmois. Concluding a hasty alliance with Lio Convoy Ravage led his Predacons against Unicron's Herald, successfully downing him and extracting the Angolmois data they needed. Despite tensions rising over his dismissal of Razorbeast's sacrifice, Ravage accompanied the others back top Cybertron. In the subsequent battle he ambushed Unicron's Heralds, taking them out with an Angolmois grenade. He survived the battle, but his fate beyond this is unknown.
Throughout the late 20th Century, the government intelligence agency Triple I acquired a large number of Cybertronian artifacts from around the world, including a mysterious box that they dubbed "Schrödinger's Box". After the agency was disbanded, staff members continued to secretly store the items, until, in the early 21st Century, advances in technology resulting from human interaction with Transformers, they discovered the truth about the mystery box — it was the flight recorder from the buried remains of Ravage's Transwarp cruiser, left on Earth after the Beast Wars in prehistory. The flight recorder contained a duplicate of Ravage's personality labeled "File X-9," and their studies eventually allowed them to communicate with it. In exchange for sharing with them his knowledge of future events, Ravage desired that they create for him a new body. The Autobots on Earth had recently arranged for the construction of new bodies for themselves after infection by Cosmic Rust, and the Triple I staffers set up a fake project to arrange for the construction of one of these "Binaltech" bodies, in the form of a Chevrolet Corvette, for Ravage. Ravage's personality was transferred from the flight recorder into his new body, but to truly be brought to life, it required a spark. Coincidentally, the original, present-day incarnation of Ravage had recently been captured by the Earth Defense Command and stasis-locked into his cassette mode; purloined by the Triple I staffers, he was implanted into the cassette deck of the Binaltech body, providing it with a Spark, and uniting the past, present and future Ravage into one deadly whole. Easily overcoming the failsafes that the staffers had placed on his weapons systems, Ravage killed his benefactors, and, realizing that his involvement in the Beast Wars had failed to change history, set out to alter the timestream a different way.
Hijiacking a shuttle belonging to the Autobot Wheeljack, Ravage returned to Cybertron and set about locating the Kronosphere, a Decepticon time-machine developed by Shockwave. Locating and repairing the machine, Ravage made his play during the final, decisive battle between Megatron and Optimus Prime's forces in early 2005, turning the machine on Megatron's armada and transporting them into a rift in the space-time continuum. With this act, Ravage successfully altered the timeline — had this not occurred, Prime's forces would have been defeated and forced to withdraw to their bases on Cybertron's moons, setting up the events of The Transformers: The Movie, but with Ravage's success, they won the battle and retook Cybertron, thereby diverging the events of the Alternators timeline off from the animated series universe. Now, the Autobots would have to face the coming of Unicron alone, and when they were weakened in the wake of the battle, Ravage would bring Megatron back, and the Decepticons would finally crush their opponents.
Ravage subsequently installed Shockwave into a new Binaltech body to lead the remaining Decepticons in Megatron's absence. Unfortunately for Ravage, the Autobot known as Overdrive was aware of the space/time disturbances caused by his tinkering with future events, and teamed up with Wheeljack to capture Ravage and draw out his full plan. With a smirk of satisfaction, Ravage openly spilled the details of his plans, just as Unicron had been spotted on a collision course for Cybertron, revealing that his audacious plan may save some of those Autobots destined to meet their end during the events of the proper timeline (dubbed 'Prime Time' by Wheeljack, with Ravage's altered timeline noted as 'Ravage Time'), but that they were all expendable in his plans save Optimus, as he held the one thing that could defeat the Chaos Bringer. Realizing the complex dangers of Ravage's intentions, Optimus takes off with Ultra Magnus in a shuttle to intercept Unicron and use the Autobot Matrix of Leadership to destroy the planet-eater, while Autobot Skids is ordered to initiate "Operation: Distant Thunder", which would send the information gleaned from Ravage to their past selves at a point in history prior to the Decepticon cat's meddling, thus theoretically warning and preparing them for Ravage's assault on time and hopefully stopping him before he could do so, with the Binaltech project smoothing over most of any temporal hiccups afterwards. Just as Skids flips the final switch to send the data back in time, sensors pick up a huge Decepticon battalion bearing down on their location. Skids and his team manage to hold the battalion off long enough to send the datatracks and restore the proper timeline, but with the Binaltech timeline broken off by a mysterious Black Convoy from the future, Ravage still prevailed in some of his plans: Megatron and his group are still preserved and look to be reappearing soon, and Skids' failure to preserve their own timeline due to Black Convoy's meddling has left the Autobots somewhat unprepared for the oncoming storm. It's unknown what happened to Ravage after this.
Thus far, the only other "Ravage" character to appear in Transformers fiction, who is not the original Ravage, is the 2004 Transformers: Energon incarnation of the character, named Battle Ravage (Command Jaguar in Japan's Transformers: Superlink) for the same reason as the Alternator (which the Energon figure predated). Used as a series of grunt drones, Battle Ravage came in two forms, the later-appearing one called Command Ravage (or Command Jaguar, Desert type). Beyond his panther alternate mode, he bears no great similarity to the original Ravage. (Though his Energon weapons resemble the original Megatron's fusion cannon and gun mode.)
Approached by Scorponok to join his rebel squad, Battle Ravage accepted, and the group then found itself working under the direction of Alpha Quintesson, a go-between for the deactivated Unicron himself. Exposed to the reformatting powers of Unicron, the team were upgraded with new, more powerful Hyper Modes, and attacked the AlterEnergy facility in Australia on Earth - during which Battle Ravage pursued the human, Kicker — only to be stopped by the Autobots. Later, through Unicron's power, he and the other Terrorcons were multiplied into a vast army of cloned drones under the originals' command (much like the Vehicon Generals in Beast Machines). Battle Ravage's drones attacked Moscow until they were routed by an Autobot counter-attack and a vengeful Megatron.
The bankruptcy and subsequent closure of Dreamwave Productions left their story of Battle Ravage and the rest of the Transformers: Energon universe untold.
According to an online post by Roberto Orci Ravage was used in an early draft of the script where Scorponok was later used.
IGN: Where Soundwave goes, will Ravage follow? ORCI: Perhaps! You know, we had Ravage in an early draft of the first movie and Soundwave, and we couldn't do it right and I think this time hopefully we'll have the ability to do it. . Ravage now has since been confirmed for Transformers Revenge of the Fallen.
