Franklin Richards is a fictional character that appears in the Marvel Universe.
Franklin is an Omega-Level mutant with vast reality-manipulating powers. He is the young son of Mister Fantastic and the Invisible Woman of the Fantastic Four and the older brother of Valeria Richards. His parents named him Franklin Benjamin Richards; his middle name is taken from his Godfather Benjamin Jacob Grimm, the Thing. Franklin also shares the same middle name as Peter Benjamin Parker, Spider-Man, who once told Franklin "Uncle Bens are always right". Franklin's first name comes from Franklin Storm, his maternal grandfather.
During a battle between Ultron-7 and the Fantastic Four, the energy leaking from Ultron awoke Franklin and his powers. The energy release from Franklin was enough to defeat Ultron. Free of the excess energy, Franklin was returned to his normal power level.
While still little, Franklin was looked after by an elderly woman called Agatha Harkness who turned out to be a benevolent witch. She and Franklin became very attached to one another — the latter calling her "Aunt Agatha" — and lived together at her old residence of Whisper Hill (which was regularly destroyed and rebuilt). Eventually Agatha returned to live in the secret witch community of New Salem, Colorado, and Franklin moved in permanently with the FF. His powers were manifesting themselves, however, and he even gained the ability to destroy things from a distance.
Franklin later even aged himself into an adult, becoming known as the Avatar. In this form, Franklin had vast amounts of power to manipulate energy, but he quickly restored himself to childhood.
Franklin's adventures with Power Pack gained him an enemy in the alien Zn'rx, and allies and friends in the Kymellian Whitemanes. Franklin was particularly close to the young Kofi Whitemane, who declared Franklin an honorary cousin in much the same way as the children of Power Pack had been adopted as honorary Whitemanes. Franklin also regarded the Power children and their parents as a sort of surrogate family — his association with them beginning at a time when he was feeling particularly distant from his parents at a time when they were living at Avengers Mansion. At this period Franklin also bonded emotionally with Avengers associate and manservant Edwin Jarvis, as Jarvis was his primary caretaker while Franklin stayed at the mansion. His friendship with the Power children also gave Franklin a taste of life among siblings, which the lonely Franklin would not experience until much later when his sister Valeria was born.
The Richards and Power families became fast friends, though neither family's parents realized that any of the children other than Franklin were super-powered (though Susan and Reed discovered this later). Franklin even kept his membership of Power Pack a secret from his own parents: when he appeared before them in image form (see above) he would stick to ordinary clothes, only appearing in his Power Pack outfit before other heroes such as Kitty Pryde.
Franklin even lived with the Power family for a time, when his parents decided that a super-hero headquarters was a dangerous place for a child to live, and wanted Franklin to spend time in a "normal" family environment. He returned to his family when Power Pack temporarily left Earth for the Kymellian homeworld.
It was then revealed that in another possible future timeline, Franklin Richards would, with Rachel Summers, father a terrible time- and dimension-traveling supervillain named Hyperstorm. Hyperstorm kidnapped Psi-Lord and replaced him with his child self.
Franklin travels with several X-Men to the farm owned by Hank McCoy's parents. He plays with Artie Maddicks and Leech, both mutant children. During his stay with Generation X, Franklin, Artie and Leech meet with Howard the Duck and a Rigellian ally of Thor named Tana Nile. The plant-controlling villain Black Tom Cassidy attacks at the Danger Grotto tree house they enjoy staying in. Howard saves them all, seemingly destroying Black Tom. Later, Franklin and Alicia attend an unveiling of a statue commemorating the sacrifices made by the heroes. It focuses on Thor's hammer, Captain America's shield and his father's stretching arm. The Mad Thinker, who dislikes the statue, attacks the gathering with an array of shape-changing robots. The Thunderbolts, a group of villains pretending to be heroes, defeat the robots and safely rescue Franklin. The Celestials recognized that Franklin represented the culmination of their genetic experiments, that he had power to rival even theirs. Ashema, one of the Celestials, representing herself as a human, visits Franklin. Ultimately, Franklin, Ashema and other forces allowed the rightful heroes to return and both universes to remain functioning.
Later, Onslaught is reformed with the mutant energy released from Decimation, tries to get its revenge on Franklin.
Shortly afterwards, Doctor Doom made a pact with the Haazareth, to gain vast magical power. During Doom's attacks upon the Fantastic Four, Franklin was sucked into Hell, by the Haazareth. After the defeat of Doom, his parents rescued him. Franklin had a hard time coping with the traumatic experience of being tormented in Hell. With help from the Thing and Franklin's mother, he made a complete mental recovery.
Because of the danger of their adventures, Child Welfare questioned the safety of the Baxter Building, due to the numerous super villain attacks on it. After much reluctance, Reed and Sue agreed that if necessary, their children could be taken away. However, an initial condition was that a "dummy" safe-house was to be set up, and a press release to be announced that the children had already been moved. It is uncertain exactly which of the FF's enemies carried out the attack, or why (there is speculation that Reed carried out the attack himself to allow him and Sue to keep the kids), but it was enough to convince Child Welfare.
When Franklin flees to Counter-Earth, Onslaught follows him. While the Avengers assess their new threat which did not exist until Franklin appeared, they take into account what the boy says about Onslaught. However, they are in disbelief that he is the son of Susan Storm and Reed Richards of the Fantastic Four as they are not married in their reality.
After a brief skirmish, the heroes and villains decide to work together to defeat Onslaught, but it is Rikki "Bucky" Barnes who defeats him, using a Fantasti-Car to send them both through the Negative Zone barrier in the Fantastic Four's lab, trapping them. Franklin returns home, Bucky finds herself on Earth 616, and Onslaught is last seen floating outside the Area 42 Prison in the Negative Zone.
It must be noted that the adult Franklin Richards seen in the present of Earth-616 during the Days of Future Past crossover tapped into the powers of Rachel Summers, augmenting his own abilities with the near-infinite energy of the Phoenix Force.
The Exiles, a group of superheroes taken from several different realities, traveled to a future Earth where their mission was to stop Franklin Richards' son from conquering that world. Franklin himself is not shown in this storyline.
In the out-of-continuity humor series Franklin Richards: Son of a Genius, Franklin is portrayed as a Calvin-esque troublemaker who can't resist "playing" with his father's inventions, with disastrous results. Franklin must then scramble to reverse the effects/clean up after the results of his "play", with the help of his long-suffering robot nanny H.E.R.B.I.E. (who essentially plays a Hobbes-esque role), or face punishment from his parents. In the Son of a Genius one-shot Everybody Loves Franklin, Franklin encountered a non-superpowered version of Katie Power (the "real" Franklin's former Power Pack teammate); while Franklin at first disliked Katie in stereotypical young boy fashion, he seemed to develop a crush on her (reciprocated by Katie) when he discovered that she had a talent for mayhem similar to his own.
Franklin Richards: Son of a Genius began as a series of back-up strips, each one appearing in all Marvel books released in a certain publishing week. The strips were well-received by Marvel readership and the concept was granted a self-titled one-shot, which primarily reprinted the published strips to date. A second one-shot followed, subtitled Everybody Loves Franklin, with new material. A third one-shot, a Summer Special of new stories, and a fourth, subtitled Happy Franksgiving; in which includes a unique mini-tale involving Thanksgiving Day, have already been released. And a fifth one-shot titled, World Be Warned, It's Franklin Richards, Son of a Genius was followed by Fantastic Four Presents Franklin Richards, Son of a Genius: Monster Mash. All of the Son of a Genius stories to date have been drawn by Chris Eliopoulos and co-written by Eliopoulos and Marc Sumerak.
A Franklin Richards: Son of a Genius one-shot entitled Franklin Richards: Not-So-Secret Invasion sees Franklin and H.E.R.B.I.E. face Skrull invaders in the title story, which parodies Marvel's 2008 crossover event Secret Invasion. Franklin easily outsmarts and overpowers the hapless Skrull spy who tries to replace him.
After this adventure, Julie Power creates a costume for Franklin, dubbing him the "honorary fifth member". The costume looks like a standard Power Pack costume, done in orange and having the all-seeing eye icon of his "tattletale" costume from the original series. Although the costume was made of regular materials instead of using the alien materials that accounts for the special abilities of the other Power Pack costumes; Franklin's father has modified the "Tattletale" costume using unstable molecules.
In the Power Pack: Day One miniseries; Franklin is staying with the Power family, due to the Fantastic Four going on a space mission. During his stay, Franklin is learning from the Power siblings the origin of how they became Power Pack.
In the first issue of the Skrulls vs. Power Pack miniseries; Franklin and the Power siblings were at a bowling alley, when they were attacked by bounty hunters. While the hunters captured and delivered the Pack to Patchworld; Franklin managed to return to the Baxter Building to ask his parents to help rescue them, but instead depended upon the aid from both the Smartship Friday and his robot nanny H.E.R.B.I.E.
This version of Franklin to this date hasn't displayed any powers; however, he does have great courage and intelligence. He also has some impressive high-tech gadgets that Reed and Franklin built together. These save his life during the Galactic bounty-hunter attack.
With the main continuity, the "Son of a Genius" series, and the all ages version of Power Pack; there are now three different versions {within the different continuities} of Franklin Richards fighting the Skrull Invasion.
In the game Marvel: Ultimate Alliance, when speaking to the Invisible Woman, Franklin was briefly mentioned.
