The character is partnered with the character Monzo, who in the U.S. continuity was an ex-hyperwrestler turned night club owner by trade. Weirdwolf converts from robot to wolf and back, while Monzo converts from human-like figure into the robot's head (hence the term Headmaster). The toy was released in 1987.
According to Weirdwolf's Tech spec, he is a Tracker and has a few screws loose in his head. He speaks to himself in a "singsong backward way" and can leap .8 miles. Weirdwolf is armed with a photon pistol and thermal sword.
One of his most prominent actions during this period was to act as bait for a trap alongside the other Decepticon Headmasters. The plan worked, luring the Autobot Headmasters to the Fortress of Despair, where the Decepticons captured Highbrow, planning to use him to perfect their own Headmaster process. The plan failed when Highbrow forced Scorponok to flee. (Transformers U.K. 130-131)
Weirdwolf participated in many battles against the Autobots before coming to Earth as part of Scorponok's group.
Weirdwolf would appear again in issue #49, "The Underbase Saga Part 3, Cold War!" In this story he was a member of the Decepticon forces under Scorponok's command. They were tricked into fighting the Decepticon forces under Ratbat's command by Starscream, who used the battle to steal Scorponok's ship and get to the Underbase.
Issue #248 of the Marvel U.K. Transformers comic featured a story called "Fallen Star", where Starscream began to doubt himself, despite being of the most powerful Transformers. Soundwave, Mindwipe and Weirdwolf feared Starscream would attack, but Starscream thought they were laughing at him behind his back. Leaving Starscream came across the Autobots Chainclaw, Cloudburst and Getaway, who were assigned by Optimus Prime to spy on him. Starscream soundly defeated all three Autobots and regained his self confidence.
He appeared later in the Transformers: Generation 2 comic during the attack on Earth, noting it was "feeding time" as he transformed to wolf mode. It is unclear whether he survived the subsequent battles against Jhiaxus' forces and the Swarm.
