Buzzstrike is a character from the animated series Transformers: Robots in Disguise, where he is identified as a unique Weaponizer Mini-Con. His history is marked by trauma, having been one of seven Mini-Cons kidnapped by Decepticons in his youth and taken to a location called Darkmount. There, he and the others were subjected to genetic modification, which granted them an unusual and powerful set of abilities.

This experimentation gave Buzzstrike the capacity to impart extra energy to full-sized Cybertronians, as well as to telepathically control the body of a host while in his weapon configuration. After Cybertron was restored, the Weaponizer Mini-Cons were kept in stasis. They were eventually freed by Starscream, who intended to use them for his own revenge, but the group escaped. Seeking safety, they hitched a ride to Earth with a ragtag Decepticon unit known as the Scavengers, led by Clawtrap.

Buzzstrike has a deeply conflicted personality. He rigidly adheres to traditional Autobot ideals of honor, justice, and fair play. However, the galaxy is a dangerous place, and for survival, he and his teammates have thrown their lot in with the Scavengers, a group that has little time for anything noble or idealistic. This contradiction defines his actions and motivations. He remains with the Scavengers not out of loyalty, but out of a grudging acceptance that without their protection, things would likely become much worse for him and his fellow Mini-Cons.

In terms of key relationships, Buzzstrike is specifically partnered with a Decepticon named Paralon. Their dynamic is purely transactional, as Paralon views Buzzstrike and his axe configuration as nothing more than a tool. Buzzstrike resents being treated this way but goes along with the arrangement, at least initially. This tense relationship is highlighted during a mission into the wreckage of Autobot Outpost Omega One. When Paralon decides to detonate a bomb that would kill incapacitated Autobots, Buzzstrike balks at the idea, revealing that despite his circumstances, he has no desire to take lives. In a later confrontation, after Paralon is knocked unconscious, Buzzstrike seizes the opportunity to take control of his partner's body. After defeating an Autobot, Buzzstrike chooses to flee and later lies to Paralon about what truly happened, showing a degree of self-preservation and manipulation born from his difficult situation.

Buzzstrike's role in the story evolves from being a reluctant member of a Decepticon scavenger team to a potential ally of the Autobots. Throughout the series, he and the other Weaponizers attempt to break free from the Scavengers, even stealing their ship at one point. During a confrontation with Bumblebee's team, the Weaponizers gain the upper hand using their body-stealing abilities. Their plans are complicated when they run out of fuel and encounter the Autobots again. After a temporary alliance, Buzzstrike and his companions are captured by Starscream, who merges with them to gain immense power. Following the Decepticon's defeat, Buzzstrike and the other Mini-Cons ultimately leave Earth on a spacecraft modified for space travel, seeking a new path forward.

Notable abilities of Buzzstrike include his nature as a Weaponizer, which allows him to transform into a battle axe. In this form, he can be wielded by larger robots or configured into chest armor. His most remarkable power is his ability to telepathically control a host body, as he demonstrates by taking command of Bumblebee. This power of body-stealing, combined with his energy-imparting capabilities, makes him a formidable asset. Over the course of his story arc, Buzzstrike shows a desire for a better situation, and it is suggested that he believes he would be better off pairing with the Autobot leader Bumblebee rather than remaining a tool for the Decepticons.
