OVA
Description
Onslaught, who becomes the combined Decepticon warrior Bruticus, is a combiner leader who appears in the anime Transformers: Scramble City. Onslaught is the commander of the Combaticons, a five-member Decepticon military unit, and when the team merges he forms the torso and head of Bruticus, their towering gestalt form. The other Combaticons, Brawl, Swindle, Blast Off, and Vortex, form the limbs, and thanks to the Scramble Power system the limb positions can be swapped between the four smaller members.

In terms of background, Onslaught is the tactical brain of the group. He thinks of himself as a strategist who prefers to devise battle plans and let his soldiers carry them out rather than fight directly. When circumstances force him into combat, however, he becomes a relentless and furious fighter. He believes that the mind is the greatest weapon, and he is equipped with a powerful sonic stun gun and a missile cannon, while in his vehicle mode he can launch long-range photon missiles. As the core of the combined form, Onslaught is described as being considerably more intelligent than Bruticus, since the gestalt's mental capacity is far simpler than his own.

Bruticus himself is a very different presence from his component leader. As a combined warrior, he is extremely powerful but simple-minded, with small brain circuits that leave him with limited intelligence even compared with other combiners. He is cold-blooded in nature and takes pleasure in destroying Autobots, and once he begins to run wild he is almost impossible to stop. His abilities are primarily physical and destructive. He can smash metal bridges with a single chop of his hand, deliver punches powerful enough to pulverize heavy structures, lift enormous weights, and withstand most forms of artillery and radiation with his armored body. He also carries a sonic stun gun and a missile cannon and can attack his enemies with ultrasonic waves.

Within the story of the OVA, Bruticus serves as one of the Decepticons' heavy reinforcements. When Megatron launches an assault to prevent the completion of the Autobots' new transforming city, he deploys his combiner teams against the Autobot forces. The Combaticons arrive as Bruticus at a decisive moment and tip the battle in the Decepticons' favor. Working alongside the Stunticons' combined form Menasor, Bruticus helps to overwhelm the Aerialbots' combiner Superion, defeating him before the Autobots can turn the tide. Their victory is short-lived, because the Autobots' own giant city, Metroplex, arrives on the battlefield and defeats both Bruticus and Menasor with a single blast from its cannon, ending the Decepticon attack.

In terms of key relationships, Onslaught leads the Combaticons and is the direct link between the team's careful planning and Bruticus' raw force. Within the combined form, the individual personalities of the Combaticons are largely submerged, and Bruticus operates as a blunt instrument rather than a tactician. He also shares the battlefield with other Decepticon combiners, including Devastator and Menasor, as part of the coordinated Decepticon push against the Autobot project.

Bruticus has little personal development over the course of the OVA, since his role is that of a powerful enemy combatant rather than a character who undergoes change. His appearance mainly highlights the combiner mechanics of the Scramble Power system, in which the limbs of the combined robots can be exchanged and reconfigured during battle. His defeat at the hands of Metroplex underscores the immense scale and firepower of the Autobots' new weapon and brings the Decepticon offensive to a close. Overall, Onslaught and Bruticus together represent the contrast between strategic command and overwhelming brute strength, with Onslaught supplying the cunning leadership of the Combaticons and Bruticus supplying the devastating power that the team unleashes once combined.
