Thunder Mayhem
- Thunder Mayhem is a Decepticon combiner from the Generation 1 continuity family.

Thunder Mayhem is a monster, a blot upon the universe. Born of the mad science of Shockwave and Thunderwing, the combined form of the Mayhem Attack Squad is unique. And not just because it consists of six sparks in a body made from five, or because that sixth which gives this entity its life glows an unnatural green. No other combiner in existence is as strong, or durable, or dangerous. Entire armies have fought it, and entire armies have fallen, either to its indomitable strength, its mighty array of weapons, or its ruthless intellect.
However, while to the Decepticons this unstoppable juggernaut might be an unqualified success, this relentless beast has no love for its kin, and will destroy any who stand against it without the slightest hesitation. What will happen when its' rampage across Cybertron is finished is unknown, but it likely will not simply sit and enjoy itself in the ruins of one world. Perhaps the only thing capable of putting an end to this creature is another, equally horrific monster...
Those who form this dread behemoth include:
- Bludgeon (leader)
- Needlenose
- Grabuge
- Spinister
- Windsweeper
Fiction
Of Masters and Mayhem
Thunder Mayhem's origins trace back to two different mad experiments. The first involved the living weapon Toxitron, who'd been made in the image of Optimus Prime himself. At some point, a scientist (either Shockwave or someone working under him) attempted to recreate the Creation Matrix inside the creature. The result was not entirely successful, but did give the Decepticons a shell.
The second came from the ambitious but very insane Thunderwing, who experimented on himself in the hopes of unlocking arcane power. What he managed was to turn his spark green. Learning of this, Shockwave had Thunderwing imprisoned and removed his spark, before placing it in the shell. Eventually the spark-infused shell was made a part of the combined form of the Mayhem Attack Squad, granting it life. Deadly Aim
Thunder Mayhem ravaged Cybertron, devastating Autobot and Decepticon alike, including the legendary Autobot commando unit the Wreckers. In the course of this one-sided war, it destroyed fellow combiners Bruticus and Defensor. At one of the last skirmishes, at Kaon, it faced Superion and Menasor, whom it also destroyed - Superior by slicing his components into pieces, and Menasor by shooting him with a weapon so powerful the combiner was torn to shreds. Deadly Aim
Eventually, Thunder Mayhem's rampage had cost so many that barely any from either side survived. Some even believed it had destroyed Cybertron itself Life Finds a Way But it hadn't. Deadly Aim
In the desperate times that followed, surviving Wrecker leader Impactor swore vengeance, Of Masters and Mayhem Impactor profile deciding to avoid executing Decepticon infiltrator Counterpunch in favor of enlisting his help against Thunder Mayhem. The Truth We Make They began searching for any survivors who could help get revenge Life Finds a Way even if they were, in Toxitron's case, just as monstrous. The Toxic Transformer
