Mixmaster

Mixmaster was a Decepticon and secondary character in the scrumblebee comic. He was a chemist, always creating new acid compounds to use against the Autobots. He also used his cement mixer alt mode to help with construction projects.

 Shockwave's Revenge Arc 

Mixmaster was stationed at Shockwave's outpost, but didn't appear until later. After they joined forces with Sixshot, Liokaiser, and Triggerhappy, he helped construct a ship to leave the Beast Planet. He was present during Shockwave's mutiny. He later led the second wave of troops in the battle. He fought Hexatron, and later woke up the injured Darkwind. He retreated from the battle along with Darkwind, Triggerhappy, Quake, and Astrotrain.

 The Galvatron Crisis Arc 

At some point between the Shockwave's Revenge and Galvatron Crisis Arcs, Mixmaster and the others met up with Sixshot, the Combaticons, and the Destrons on Planet X. He, along with everyone else, joined Galvatron. He later led a raid on Optimus Prime's camp with Triggerhappy and Quake. He used a newly developed acid compound on the injured Hot Shot, which led to his eventual death. This enraged Grimlock, who attacked him in his dinosaur mode. He later helped construct the Nemesis, and presented it to Galvatron. He later participated in the Final Battle. He had a rematch against Grimlock. He fired acid at Grimlock, but Slug took it instead. Grimlock then equipped his energy blade, and sliced his shoulder, and he fell to the ground. Grimlock then stabbed Mixmaster in the chest, killing him.
