There's a touch of the medieval alchemist about Mixmaster. There's almost nothing, inert or otherwise (including living metal), he won't reduce down to a stew of ores and chemicals in his seething rotating acid cauldron and then output as a new raw material.
The others think he's got a few loose microchips, the way he cackles as he goes about his work, but it's hard to argue with the results.
Mixmaster was introduced to the game at the same time as Jazz.
It is not uncommon to find Mixmaster donning a different color scheme when looking at him during a scouting mission. This is believed to be a glitch encountered when an Autobot player looks at another Autobot base as an adversary and Space Ape has transformed the Autobots and their base into Decepticon versions for the purpose of the war.
