Mixmaster

Mixmaster is a Constructicon from Transformers Animated. His weapon is his arm-mounted cement mixers. He transforms into a cement truck.

=== Animated Cartoon===

He makes his first appearance in "Rise of the Constructicons" alongside Scrapper. After the pair are brought to life by a fragment of the Allspark, Scrapper points out that his name must be "Mixmaster", after reading his truck mode's brand name. Initially the two befriend Bulkhead, but are hired by Megatron after his Decepticons tricked the two into helping them steal supplies to construct a Space Bridge by offering the Constructicons oil as payment for their service. After drinking contaminated oil provided by Bulkhead, the two exploded and lost their memories of any of the preceding events. They later return in "Sari, No One's Home", going on an oil stealing frenzy before following a trail of oil spilled by Bumblebee to the Autobot's base. In spite of Sari defending the base on the assumption that they're working for the Decepticons again, Mixmaster ignored Scrapper's pleas to leave as he vaguely remembered the place held the best tasting oil they ever had. Once they finally forced out, the two run into Blitzwing, who offers them Decepticon oil which Mixmaster recognizes as he takes them to finish the Space Bridge.

Scrapper and Mixmaster are formally inducted into the Decepticon forces in the "A Bridge Too Close" two-parter. They are branded with the Decepticon symbols, and their color schemes are changed to match those of their G1 selves. When the Decepticon base starts to cave in, Scrapper and Mix stay behind, in an attempt to save their oil supply, and end up buried under tons of rock. But the two survived and went into hiding at a auto factory, watching the red cars getting built, before they are found by Bulkhead in the season 3 episode "Three's a Crowd". Though relucant to help him at first, the two decide to moonlight to help rebuild the space bridge in Sumdac tower. However, the newly online Dirt Boss quickly established himself as their foreman. Mixmaster then paricipated in Dirt Boss's plan to control Detroit's oil, resulting him getting Scrapper's fist lodged in his chestplate before the three Constructicons ended up tranwarped in the lake near Dinobot Island on an oil tanker before it explodes.
