As much as Mixmaster enjoys being a chemist, his real love is music. He constantly hums himself as he works, and any chance he gets he breaks loose and lays down some sweet tracks for the other Constructicons. He sees himself as the morale officer of the group, and tries to keep Hook’s spirits up when the surgeon gets down on himself for not being able to do enough to save everyone. Mixmaster gets along well with Soundwave, and longs for a time when he can spend less time building war fortifications and more time jamming with his friends.
