Impulsive, self-centered, vain, insecure, and unstable, Master Shake is both the self-proclaimed leader of the Aqua Teen Hunger Force and arguably its weakest link in terms of cohesion. Best described as a free spirit at the best of times and an active detriment at the worst, the sentient milkshake repeatedly proves himself to be foolish and one part of the duo of dorks that play off the straight man of their team, Frylock. While not always the case, Master Shake is often the cause of many of the Aqua Teens’ hijinks, exacerbated by his utter lack of self-awareness on top of his greed, misplaced trust, impulses, secondary emotions, and insecurities.

Predictably unpredictable, Master Shake struggles to regulate his emotion. His moods changing from more or less passive to massively exhilarated, hopeless, viciously angry, then back to calm at a moments notice. This trend of instability also transfers into his relationships, namely with his two brothers and neighbor, Frylock, Meatwad, and Carl respectively. Carrying an easily bruised ego and an alarmingly short fuse, Master Shake is effortless to set off. His wrath wildly out of proportion to the situation at hand, he makes his fury known through verbal and physical abuse as well as a ruinous amount of property destruction. More concerned about money, fame, and his fallacious depiction of what he believes love is than the well-being and safety of others and himself, Shake shows a constant childish egocentrism that harms everyone involved.

Desperate for any shred of attention, be it positive or negative, Shake lives to be an embodiment of spectacle. There is no length he won't go to, nor end he won't justify to cultivate some form of attention or acknowledgment. He feels entitled to their attention and feels that they should love and accept him for who he thinks he is – rather than his true self that he is oblivious to. Master Shake carries with him some traits associated with worst types of actors, politicians, and people, all for that sole purpose of attention.

In this series, Master Shake is the news anchor for the city of Fort Inkei.
