In addition, Cady Heron also represents Brutus. Both Cady and Brutus are both sucked into a plan to destroy the Caesar figure (whether it is an actual murder or just social homicide). Janis Ian is the Cassius of Mean Girls. They both instigate the plot to destroy the Caesar figure and encourage their Brutus figure to act out their plan. Janis tells Cady that "there are two kinds of evil people. People who do evil stuff and people who see evil stuff being done and don't try to stop it." (III), which guilt trips Cady into helping Janis. Cassius similarly tells Brutus that "Men at some time are masters of their fates. .
The fault, dear Brutus, is not in our stars but in ourselves, that we are underlings" (IV), which gives Brutus the boost to help make him cave into becoming a conspirator. In The Tragedy of Julius Caesar and Mean Girls, the Caesar figure and the Brutus figure both fight for power during the story. In The Tragedy of Julius Caesar, Brutus fights for Caesar's power because he knows that Caesar will become a tyrant if he has it. Brutus feels he must end Caesar's life because "if it be aught toward the general good, Set honor in one eye and death i' th' other, And [he] will look on both indifferently, For let the gods so speed [him] as [he] love the name of honor more than [he fears] death" (V). In the second place, Mean Girl's Cady fights for Regina's power because Regina stole Cady's potential boyfriend, and she now agrees with Janis that Regina is ".a life ruiner. She ruins people's lives." (VI). Although Brutus and Cady have different motivation, they both still aim to take away the power Caesar and Regina have because they use it so negatively. .
Lastly, both The Tragedy of Julius Caesar and Mean Girls share a plot in which one main character intends to eradicate the evil dictator-like character.
