Zim

Zim is considered overzealous even by their standards: Brash, arrogant, and overconfident, Zim's tendency to cause wanton destruction makes him a danger to himself and his own people, yet he still considers himself a mighty Irken warrior. In addition, he is acutely narcissistic and megalomaniacal, congratulating himself on even the smallest of successes; these, however, are few and far between. Despite his self-proclaimed greatness, Zim rarely succeeds in his attempts and is held up as a complete laughingstock, a scapegoat, or a figure of contempt by his own species, a fact that he is either oblivious to or simply chooses not to notice; this is hinted at by the fact that due to his self-absorbed nature, it prevents Zim from seeing his failures, past and present. He claims to be proud of all the past disasters he has caused, and rarely acknowledges his defeats in his present mission on Earth (often blaming them on other characters, or other factors, or completely changing the subject).
