Zim

While most Irkens are expected to be ruthlessly loyal to the Empire, 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). When he is told by Tak in "Tak: The Hideous New Girl" that his "mission" was really an attempt to get rid of him, he simply rejects her statement as a lie. It is not entirely clear whether Zim is aware of his failings in the eyes of his leaders and is desperately trying to compensate for them, or whether he really is just completely oblivious to the opinions of others, as he had deluded himself into thinking he's "amazing" and can do no wrong. Despite this, Zim is innocently loyal and obedient to the Tallest, the Irken Empire, his planet and his people, and is willing to go to ridiculous lengths to please his leaders, to the point that he is zealously willing to endure pain or hardship in order to gain their respect. In the episode "Planet Jackers", Zim even undergoes a rather severe beating in the name of protecting his mission and Irken interests.
