This list is not to be confused with a list of top ten villains. The characters listed below are strictly the jerks. Note that the jerks in comics can be heroes or villains. Most of the characters who are criminally insane do not qualify as jerks, as most of them are slaves to their mental diseases. These people below are complete jerks because they want to be.
Oswald Cobblepot, ("The Penguin") is the personification of the abuse of power. He is a constant reminder to Bruce Wayne of what could happen if he were to be unethical with his own fortune. Cobblepot is a mover and shaker in Gotham City, being a descendant of one of the Gotham's most prestigious founding families. However, instead of using his inherited fortune for philanthropy, Cobblepot would rather swindle people out of their own finances and livelihood, whether it be through his notorious Iceberg Casino, gang warfare or even through local politics! No matter what plan Cobblepot has cooking for Gotham, you can be sure he will try to keep his own hands clean.
Mr. Sinister just cannot get enough of himself. As a scientific genius in the fields of biology, genetics, physics and engineering, he has mastered the science of cloning. When he is not trying to manipulate his enemies into slavery through telekinesis, he is making tons of copies of himself in fear of losing his immortality. He was even able to turn the whole city of San Francisco into his own personal city which he called, "Sinister, London." Modeled after Victorian-era architecture and style, the only inhabitants of Sinister, London were clones of Mr. Sinister, go figure!
M.O.D.O.K., or (Mental Organism Designed Only for Killing), is an ungrateful, malicious jerk. He had the audacity to turn on the scientists that created him, taking control of AIM, (Advanced Idea Mechanics). Since that point, he has been a constant fly in the ointment to the likes of Ms. Marvel, Captain America and the Avengers. Although usually thwarted with ease by the world's mightiest heroes, MODOK has been a constant annoyance over the years. He is most noted for weaponizing biological agents to terrorize millions, striking deals with other evil-doers and kidnapping the girlfriends of superheroes.
Thaal Sinestro is an embodiment of arrogance to say the least. Once a mentor to Hal Jordan during his "rookie season" with the Green Lantern Corps, Sinestro has become the leader of the Yellow Lanterns, (Sinestro Corps), and arch nemesis of the Green Lanterns. This turncoat harnessed the power of fear, which negates the will power utilized by the Green Lanterns to a certain extent. (Although Sinestro finds out later that yellow light is not an even match for green.) He has been responsible for the repression of his own people, conquering and ruling his home planet of Korugar that he was once chosen to protect. He is also the murderer of the guardians of the universe. I suppose that no matter how many times Hal Jordan tries to befriend him and inspire him to do good, you just can't teach an old dog new tricks.
Loki, brother of Thor, "God of Lies and Mischief," is the classic trickster-jerk. Within his bag of tricks are telepathy, flight, shape-shifting, inter-dimensional teleportation, psionic abilities, astral projection, molecular rearrangement, energy blasts, illusion casting and hypnosis. With this large array of super powers, Loki has tried all kinds of evil schemes in a quest for power, including the overtaking of both Asgard and Earth. He always makes deals with the scum of the Marvel Universe in order to get what he wants. Whether he is trying to kill his stepbrother, "The God of Thunder," kidnap Jane Foster or use his amazing powers of deception to endanger all of Asgard, if Loki is present, call the Avengers!
