Wesley Crusher

Ensign Wesley Crusher is a recurring character in Star Trek franchise: Star Trek: The Next Generation and Star Trek: Nemesis

Why He Sucks

 * 1) He's a complete Creator's Pet character who aware of how hated he is, but stays on the show anyway, to the point where he's one of the most well-known examples and the former trope namer. Then there's the 1987 Writer's Strike.
 * 2) He loves to meddle in just anything the characters are doing.
 * 3) He can be considered a Gary Stu of some kind since he solves virtually every major problem or crisis there is, and is praised by everybody for what he does even when he doesn't deserve to be praised.
 * 4) Speaking of which, some of the crises happened because of him, and he still get praised for it!
 * 5) Anytime he does something wrong for the characters, he doesn't get punished for it.
