Comic book characters you started to dislike overtime?

What are some characters that you use to absolutely liked or enjoy reading about that overtime you started to not find them as interesting or hate?

Mines have to be Venom and Flash.

@randybutternubs: Based in continuity or just reading more stories?

Abomination & Thor.

Probably Doomsday, because a creature that can adapt to what killed it prior makes it hard to use efficiently since I don't think it can be nerfed. I like the concept of an seemingly unstoppable monster that adapts and changes in unexpected ways, though.

Hal Jordan I guess.

I guess maybe Tim Drake or Jean Grey. However, I've never liked Jean Grey anyway.
