Characters who deserve more respect
What characters in your opinion generally get written below their full potential?
Please don't name characters who have some low-showings but otherwise get plenty of good showings and respect from writers (IE: Thor, Superman, Hulk, etc).
It doesn't even have to necessarily be about power/combat showings.
For instance one of my choices is R'as Al Ghul. The guy is billed as Batman's most dangerous foe and has been plotting and scheming for centuries and yet aside from a few instances like Tower of Babel he's never really shown being the global threat that he should be.
For the same reasons I'd also name Apocalypse. I'm not close to a fan of the guy, I hate his design and his personality is irksome, but I recognize that the guy isn't generally given the respect by his writers that he should given his billing as R'as Al Ghul on steroids with Celestial technology.
Marvel Ares is another. I hate that they make the God of War a Meta.
Sodam Yat. Nuff said.
