Who is the best character in the MCU?

The anti-heroes/geniuses: Yondu, although I do miss him a bit. Same goes for Tullk. Executioner, although he could have been done WAY better. Dr Erskine and Yinsen. Hulk (I don't care if some shitty titty director(s) messed up my favorite character(s) I won't give up on them, not just yet). And last but not least, the one and only Watcher Informant, aka Stan Lee.

Iron Man
