Who's your favorite MCU superhero?

I don't think we've ever done this poll before so here we go. Who's your favorite MCU superhero? I'm limiting the poll to only the main superheroes (Cap, IM, Thor, etc.) and recurring sidekicks (Falcon, Warmachine, etc.). One off side characters like Valkyrie are not included in the poll but you can certainly post about them. No villains, I can make a separate thread for that, but I will make a consideration for Loki and Bucky as they did convert to heroes later on. Also just limiting to movie characters. 

Now choose!
