Definitely Karnak for me. I don't know how others feel about his current run but I love the sadistic, slightly arrogant, and sarcastic, savage brawler Ellis turned him into. I thought he was lame from the first time I saw him in Hudlin's black panther and wasn't a fan of his look (though I've warmed up to it and would like to see a mix between it and his current look, which I also love). Ellis' Karnak is seriously stacking feats on top of feats, from bullet timing, casually rupturing organs and breaking bones with a slight touch and using his own voice to make scores of heads explode. One of my favourite Marvel characters, even though I don't have many as a new comic book reader.

Close second would be the Vision, thanks to Tom King's fantastic run, and Thor Odinson after reading the God Butcher storyline.
