1. Thanos (Avengers: Infinity War, Avengers: Endgame)

Ant-Man is canonically the friendliest Marvel hero, as in he's the only one who actually has friends outside of his heroic life. Even when he was in prison, he had buddies who were proud to see him off on his release day (shout out to Peachy, who made sure Scott got a hug after his goodbye punch).
1 Spider-Man Is The Original Hard Luck Hero
