All Might is a very bubbly and happy person, he’s a great hero and always makes sure to keep everyone happy and safe. He’s a very sweet and gentle guy, but harsh and rough when it comes to fighting off villains. Endeavor hates All Might and always tries to take his place at the Number 1 hero, wanting to be the best. He’s a very stern and angry man and very, very rarely smiles. If you see him smile, keep that in your mind, it may be the last time you see it.
