Three Heroes? Okay let's check both fighter passes and see who is a Hero or Villain.
= Hero (Saves the world from a god and changes the hearts of corrupt megalomaniacs)
= Not sure about him though his name probably does give some kind of hint.
= Heroes (Saves his sister from a Witch and stops the same witch from stealing everyone's life energy)
= Hero (Beats up bad guys like Geese Howard and has no patience for people who are cruel to others)
= Hero (Does the same thing as any other Fire Emblem protagonist)
= Kind of? (She can beat up bad guys but not for justice but because they're in the way of getting the championship belt)
= Villain (Killing the Ender Dragon is the only true objective in Minecraft but because it has no motive to destroy the world and minds it's own business, Killing it is a random act of violence. Sure you can save villagers but that's not required to beat the game.)
= Villain (Same as Steve)
= Villain (Wants to kill innocent villagers)
= Passive (Only bothers people who aggravate it)
= Villain (Killed innocent people with the Nilbelm Incident and has Supernova which is shown to destroy the world)
= Hero (Goes on a journey with Rex to save the world)
= Hero (Same as Pyra)
= Villain (Since Tekken 2, He made the Mishima Zaibatsu into a more ruthless criminal organisation with crimes including kidnapping, extorting money from other companies, smuggling exotic animals, etc.)
