Henry - Kingdom Come: Deliverance (can be played morally grey, but mostly defaults to goodly choices)
Ratchet - Ratchet and Clank series (I haven't played the last ~3 games, so this may have changed)
Spider-Man - uh, the Spiderman games (feels wrong to say he's from a game, which probably means I'm stretching).
Really interesting thought exercise, surprisingly difficult.
