Hades is excusable because he's naturally evil, and he's great at being a dark humor character/comic relief. Dyntos... He's just awesome man. He doesn't make fun of Pit at all compared to Palutena, has the power to take over the world, but he's, and I quote, "Not interested.", stays neutral. and rewards Pit if he proves his strength, which gives you a good sense of accomplishment when you do.
