I expect a few questions, so here are a few answers:
Q: What's with all the scars and bandages?
A: In this universe, I betrayed Hades, going to overthrow him(somehow) and become the new ruler of the Underworld. However it didn't work as I was left with several scars and a damaged eye. I'm not blind in it, but vision is blurred.
Q: What's with the wings?
A: After Pit's first encounter with Dusk(another name I go by), while they did fight, he learns that Dusk betrayed Hades, but doesn't exactly trust him, since Dusk is a demon. Not that Dusk cares, since he doesn't trust him yet either. They re-unite in a later battle, during it, Pit's wings begin to burn(from using Power of Flight for too long), and out of an instinct of sort, Dusk leaped and grabbed him before too much pain was caused on the angel. Later, the 2 became allies and Palu blessed the Demon by giving them the wings they had when they were once an Angel, beautiful wings that resemble the sunset, which is why they got their name. Dusk.
Q: How do they interact with Pit or Pittoo?
A: Dusk calls Pit "Angel Boy" or "Kid", and Dark Pit "Kiddo" or "Fallen Boy". They both hate the nicknames, but grow to get used to it. most of the time it's Pit asking Dusk a LOAD of questions to learn more about them and the Underworld.
