Pit is a major character in both Robin & Shulk and Luigi's New Mansion at the same time. And while they aren't the exact same character, they both act identically so you shouldn't have to do different voices for each.

As for what he's like, Pit is a rash decision maker and often gets into fights because he refuses to listen. He's also very kind to his friends, even his sidekick; Dark Pit, who he's always getting angry at. Speaking of Dark Pit, him and Pit have a sort of brother like relationship where Dark Pit follows him around all the time and Pit gets mad at him and tells him to die.

For his voice, try to mimic how he sounds in Uprising. He's also very passionate so try and emphasise alot of his words.

The lines I picked for the audition are pretty aggressive so don't hold back! (the louder the better ;])
