User blog comment:Jkphantom9/So, about Sun's Team.../@comment-10380701-20140524090806

I'm betting a lot of lien in that the redhead is the Pig, since he appears to be the relaxed and rebellious type. I dunno about his appetite though. Trenchcoat may be the River Demon, given his stoic looks in the opening.

It's the bluehead that I'm having some thoughts about. There's a chance he's the Dragon Horse (referred to as Yulong on an earlier comment) or that he's the monk. But he seems to heavily tilt into the Dragon Horse, based on the fact that one of the TV series of Journey to the West had the Dragon Horse with spiky hair.

I... really can't make a valid speculation as we've only seen their appearance.

For all we know, Sun's team is actually composed of Chinese mythological characters. There's a chance that Trenchcoat is Guan Yu, for example.
