You mentioned new party members, I think, in one of the other threads (yes, there's only 3, I'm lazy). I'm gonna take a guess and say Red might be one of them.
1. Same sprites as Kuros, so it would be easy to manipulate his design and emotes.
2. And most notably, 'If you can't beat 'em, join 'em.'
Seems at this time, Red Knight has nothing to fear from his wizardly master Malkil, being immune to magic (I assume he just gets better when turned into a slime), but for wealth and action, he would go with the trio, especially considering he's been schooled so many times by them.
Of course, in that case, Malkil would probably render him less than invulnerable as punishment, and to keep things in line.

Kuros: Why bother fighting anything? Mr Invincible can take care of it.
CG: The hell he can, I wanna fight already! I trashed a whole techno empire, and now I'm booting bats and snakes.
Link: Kuros, you're kidding me? I've mopped the floor with him left and right. He couldnt destroy a damp paper bag.
Red Knight: ...why do you say things that you know will hurt me?
CG: I guess Link found another weakness in that armor. Wuss!
