Lawful Douchebag.
Maybe she could just kill maxi and help move the plot forward.
But Maxi can't die. He's probably been brought back to life more times than Zas has. But I'd rather see Ashlotte replacing Astaroth, I think that's what happened in her story in 4.
As far as evil characters, there's room for interpretation.
Nightmare is Soul Edge, so he's pretty much the most obvious "evil" character.
Tira is nucking futs and in love with Soul Edge and serves it obsessively. She is also the one responsible for moving the corruption of Pyrrha along into the next Nightmare so she's evil.
Oprah is evil by association with Tira and Soul Edge.
Dampierre could be considered evil, but more of a petty, selfish kind than NM and the like.
Astaroth uhhh.... I don't know anything about him.
Aeon was victim to a curse I believe, I'd see him as more neutral.
Elysium can be considered evil in the same way Izanami from P4 can, which is pretty much Lawful Neutral exaggerated.
Algol... He seems to be Chaotic Neutral at best, but he could be groomed into another, bigger antagonist in the future.
