Gonna go into Ein fanboy mode for a minute but if we were to get him as DLC I imagine we'd only get like 3-4 costumes so I think we should get these.
C1:
(DOA2 C1: Signature Ein and it was criminal to omit it in DOA4.)
C2:
(DOA2 C5: Standard Ein Karate Gi. DOA4 lacked the wrist wraps though, they make the outfit look much cooler.)
C3:
(DOA4 C2: The only good outfit he had in DOA4 but a pretty good look. You get the classic feel from the other outfits and the more modern DOA4 look from this, mandatory imo.)
C4:
(DOA2U C7: Super Ein!! Would be the most surprising choice but this just has to make a comeback. Even if I like Ein's DOA2U C6 and C2 more.)
His DOA2 C2 and C6 would also be awesome but we now how TN hates male characters so we'd be lucky to get these. Oh and that shirtless outfit with the chains and red pants can burn in a fire, and so can that horrible disco outfit. Seriously worst outfits ever and they both came back in DOA4.
