Deimos as an extra character (God of War)
Kratos' pre-order costume is Deimos, actually.
I was thinking they could save secondary characters for DLC. I'd pay 3 bucks to play as Dr. Nefarious.
With the same exact move-set as Kratos.
It's like in Brawl where Princess Peach has a costume that makes her look like Princess Daisy, it's just a nod to the game series with characters who are exactly alike.
