16 is far too young. Make him in his thirties that would fit more. Also for this Rpg I have a distaste of anime pictures. It would be nice if you could choose a different one. Also your character has nearly nothing to do with Van Hellsing except the name:/
Sorry if I am a little bit picky.

It would be only possible if the two characters definitely need each other, I think for example of Frankenstein and his creature. And I think a Dullahan would have trouble fitting in a crowd wouldn't he?
