Blitzwing (TFAnimated) and the Susuwatari, who are the little soot creatures from Spirited Away. Ignore the size problem. They are so cute!
I don't know, it seemed like it would be a good mix. They remind me of each other. And I think RandomBlitz sees them as some sort of kin.
EDIT: The pic seemed flat, so I added Blitz some ambient light (in red tones, to separate him from the blue bg), and more highlights. I think it's better now. The link bellow has the original colors.

No susuwatari (where you can appreciate the sexiness of his pose)- [link]
