In case you're wondering, thats Wil from Mushromm Kingdom Hearts in the first frame. The other thing is Flaahgra from Metroid Prime. it's kind of an inside joke, so don't ask. Unless you're really nosy, then go ahead.
Metroid, Samus Aran, Space Pirates, and all that other stuff are properties of Nintendo. Contra is a property of Konami. All other characters are property of their respective owners. Pretty much everything else is property of me, unless specifically noted otherwise.
