Whee, animation! Two whole frames worth! If you never played the original Metroid, you suck Samus would change colors when you switched back and forth between missle mode and gun mode.
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.
