I always liked Metroid, something that has been cemented with games like Super Smash Brothers Melee and Metroid Prime 1 & 2. I love it when Nintendo successfully reinvents the classics. They haven't had the chance to do it often, but it works. Anyway, This picture is based on the idea that the Chozo (the Aliens who originally blessed Samus with her Power Suit) might have left more powerful suits for her to discover. Bigger arm cannon, missile launchers in her shoulders, stuff like that. A few steps from a full mech, heh.
