I haven't played Metroid, but I do know enough about it that it made a pretty awesome series, and this version has to be the SSB Brawl version of the zero suit. It's very nicely done. I happen to agree with most of the guys here, that she is firkin hot as a pony.
Wow, what a cute and cool pony! We all know that if Pinkie Pie were duplicated via zeta radiation, Samus would be contracted to wipe them all out. Very nice coloring on this, by the way, especially with the light against the Zero Suit.
Combining Zero Suit Samus and Ponies is just WOW. There are no words to describe this, but I will try anyways. I love how the blue and yellow contrasts with the darks of the back ground. The hair is very nice too and the eye look like you could get lost in them. Form and expression are true to the character.
