I caught the promo, and Samus Aran (Metroid) will be in this episode. Presumably she'll be a part of the Gaming's Next Top Model sketch.
Is this the very first time she has appeared in animation? I know Mother Brain was the main villain in Captain N and that "Metroid" was a location in the show, but Samus herself only appeared in the tie-in comic books.
In any case, I'm actually tuning in tonight. Hopefully it'll be better than what I've come to expect from this sloppy, amateurish show.
