Hungrybox is the guy standing and playing Jigglypuff. He came in 2nd last Evo.
Armada is the Swedish guy sitting down playing Fox (though used to play Peach.) His technical game is insane.
Both are one of the "Five Gods of Melee," the others being PPMD (eliminated by Hbox), Mango (won the last two Evos, also eliminated by Hbox), and Mew2king (who is not at Evo due to hand problems.)
