Ken might be rocking a stylish new 'do, but that coif isn't a source of power the way it is for one of Street Fighter V's newest contenders: Necalli.
He's a mysterious mountain man clad in nothing more than a loincloth, with thick, torso-length hair separated into whip-like tentacles by metal bands. Necalli fights with animal-like ferocity (think Blanka), and he specializes in powerful close-range attacks.
All of Street Fighter V's combatants have new V-Skill and V-Trigger moves, with the former filling up a gauge that allows the player to unleash the latter. In Necalli's case, an explosive ground pound eventually unlocks his "Torrent of Power" V-Trigger, which lets his hair loose in a free-flowing, fire-red mass and puts him into a sort of berserker state, with a whole new set of moves and combos.
Capcom promises to reveal more of Necalli's background before the game launches. His name is also the Aztec word for "battle," so that at least ought to give a pretty good idea of where he hails from. Take a peek at Necalli as he beats the stuffing out of Ken in the reveal trailer up top.
