As predicted by a character leak months ago, Street Fighter V's last DLC character of Season 2 (following Akuma, Kolin, Ed, Abigail, and Menat) is Zeku, Guy's former master. He's got lots of flips and his kick specials seem to have a good amount of range.
But the craziest part of his repertoire is his V-Skill/V-Trigger. It makes him younger (and looking like a straight riff of Capcom's Strider Hiryu), and gives him a few more special options. He's going to be fun to play around with.
Zeku will be available October 24th.
