One of several new Season 3 characters
Killer Instinct continues its reign on the Xbox One and newly minted Windows 10 platform, ushering in a new fighter today. Mira, the sister of Maya, is making an appearance. You can get a good look at her gameplay in the video below with a mirror match that showcases most of her abilities.
As for the remaining characters, General RAAM is basically confirmed from the same (correct) Mira leak, Gargos will hit in May, and Eyedol is rumored to be the last announced Season 3 slot. At that point, the new Killer Instinct would be fully complete in terms of hosting characters from the first two classic titles.
