UPDATE: Capcom has officially confirmed Eleven as a DLC character for Street Fighter 5.
Eleven is a character who morphs into any of the other characters in the game before the match starts. It's a random select character, in essence, like Mokujin in Tekken - and a pick designed for people to show off with. Check Eleven out in the video below:
Eleven is a bonus DLC character and not the fifth unannounced character of the game's fifth and final character pass. Eleven arrives alongside Dan on 22nd February as a bonus with a purchase of one of the two season five passes: the new premium pass, which costs $39.99, or the standard character pass, which costs $24.99.
