Who was the guy attacking yi at the project: overdrive video?

I asked a few buddies of mine and we started brainstorming on who it could be but in the end we just couldn't think of any champ that resembles him so we just left it at that. Then a few days later i let my imagination loose and thought... What if what yi is seeing in his memories are not actually his memories but someone else's who already has a project skin and what if that someone is yasuo. This is just a theory but what if what yi is seeing is a reanimated version of yone. Some might call me crazy but i came to this conclusion after i looked up yone and heres what i found... http://leagueoflegends.wikia.com/wiki/User_blog:V0ldek/Yone,_the_Death's_Debtor_AKA_Yasuo's_brother

If you scroll to the bottom to the lore it mentions how yone was revived for one purpose and it was to kill his brother for revenge. it also mentions how yone went on a rampage killing everyone and looking for Yasuo. It makes sense to me because the village was burning and an unidentified man was killing everyone. Please guys if you think this makes sense tell me so i know im not just going crazy. Ty
