They did an awesome job porting Iori to this game. Also you can tell Iori is one of LG's favorite KoF characters by how flawless he plays with him here.
He is so well loved that Sakurai thinks he was the coolest character that he ever saw back then not to mention being no 1 in polls back then. He is just that perfect.
Iori is rather a random choice for guest, I mean if SNK wants to have a character they own in this game they could have picked someone from Samurai Showdown or Last Blade
They likely picked him because of one of the characters of this game is a guest in SNK Heroines not to mention he is a top favorite character among fans and even some video game developers like Sakurai of Smash fame.
Wait hold up! Square Enix made this game and they add a character from KOF/SNK and its one of the most badass characters in KOF!? Hell yeah! Iori is the best!🌙💜🔥
