keep dreaming bro
The designs in this link almost look like they were supposed to be a Shoto version of K9999 and a mannish looking Kula with being hugged by a ghost.
And honestly, I am not surprised, I mean the purposely had him run around and fight with a belt around his knees for about 10 years.
These images are all listed as “rough sketches”, including the characters who are in it. This, coupled with the fact that there are old costumes for some chars who got costume changes, shows that this was from an early phase before characters actually went into development. These were probably just ideas being batted around for new characters who eventually got scrapped.
Most of them don’t even have names, they’re just listed as stuff like “new female character”.
So no, these are not brand new kof13 chars revealed.
Also about the boss section, I just looked at it quickly and it’s hard to read. But it basically says those are sketches for some boss character ideas that didn’t make it into the game. There’s none in the game but they had some ideas, stuff like that. The guy on the left, from my understanding, was going to be the main boss, and the ones up at the top/right are ideas for midbosses.
