The issue was never "this content was on the disc I am so mad."
It was Ono directly lying to everyone and saying outright "we're not done with the characters yet. so we couldn't fit them into the game. we're not sure how to make them work yet." then a couple days later they were found on the disc, complete and gameplay ready.
