The world of San Fransokyo from "Big Hero 6" will be featured in "Kingdom Hearts 3" along with a dangerous new character — the evil Baymax, who is rumored to debut in the "Big Hero 6" television series next year.

The inclusion of the world in "Kingdom Hearts 3" was first announced last year at the D23 event, although this evil Baymax was revealed much later in a concept art.

The artwork showed Sora aboard the armored Baymax battling a sinister-looking Baymax that wore a black suit reportedly referred to as Heartless. This Baymax is one that fans have not seen before.

The story of this so-called Heartless Baymax will reportedly be revealed first in the "Big Hero 6" TV series early next year before he shows up in "Kingdom Hearts 3."

For the uninitiated, the TV series is set after the events in the movie, which ended with Hiro making a new Baymax when the original sacrificed himself after saving Abigail from the portal.

The original Baymax managed to give Hiro his personality chip, which he used to create a new Baymax. The one left in that portal is believed to be the baddie that fans will see in "Kingdom Hearts 3."

It is said that the original Baymax was corrupted by a new villain, who is expected to be introduced in the "Big Hero 6" TV series, which will premiere in January.

"Kingdom Hearts 3" will be released March at the earliest (although Square Enix is yet to announce an official launch date), which should be enough to establish Heartless Baymax as a villain and one that Sora will encounter in the game.

In other news, a box of the Play Arts Kai action figure for Sora revealed details about the plot of the game. In a nutshell, the protagonist will work on stopping Master Xehanort from starting another Keyblade War.
