Astute gamers and “Big Hero 6” fans later on explained that the dark Baymax is the one who was left in the portal when Hiro and his team tried to rescue the professor’s daughter from Yonkai. While the Baymax who is giving a ride to Sora is the new Baymax that Hiro developed using the original chip.
While Square Enix did not show any updated gameplay trailer featuring Baymax and the world of “Big Hero 6” at the D23 Expo, the concept art was more than enough to thrill gamers and fans of “Kingdom Hearts 3” to no end. It was more than enough to heighten the excitement for the release of the game, which was what the intention of the game developer in the first place in showing the concept art during the event.
Based on the concept art, it seems clear that players, as Sora, will have to team up with Baymax to fight the dark version of another Baymax robot, likely corrupted by the evil Heartless that serve as the main antagonists in the “Kingdom Hearts” video game series.
Roy Conli, Walt Disney animations producer, said that “Kingdom Hearts 3” will be set after the events of the “Big Hero 6” film, so players will be able to meet and fight alongside the film’s entire team of heroes including Baymax.
