Kingdom Hearts 4 is one of gaming's most anticipated JRPG titles, as it begins a new saga in the long-running franchise. Kingdom Hearts 3 brought the series Dark Seeker Saga to an end, as Sora traversed a variety of new and exciting worlds from Disney's more recent animated catalog. Perhaps one of its most unique was San Fransokyo, based on the film Big Hero 6, which marked Kingdom Hearts first dip into a superhero property. However, Big Hero 6s appearance in Kingdom Hearts 3 left little room for other popular superhero titles to be featured. One particular superhero property is long overdue for its own Kingdom Hearts world, and while it wouldn't have made sense for Kingdom Hearts 3, it does for Kingdom Hearts 4.
