Characters from the Disney Animation film based on the Marvel comic, Big Hero 6, will be appearing in Disney parks starting this fall. Hiro and the inflatable robot, Baymax, will be meeting and greeting fans before the film comes to theaters November 7th.
An issue with every Marvel film going forward will be its presence in the east coast parks. Through a poorly thought through deal many years ago, the rights to Marvel characters in theme parks belongs to Universal. Disney has found some ways around that before. I guess the Big Hero 6 characters are not included with the Universal and Marvel deal or Disney just doesn't care anymore. Whatever the case, meeting Baymax does sound pretty cool.
