Baymax is a healthcare robot featured in the Disney animated film Big Hero 6. He is a large, inflatable robot with a marshmallow-like exterior and a built-in healthcare database. Baymax is designed to heal and protect people, and he is always there to lend a helping hand. Baymax was created by Hiro Hamada, a young robotics prodigy. Hiro built Baymax to help him take care of his sick grandmother, but Baymax quickly became more than just a healthcare robot. A fanart cute cursor with Big Hero 6 Baymax and Heart.
