This is the Line up most casual fans are more familiar with.
Baymax is also not as cute in the comics version, he have a more reptilian appearance compared to the Disney version.
Fans are more familiar of this white cuddly Balloon version of Baymax. I can see the MCU version going for this one because of a more mainstream recognition.
Big Hero 6 , Most fans associate it with Disney. They have no idea that it was originally a Marvel Comics IP.Many fans have no idea that this IP was originally from Marvel Comics. The comic book team consists of Asians, and the setting of the story is in Japan. The Pixar version happened in a fictional city called San Fransokyo. The people behind the film omitted the X-men characters.Most likely because their association with Fox back then. Silver Samurai and Sunfire might somehow make it though because Marvel owns X-men again after Disney purchased Fox.
There was a bit of controversy back then because of the Whitewashing of the team. The Original comic-book has an all-Asian lineup. The film version have Caucasian and African American members. Hiro at least remained Asian.
