Season 2 (Disney +)
- The season was announced before the premiere of the series, marking the first time a show on Disney XD was renewed before it officially aired.
- The series intro for Season 2 contains slight differences from Season 1, such as incorporating Mini-Max in some shots, using different villains, including a scene of Baymax in overdrive mode facing off against a mutant Orso Knox, and featuring the team members just before the title card in their new, upgraded armors.
- The end credits were also changed to include chibi versions of characters rather than having Baymax's head.
