Mickey mouse is now copyright free, pluto is in two weeks, then pretty much the whole roster by 2030 https://michelsonip.com/news/disney-characters-in-the-public...
The "modern" Mickey Mouse will be at the public domain in about five years.

Scroll down on this page[0] and you'll see the different Mickeys and most of them are not under copyright. You got Steamboat Whillie + gloves but no Fantasia Mickey or later. Definitely no red-pants version.
Unsurprisingly Disney knows what they're doing and they have 95 years to modify a character's looks (and how the public imagines that character) before it enters public domain.
