No Black Panther at Disneyworld. He’s considered part of the avengers so means Universal gets him east of Mississippi. Guardians and Dr Strange aren’t avengers, so that’s how they can have them at WDW.
Basically the contract is any Avenger and Avenger villain goes to Universal (and this is based on the comics not movies). So that means Iron Man, Spider-Man, Captain America, Hulk, Thor, etc...
