Don't know the contract but could Disney use Inhumans? Not that they should, that series is horrible.
The only update I want is better food in the restaurant, that would be a biggie.
Inhumans isn't part of the 1994 contract, since the contract regarding Disney is only imposed on the specific characters Universal's Islands of Adventure is using. So clearly, the Inhumans isn't licensed for Universal's Islands of Adventure, making it free for WDW to use.
