New mechanic ideas

Have any of you had ideas for new or cool mechanics which to be honest with the state of the game and the style of characters and the amount that have should be in the game. What I said maybe a little confusing but are there any mechanics that would be fun for specific characters or even game modes that would change to combat of the game making it more diverse. Example: if deadpool and Howard the duck and gwenpool(probably Glenpool the most) or she-hulk would be able to affect or fully block sp3s seeing that in the comics they can break the fourth wall. I think majoritively it wouldn't hurt, either doing a special 3 has some damage backlash or any character has a certain effect or probably some full negation from like Glenpool who in comics has crazy 4th wall breaks
