All experimental content is being left out of the event.
In a sentence that no one likely ever saw coming, LeBron James has been banned from Evo 2022 in MultiVersus.
LeBron and Iron Giant were both added as part of the Open Beta launching over the last several weeks, and both characters are still listed as experimental in-game. Because of that, Player First Games and Warner Bros. Games have decided that players are not allowed to use either character during the $100,000 MultiVersus tournament being hosted at Evo 2022.
In addition to the two newest characters, the recently unlocked Cromulons is also banned for similar reasons.
All of these details were revealed alongside the main tournament rulings for the MultiVersus Evo event, which includes a few other interesting points to note that set it apart from other platform fighters like Super Smash Bros. when it comes to formattingoutside of it being a two-vs-two focus.
This does not set the precedent for all events since tournament organizers are free to decide which characters, stages, and rulesets are eligible for use as long as they are options in the game. But for Evo specifically, the developers want players to use characters who have had their kits mostly finalized and other content not in experimental stages.
