Brock Lesnar's WWE return could shake the entire landscape of the Stamford-based promotion. The Beast Incarnate was last seen at SummerSlam 2023, and since then, he has yet to resurface on WWE television.The fans of the veteran grappler are still hoping that one day, he will return to the sports entertainment juggernaut. As we head towards SummerSlam 2025, there is a chance that Brock Lesnar could return at The Biggest Party of The Summer and cost Dominik Mysterio the IC Title match.The Judgment Day member is set to defend his Intercontinental Championship against AJ Styles at SummerSlam.

This could be done by having the legendary star make a shocking comeback at the upcoming premium live event and cost Dominik the Intercontinental Title.This will lead to The Phenomenal One becoming the new IC Champion, and leave the field open for The Beast Incarnate to challenge for a title he has never won in his career. On the flip side, Triple H can book a Dom vs. Brock match to continue in the vein of previous plans at a PLE after SummerSlam.Recently, a new update broke on Lesnar when retired UFC star Daniel Cormier revealed that The Beast Incarnate was banned from WWE. Nevertheless, the current scenario is that the 48-year-old star can return to the Stamford-based promotion only after he gets legal clearance from the TKO team.Hence, this speculation needs to be taken accordingly.Brock Lesnar spotted, looking massive, ahead of SummerSlamJust a few days back, The Beast Incarnate was spotted, with the star looking jacked.
