Brock Lesnar made a shocking return at SummerSlam 2025, attacking John Cena after his victory over Cody Rhodes. Lesnar's motives remain unclear, leaving fans speculating about his next move and a potential feud with Cena.

There was much controversy around Lesnar's return, with WWE Chief Content Officer Paul Levesque saying that Brock's return was Cena's idea, followed by Cena saying it was WWE's idea, and finally Levesque backtracking and saying they made the overture to Lesnar, who was cleared by WWE legal around a month before SummerSlam.
