Post Season 6
The resetting of the universe created multiple issues within the timeline that required the moderation of an ancient order called The Time Jannies to correct lest it causes the brand new universe to break due to a paradox. One of these events that nearly spelled doom to the timeline was HUNK forcing Tohya into a rematch to make sure that Kojima's plans come to fruition which would prevent the Three Kings from ever rising up to power again. Aware of how strong a wrestler HUNK is, The Time Jannies sent their specialist in the wrestling field, Brock Lesnar, in to interfere with the match to make sure that Tohya would win. Brock, knowing how the business worked, knew of a loophole around the rules. Because of the match having DQ's on, any interference will automatically disqualify someone and give their opponent a point in Iron Man matches.

With this knowledge in hand, he hatched a plan to make sure Tohya won via doing a run in during their match to "help out" HUNK. After his run in, The ref disqualified Brock for his actions and ordered him to leave. Ignoring the Ref's order, He proceded to attack Tohya multiple times which would add a point to Tohya's score, while denying HUNK any points. He sometimes would hit HUNK for a laugh too, not caring about who he attacked as long as Tohya won the match. By the end of the match Tohya was given 53 points via HUNK getting disqualified and HUNK had only gotten 3 via pins. The timeline continued on as usual and Kojima was defeated yet again.

And just like how he appeared, he vanished before he could be confronted.
