At Extreme Rules in June, Wyatt failed to become number one contender for the Universal Championship in a fatal five-way match, as the match was won by Samoa Joe. After Seth Rollins was unveiled on the cover of "WWE 2K18", Wyatt targeted him and defeated him both at Great Balls of Fire in July and again on the following "Raw". In the following weeks, Wyatt began a feud with Finn Bálor, resulting in a match between the two at SummerSlam in August, where Bálor defeated Wyatt under his "Demon King" persona. Wyatt again lost to Bálor at No Mercy the following month. The two were due to face for the third time at in October, but Wyatt was unable to compete due to an illness concern and was subsequently replaced in the match by AJ Styles, bringing the feud between Wyatt and Bàlor to a quiet end. Wyatt returned on the November 13 episode of "Raw", facing Jason Jordan in a losing effort.
