TNA has officially locked in the full lineup for this Sunday’s Rebellion pay-per-view event in Los Angeles, and a familiar face from WWE’s Hall of Fame will be stepping into the spotlight.

Sean Waltman is set to appear at Rebellion, joining forces with The Rascalz—Trey Miguel and Zachary Wentz—alongside Ace Austin as their corner man. The trio will go head-to-head with The System’s Brian Myers, Eddie Edwards, and JDC. Waltman's involvement was confirmed during Thursday’s episode of Impact after Miguel reached out to Waltman in a backstage segment to bring him in for backup on Sunday.

Another major bout added to the event is Steve Maclin’s first defense of the TNA International Championship. Eric Young issued the challenge to Maclin after last week’s Unbreakable special went off the air, and the match is now officially part of the main card.

Additionally, a six-woman tag team match featuring NXT's Fatal Influence—Fallon Henley, Jacy Jayne, and Jazmyn Nyx—against Rosemary, Lei Ying Lee, and Xia Brookside will air during the Countdown to Rebellion pre-show.
