AEW television finally aired the long-anticipated reunion of Adam Copeland and Christian Cage. After being rescued by The Rated-R Superstar last month at All In: Texas, The Patriarch returned the favor this week by saving Cope from an ambush by FTR, while also fending off his former stablemates. Now that the two legends are once again set to team together, their old mentor from WWE could potentially sign with the Jacksonville-based promotion and link up with his long-time allies - the veteran in question being Gangrel.Adam Copeland made his return at AEW All In 2025, foiling Nick Wayne, Kip Sabian, and FTR in their attempt at annihilating Christian Cage. The former TNT Champion did not reconcile with his once-best friend immediately, however, and turned his focus on exacting vengeance against Dax Harwood, Cash Wheeler, and their manager Stokely Hathaway. Christian, on the other hand, publicly disowned his "sons," Wayne and Sabian, though the latter duo promptly fired back by destroying Cage with a con-chair-to.This week on AEW Dynamite, The Instant Classic saved Copeland from FTR after The Ultimate Opportunist's match against Stokely. He also fought off Nick Wayne and Kip Sabian alongside Cope and returned the latter's signature weapon, "Spike," which ultimately led to Copeland embracing Cage. The legendary duo is set to finally team up and take on The Prodigy and "Superbad" Sabian at Forbidden Door 2025. Should they find themselves in need of reinforcements, however, Cope and Christian might be joined by their old ally, Gangrel.The self-proclaimed "Pro-Wrestling Vampire" shares history with Copeland and Cage, as the three stars were part of an iconic Attitude Era faction called The Brood in WWE. In fact, Gangrel appeared at AEW Double or Nothing 2024 to help the former Edge retain his TNT Title against Malakai Black. The 56-year-old could sign with All Elite Wrestling and officially reunite with Cope and Christian to help them take down Nick and Kip at Forbidden Door, and eventually FTR as well.Other announcements for AEW x NJPW Forbidden DoorAll Elite Wrestling will host this year's edition of Forbidden Door at The O2 Arena in London later this month.
