The Hardy Boyz have found an unusual way back to WWE television, and it isn't by signing a contract with the company; it's via TNA. They are set to return in a little over a week, with one big stipulation.Following the crazy events of the episode of NXT before No Mercy 2025, General Manager Ava has been under a lot of pressure to make big decisions. As a result, she made a massive announcement: On October 7, there will be a show titled "Invasion," where TNA talents will be on NXT television, and they are expected to face each other in a Survivor Series-style clash.As for The Hardy Boyz, the TNA World Tag Team Champions will be taking on the dominant NXT Tag Team Champions, Darkstate, in a title-for-title Winner Take All match.This is WWE's big crossover, and it has been happening slowly. Even with AAA, the Worlds Collide event has presented a huge crossover opportunity. After Ethan Page defeated Tavion Heights at No Mercy, he was confronted by the AAA Latin American Champion, El Hijo de Dr. Wagner Jr.Just recently, Ash by Elegance vacated her Knockouts Championship as she needed to step away for personal reasons, soon after winning it from Jacy Jayne. Now, NXT's Kelani Jordan has won the title, bringing it back to WWE.So perhaps Invasion is where a lot of things are rectified, but for now, it's going to be war between the two brands. Trick Williams is the TNA World Heavyweight Champion, and Mike Santana has been in pursuit of him. Newly-crowned TNA International Champion Frankie Kazarian also expressed his excitement.It's going to be interesting to see how it all plays out, especially as The Hardy Boyz, the two biggest veterans you can imagine, take on the young up-and-comers and the ever-threatening group, The Darkstate. Things are going to get heated.
