A former WWE Superstar promised to put a final nail in the coffin after NXT General Manager, Ava, made a massive announcement about October 7, and it was a chilling warning.Lately, on WWE NXT, there has been a huge invasion with TNA superstars appearing on the brand. While the NXT-TNA partnership isn't exactly a secret, things have taken an ugly turn, with TNA talent believing they are the superior brand and feeling disrespected. With two WWE stars holding the top TNA titles (Trick Williams as World Champion, Kelani Jordan as Knockouts Champion), it's understandable why they feel that way.Ava announced that on October 7, there will be a big show titled "Invasion," where NXT and TNA stars will go head-to-head. Following this, former WWE star and current TNA star Mustafa Ali tweeted, vowing to put the final nail in the coffin in this war."Let it be known to friend and foe alike, we did not start this fight. But we will continue it Tuesday and put the final nail in the coffin of this war at Invasion. @WWENXT."Check out his tweet below:One of the other big matches that Ava announced was The Hardy Boyz vs. DarkState, with a title-for-title, Winner-Takes-All stipulation. It's going to be huge, and it'll also be interesting to see what Mustafa Ali does.This Tuesday, during the episode of NXT after No Mercy 2025, the two authority figures of WWE and TNA will sit down to finalize their respective teams. Aside from the aforementioned Hardy Boyz-DarkState match, Ava noted there will be two Survivor Series-style matches.It will be interesting to see how all of this plays out, and so far, WWE stars have seemingly dominated those in TNA. That's why two WWE stars hold TNA titles and not vice versa.That said, there could be a big change in the tide at Invasion if things go TNA's way, and expect Mustafa Ali to be a big part of that if it does.
