WWF Invasion

WWF Invasion (also stylized as InVasion) was a 2001 professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It took place on July 22, 2001, at the Gund Arena in Cleveland, Ohio. The event had been promoted as the fourth Fully Loaded at the preceding King of the Ring event, but WWF changed it to Invasion in May. Invasion was the first pay-per-view to feature the ongoing Invasion storyline, which featured wrestlers from the WWF taking on The Coalition, a combined force of wrestlers from the former World Championship Wrestling (WCW) and Extreme Championship Wrestling (ECW) promotions, later known as The Alliance.

The main event, dubbed the "Inaugural Brawl", was a five-on-five tag team match between Team WWF (Stone Cold Steve Austin, Kurt Angle, Chris Jericho, Kane, and The Undertaker) and Team WCW/ECW (Diamond Dallas Page, Booker T, Rhyno, Bubba Ray Dudley, and D-Von Dudley), which Team WCW/ECW won after Austin betrayed Team WWF. The other main match was a singles match for the WWF Hardcore Championship between Rob Van Dam and Jeff Hardy, which Van Dam won. With a buyrate of 775,000, the event is the highest-grossing non-WrestleMania pay-per-view in WWE history.

Following the conclusion of the storyline, instead of bringing back Fully Loaded, the event's July slot was given to Vengeance in 2002 when Armageddon returned that year; Vengeance temporarily replaced Armageddon in December 2001 due to the September 11 attacks. The Invasion name was set to return in October 2025 for an event between WWE's NXT brand and partner promotion Total Nonstop Action Wrestling (TNA), but due to controversy with Israel and the October 7 attacks in 2023, the event was changed to NXT vs. TNA Showdown.
