Finn Bálor shocks the NXT Universe to its core when he unleashes a brutal attack on Johnny Gargano.

Finn Bálor already upset the balance of power in NXT once this month, causing a seismic shift with his return to the black-and-gold brand.

He did it again Wednesday in even more shocking fashion. 

Bálor arrived to seemingly help even the odds when Tommaso Ciampa and Johnny Gargano confronted The Undisputed ERA, who were fresh off picking the bones of the battered Keith Lee and Dominik Dijakovic after Roderick Strong's successful North American Title defense. 

Standing side-by-side with The Blackheart and Johnny Wrestling, Bálor stunned all in attendance when he instead caught Gargano on the nose with a Pele Kick, leaving The Undisputed ERA to decimate Ciampa four-on-one. Bobby Fish and Kyle O'Reilly held the helpless Ciampa in place for a devastating Last Shot by NXT Champion Adam Cole. 

But all incredulous eyes were locked on Bálor, who wasn't finished. He sent Gargano and the ringside barricade toppling with a thunderous dropkick before punctuating his confounding actions by spiking The Heart and Soul of NXT head-first on the ramp with the 1916 DDT. 

With Bálor once again turning NXT upside down, we're left wondering a simple question — why?
