King Ghidorah is the main antagonist of the 2019 Godzilla vs. Evangelion crossover event at Universal Studios Japan, particularly the ride Godzilla vs. Evangelion: The Real 4-D.
Mysterious lightning storms have appeared across the Kansai Region, believing to have come from cosmic rays. Also, the Mahoroba asteroid probe was destroyed in its descent back to Earth, with the last image captured before the loss of communication showing a massive shadow. Suddenly, Godzilla shows up in Osaka-III, believed to be another Angel and the possible suspect behind the storms. NERV sends the Evangelion units out to stop him. Despite their efforts, Godzilla easily defeats the units before charging his atomic breath. Instead of aiming for the units, Godzilla fires his beam at the sky and a large explosion occurs. The fireball changes shape to the form of a three-headed dragon, revealing the true culprit behind the attacks, King Ghidorah.
With NERV unable to detect Ghidorah's powers, they have the Evangelion units stand back as Godzilla clashes with Ghidorah. Godzilla blasts a beam at Ghidorah, only for it to fly off an invisible force field. Ghidorah uses his electric abilities to levitate buildings from the ground and chuck them at Godzilla. Seeing Godzilla losing the battle, the Evangelion units attempt to distract Ghidorah, only to blasted aside by his electric beams. When Godzilla stands up, Ghidorah attacks him and attempts to kill him by constricting him, only to be thrown off when Godzilla catches him by surprise with lasers from his spines, although this causes Godzilla to temporarily run out of energy.
Fortunately, Godzilla's attack on Ghidorah causes a wound on his chest, with NERV conducting that it is the key to defeating him. Climbing a large building when he flies by it, Unit-02 and Unit-00 grab a hold of Ghidorah's leg, blocking his efforts to blast them off. Supplied with a large red sword from NERV, Unit-01 jumps from Godzilla's tail and the levitated buildings, plunging it straight into Ghidorah's wound. Ghidorah then crashes into the buildings below.
As the unit pilots question each other if they succeeded in defeating Ghidorah, the vile dragon emerged from the rubble standing, albeit severely wounded. He turns his wrath at the motionless Godzilla and blasts him with his electric beam. Godzilla awakes just in time and pushes the beam with his atomic breath. Ultimately, Godzilla's beam overtakes Ghidorah's beam and destroys him in a massive explosion. With his archenemy defeated, Godzilla triumphantly returns to the ocean.
- This Ghidorah is nicknamed "Shin King Ghidorah".
