As the battle begins, Goku and Vegeta immediately fly towards Asgore. Asgore responds by looking at them and saying "you know how it is", releasing a barrage of blue slashes from his trident. Goku and Vegeta easily dodge them, fly towards Asgore and punch him in the face, causing him to stagger back. Asgore recovers and rushes towards Goku, stabbing him in the gut and slamming him down to the ground. However, before Asgore can do any more damage, Vegeta kicks him in the back, sending him flying away. Asgore gets up and stabs the ground with his trident, unleashing a barrage of fireballs that Goku and Vegeta evade by flying higher in the air. With Asgore distracted by his own attack, Goku turns Super Saiyan and punches him in the face with tremendous force, sending him hurtling back. But before they can follow up with another attack, Asgore moves his hand and creates a circle of fireballs that begins to close in rapidly around Goku and Vegeta. Thinking quickly, Vegeta transforms into Super Vegeta and kicks Goku towards Asgore, who is caught off guard by the unexpected attack. Goku seizes the opportunity and fires a powerful Kamehameha which sends Asgore flying into the sky. But Asgore is not done yet. He transforms into a Super Saiyan God, his eyes glowing with power, and kicks Goku even higher into the sky. Goku responds by turning into Super Saiyan Blue and slamming into Asgore with a flurry of punches and kicks, while Vegeta charges up his Final Flash attack. Asgore takes a few more hits from Goku's attacks, but manages to dodge Vegeta's massive blast by teleporting behind Goku. Utilizing his trident, Asgore stabs Goku in the back, causing him to scream in pain and fall to the ground. But just as Asgore is about to finish off Goku, Vegeta appears out of nowhere and delivers a devastating kick to Asgore's face, sending him flying towards the ground. By working together, Goku and Vegeta have finally defeated Asgore.
