"He doesn't need to scream to transform. He simply is the form."

"Who are you?"

[Just as Xicor raises a hand to finish Vegeta, a portal tears open in the sky. The West Kai drops through it, followed by Gohan and Trunks. The West Kai extends his staff, creating a barrier around Vegeta.]

[A blinding flash of light erupts in the center of the Lookout. Everyone flinches. When the light fades, a tall, green-skinned being with a high-tech staff stands before them. He wears a sleeveless Supreme Kai outfit, but his insignia is the Western Galaxy symbol.]

[The void shatters. Goku’s eyes flash red for a split second—a hint of Ultra Instinct, but unstable, merged with his Saiyan core. A new form begins to emerge.]

"I am the West Supreme Kai. And your father, Trunks? The one you call Vegeta? He's about to make a very costly mistake."

(smiles wider): "Correct. I am the perfect son. The one who will surpass him. And you? You're just the warm-up act before I kill the original."

"His energy just vanished. One moment, Goku was chasing that golden comet. The next... nothing."
