Look, when it comes down to raw cosmic power, Goku's got the universe on a string. The dude can go Ultra Instinct, and we're talking about dodging attacks on a whole different level. Yeah, Doom Slayer's got some serious firepower and the rage of a thousand hells, but Goku's mastered the art of combat like no one else. He shatters solar systems like they're made of glass, while Doom Slayer’s running around blasting demons. Goku's Kamehameha and Spirit Bomb can wipe the floor with anything Doom throws at him, especially since Doom's guard is non-existent. When the dust settles, Goku's standing tall, ready to take on the next challenger. That's cosmic level supremacy right there!
