I mean, Goku has hax. It’s just not balls to the wall, Pre-Crisis DC Comics Hax. Like, Goku can deconstruct matter with a point, turning it to Dust. He can erase mind, body, and soul from existence across time, (albeit imperfectly), by focusing his energy and directing the raw intent to destroy. He can stop you in your tracks, ceasing all of your motion, with a mere gesture. He can absorb energy, making the strength of others his own. He can grant energy, bestowing you with his power. With but a glance he can derive your combat skills, create counter-techniques, and perfectly mimic your abilities. With but a thought he can transport himself across space and time, traveling across the galaxy and dimensions. With naught but intent, he can link to the minds he so chooses.
It’s just not something incredibly complex and OP.
