Think of his cheat as a supercharged version of Saitama from One-Punch Man, but applied to everything.
Infinite Power: He has no limits on his strength, speed, intelligence, or anything else. His potential is endless.
Always Growing: He gets stronger all the time just by existing. When he fights or trains, that growth becomes incredibly fast.
Perfect Control & Immunity: He can use his immense power with perfect precision, so he won't destroy a town by accident. Also, attacks from anyone weaker than him are completely useless against him.
