Any Stories Where the Male Lead Starts Out at the Absolute Peak of Combat Power?

Looking for stories where the male lead is at the very top in terms of combat power, and the female lead isn't a self-sacrificing saint or an idiot.

Invincible from the Start, Unstoppable Throughout the Whole Book

Please don't recommend stories where the male lead acts like a lovesick puppy toward the female lead, as if he's never seen a woman in his life. I really can't stand that.

Looking for books similar to "Undertale: Evil Bones Travel the Multiverse".
