Kryptonite makes Superman a little tired. Like you taking a little melatonin.
His laser eyes will still cut Batman’s rubber suit in half anytime. Oh & he can make time go backwards by reversing the earths spin when the melatonin wears off (even though we don’t live on a ball) & then he’ll just walk up to Bruce & use his own legs to kick his head in slowly.
Not with his trust bat mirror
