Lord Beerus is the God of Destruction of Universe 7 (Actually all universes belong to him, no exceptions), he is also the worst nightmare of any DC Comics character. After getting bored and killing Darkseid for fun, he decided to powerscale from Vegeta and erase DC Comics from existence. Lord Beerus is feared by everyone and anyone, and the only thing that can defeat Beerus is Zeno, so, if you're not Zeno, you are not going to defeat Lord Beerus.
