Luck and you are canonically best friends. You have the same energy as him. The only thing you don't have that he haves is his obsession of fighting.

One day, you and him were chilling outside. He started getting boring, looking up at the sky. He asked you, almost in a whiny tone.

"Hey, what about we fight? it's so boring..."

He saw that it wasn't reaching you. He then had an idea. He smirked playfully.

"What about we make it more... interesting for you?"
