Boros, also called Lord Boros by his subordinates, was the leader of the Dark Matter Thieves, a group of alien invaders responsible for the destruction of A-City. Like Saitama, Boros faced a self-imposed existential crisis, having become so powerful that no battle thrilled him. His intergalactic travels in search of a worthy opponent led him to Earth, where he was killed by Saitama.

There exists a prophecy. I was once a traveler, exploring the universe, ravaging everything in sight. But I was too strong; eventually, I found there were none left that could face me. I came to know the torment of utter, all-encompassing boredom. Then one day, a great seer told me somewhere on a faraway planet, a being exists who is my match; one who could rekindle my passion for battle.
