Lord Boros
Lord Boros is a slim, cyclopean alien with lightly colored spiky hair and pointed ears. He wears an ornate suit of armor along with a white cape. Thanks to his amazing powers Boros is both arrogant and prideful. Due to his love of battles and inability to find any opponent who has been able to match him in power, he roams the galaxy looking for worthy opponents. As the leader of the invading force of aliens (Dark Matter Thieves), it can be assumed that Boros is very powerful. According to Boros, as an adaptation to living on a planet that has harsh climates, his species has developed the greatest regenerative ability in the entire universe. He claims that in particular, his regeneration, physical ability and latent energy far surpasses others. (Source: One Punch-Man Wiki)
