Boros

Lord Boros is the leader of the Dark Matter Thieves, a group of alien invaders who attacked A-City.

Appearance
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.

Personality
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.

History
20 years before the start of the series, while Boros was laying waste throughout the universe looking for an opponent that would be able to stand against him, he met a prophet that revealed to him that in a far off planet he would finally find a strong opponent that would be able to fight on par with him giving Boros the enjoyable fight that he had always desired.

S-Class Hero Arc
Boros appears with his spaceship in A-City commanding a mysterious group of alien invaders and, without an apparent reason, he completely destroys the city with the exception of the Heroes Association's headquarters that resisted the damage. Saitama, who was in the building, then broke into the spaceship and effortlessly eliminated first Gloryverse and then Geluganshp, two of Boros' top subordinates, much to his surprise. Face to face with Saitama, Boros starts explaining him that he attacked them because of a prophecy that said that here he would find a worthy opponent. Saitama, angered, punched Boros with strength saying that he destroyed A-City for such a stupid reason, but unexpectedly Boros survived Saitama's lethal punch and with his armor destroyed he unleashed his true strength and prepares to fight a surprised Saitama, going all out. During the battle Boros hit Saitama with everything he's got, included his trump card: the "Meteoric Burst" ability, and without caring for his starship he attacks Saitama continuosly before he can even react punching him all the way to the moon. Returned with a super jump from the moon Saitama begin the counter-attack hitting Boros with barrages of punches, but despite being reduced almost into pieces Boros' regenerative abilities are so strong that he recovers almost immediatly. Seeing that Saitama have still stregth Boros decide to use his other trump card: the "Planet Buster Roar Cannon", a beam of energy so strong that can wipe out an entire planet, but before the beam could hit the planet Saitama uses his own trump card: the "Serious Punch", that repel Boros' beam and critically damages him. Defeated, incapable of regenerate for the heavy damage but still conscious, Boros compliments to Saitama for the splendid battle and surprises him one last time revealing that he knew that during their fight Saitama never showned his full potential, saying that Saitama his way too strong and that it looks like prophecies can't be trusted after all. After saying this Boros dies while a victorious Saitama leaves the ruins of the starship.

Abilities
As the leader of the invading force of aliens, it's safe to assume that Boros is extremely 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.


 * Immense Durability: Boros is shown to be amazingly resilient, to the point of being the first opponent of Saitama's to survive after being hit directly by one of his punches despite having his full powers sealed by his armor.


 * Regeneration: Boros has been shown to regrow an arm in seconds just by concentrating on it. Later when hit continuosly by Saitama he was able to regenerate any part of his body incredibly quickly. However Boros' regeneration abilities have a limit of maximum continuous damage beyond with Boros wouldn't be able to regenerate.


 * Power Detection: Boros appears to be able to sense peoples' energy levels, which manifests itself as an aura around said person. Thanks to this he can sense the strenght of his opponents.


 * Energy Projection: Boros has been shown to be able to direct large blasts of energy from the eye in his chest with great destructive power.


 * Released Form: Boros wears an ornate suit of armor that is designed to keep his immense powers in check. When the armor is removed his body becomes black and spiky and begins to glow from the released energy.

Techniques

 * Trump Cards: Boros has several techniques which he uses when he wants to finish a fight quickly or thoroughly destroy an opponent.
 * Meteoric Burst:  It is Boros' trump card which he resorts to when he wishes to settle a fight quickly. He uses his latent energy to boost his body to release speed and power beyond its limit, at the cost of putting immense burden on his body. This also causes his body to start glowing white. In this form Boros' punch had enough power to send Saitama to the moon.
 * Planet Buster Roar Cannon: While in his meteoric burst form, Boros can launch a massive beam of energy from his mouth. Boros states that it can wipe out the face of a planet, but before it can hit the surface of the planet Saitama was able to repel it making the beam only cut the planet's atmosphere.

Trivia

 * It is worth noting that he is the first opponent of Saitama that survived after getting one-punched, much to Saitama's surprise. (Excluding characters like Sonic and the Tanktop siblings, who he didn't mean to kill.) However it's later revealed by Boros that Saitama "didn't bare his fangs at all".
