Lord Boros, The Dominator of the Universe

Name: Boros

Nicknames: Lord Boros, Dominator of the Universe, The Second Strongest Simurian

Gender: Male

Race: Rumelian (Simurian)

Appearance: Unlike most of his fellow Simurians, Boros looks like a very tall cyclops-like humanoid with light-pink, spiky hair and bangs that fell over his face, sharp teeth, pointed ears lined with a row of silver earrings, one large blue eye, a second, equally big eye, the source of his Rolloluca, located on the chest, and light blue skin with dark blue crack-shaped markings that started from his eye and covered most of his body. He wears a set of golden armor with purple markings on his stomach and arms, spikes on the shoulder and forearms and a red orb on the chest, a pair of matching curved boots, a pair of white harem pants, held by a magenta-colored sash with silver-lined purple blades hanging from it.

Personality: Because of his incredible power, Boros is both arrogant and prideful. Driven by his love for battle and his inability to find anyone capable of matching his strength outside of Dabura, he roamed the universe seeking worthy opponents. He was also extremely callous, indifferent to the destruction and loss of life the Kalyan caused. Despite this, he displayed moments of courtesy and respect, particularly around strong fighters like Yuji Itadori. In battle, he has a very cautious and serious behavior, attempting to end fights quickly and make sure his opponent doesn't have any chance to surprise him.

Abilities:

Cursed Energy Reserves: Boros is tied with Dabura in terms of Cursed Energy Reserves, with this amount being one of the reasons he's considered the second strongest Simurian. He also has enough reserves that he can use a Domain Expansion and not have to deal with the burnout, albeit only for some time.

Reverse Cursed Technique:

Boros boasts that the Simurians have the most advanced Reverse Cursed Technique in the universe, with his Reverse Cursed Technique being more advance than Dabura, able to regenerate from attacks that most other sorcerers would be killed by.

Cursed Technique: Cursed Energy Projection

A Cursed Technique that harness his body's cursed energy to fire devastating beams of cursed energy from the eye in his chest, capable of blowing up a building if he wanted to. His attacks had a massive area of effect, and he can also combine energy projection with physical strikes, creating shockwaves and blasts capable of destroying a city.

Extension Technique: Cursed Energy Bullets

An Extension Technique that allows him to condense his cursed energy beams into smaller projectiles that aren't as strong, but are faster than his regular energy beams. This Technique is perfect for if Boros wants to test what an opponent is capable of.

Cursed Technique Reversal: Cursed Energy Absorption:

A Reversal of his Cursed Technique that allows him to refill his cursed energy reserves by grabbing onto someone or something with cursed energy, and taking it from them. This Technique is one Boros doesn't use often, due to him preferring to fight someone without using such 'Underhanded Tactics'

Maximum Technique: Collapsing Star Roaring Cannon

A Maximum Technique that launches a massive beam of energy from his mouth, which is much larger than his average energy beams. The color was also different; instead of being only blue, it had golden tones to it. In order to fire it correctly, Boros has to concentrate, otherwise the attack won't work properly. However, should he concentrate long enough, the attack can easily destroy an entire city in seconds.

Domain Expansion: Meteoric Burst

By doing the Garuda Mudra Hand Gesture, Boros can expand his domain, which takes the form of space, though there seems to be nothing but stars. However, these stars will start firing Cursed Energy beams upon anyone caught in the Domain, with the exception of Boros himself.

Binding Vow:

Through a Binding Vow, Boros can only use 75% of his output so long as the Armor is on his body. The trade off is that should he take it off, or if it's forced off, then he'll be able to use up to 150% of his Cursed Energy Output.
