Megumu Koyama

Megumu Koyama (誇山恵, Koyama Megumu) is an esper and a former member of Claw. He was part of the upper echelon called "Scar".

Appearance
Koyama has a mohawk mirrored by a goatee, a diagonal scar across the centre of his face, a lip ring, three earrings in each ear, and a blatant lack of eyebrows. He is normally seen wearing a hoodie with a black tank top underneath.

As of chapter 100.7, Koyama now lacks his significant piercings and goatee, and having black hair instead. Unknown if it's dyed or his natural hair colour. Like Sakurai, he wears the uniform of the convenience store he is employed at, Smile Mart.

Personality
Koyama is prideful, reckless and easily frustrated. He has no qualms about using violence against kids and is a self-proclaimed "asshole", who will brutalize even opponents who willingly submit to him. It's possible that this is his ruthless way of making others learn to never do evil, at least in regards to commoners. He is prideful, and insists that he did not "lose" against Mob, even though he fled the scene rather than risking facing ???% Mob. He is willing to fight dirty, using cheap shots and knockout gas to try and defeat opponents that his sheer power can't overwhelm.

He showcases being naive from time to time, and often overlooks things or tries to avoid the scenario that's too difficult for him.

However later on his personality changes to reveal that he's willing enough to work with old enemies against a common opponent.

On chapter 100.7, it is revealed that he finally got his act together. He became a more honest worker, prioritizing his customer's satisfaction over the profits of the store, much to Sakurai's disapproval. Also, for the sake of protecting their jobs, Koyama is willing to fight against ???% Mob unlike before and working together with Sakurai instead of being hardheaded in fighting alone to prove his worth.

Big Cleanup Arc
Koyama was first seen when he was assigned by Claw to capture Mob but ended up mistakenly targeting Ritsu, attacking him during a scuffle between middle schools in an alley. When he got his hands on Ritsu, Mob intervened and the two had a brutal battle where Mob ended up going 100% Animosity due to Koyama's callous and violent treatment of Ritsu and the other students. Koyama sustained heavy damage in the beatdown that ensued. Before Mob could defeat him, however, he used Sakurai's cursed perfume to put him to sleep, then quickly escaped with Ritsu.

7th Division Arc
Later, he encountered Mob at the base of Claw's 7th Division, standing in their way. Mob, more ready this time, instigated a completely one-sided battle in which Koyama was quickly thrashed and defeated.

World Domination Arc
After the fall of the 7th Division at the hands of Reigen and the others Koyama is seen to have left Claw and become a normal citizen. He reappears with the other former Scar members decide to fight against Claw's bid to take over Seasoning City, and is present at the meeting asking Reigen and the others for their help.

Koyama is part of the group that is sent to infiltrate the Claw-occupied Culture Tower via the sewer. Their progress is halted when Shimazaki appears, forcing them to quickly escape.

Koyama later appears with Teruki and the rest of Scar to back up Ritsu when he's cornered, again by Shimazaki. Koyama is the first one able to land a hit, throwing a manhole cover at him while he's distracted. Teru and Scar all attack Shimazaki at the same time, but are overwhelmed by his incredible power. Shimazaki explains that Scar was the rank of those marked for failure rather than of Claw's advanced, enraging Koyama. Eventually Teru figures out how to predict Shimazaki's teleportation and they gain the upper hand for a moment, even being able to land some powerful hits. However, Shimazaki awakens his ultimate ability, Mind's Eye, and quickly defeats them all in a second. Thankfully, Shimazaki is defeated by a passing Reigen and the battle ends. Koyama plans on attacking the Culture Tower with Mob, but he forces them all to wait and recover from their fight with Shimazaki.

Koyama later watches with the rest of the heroes as Mob battles Toichiro Suzuki atop the Culture Tower.

???% Arc
Koyama and Sakurai attempt to fight Mob's ???% mode, but they can't do any serious damage. They step back when Toichiro appears.

Powers & Abilities
Koyama specializes in using his psychic powers in conjunction with brutal hand-to-hand combat, enhancing his blows using telekinesis. He is also capable of summoning defensive barriers like most psychics. He is shown to be a skilled fighter even when not using any psychic techniques as well. His psychic aura takes on a reddish color with a purple border around the edges.

Notes & Trivia

 * He almost threw up when Shigeo made his and Sakurai's car fly, suggesting he may suffer from motion sickness.
 * Oddly enough, his name is an oxymoron to his personality (Megumu meaning 'kindness' to his 'asshole' behaviour, although this seemed to have changed recently).

Quotes

 * "Hey you, good-for-nothing. What's with that rebellious stare? ... Grovel, and apologize to me. We're reviewing the scene you were playing out earlier. I know! All of you should grovel! Will this make you a little more willing? If you don't grovel, I'll kill all of you."
 * "Cry."
 * "That's a wise decision, but I'm an asshole."
