Kōsa Besakku

**Kōsa Besakku** (コサベサック *Besakku Kōsa*) is a major antagonist and was a member of the League of Villains, affiliated with the Vanguard Action Squad. He and the rest of his team serve as the primary antagonists of the series.

He later became one of the nine lieutenants of the Paranormal Liberation Front, an organization formed from the remnants of the League and the Meta Liberation Army.

## Appearance

Kōsa is a fairly tall, pale young man of a slim, somewhat-lanky build, described to be in his early twenties. He has perfect, black hair that point neatly upward around his head, hanging low over his right eye, which are thin, turquoise in color, and heavily lidded.

His facial features include mysterious purple eyes with a dark stare, and a sharp chin to improve his looks. In his first appearance, he wears a white button shirt, black turtle neck shirt, neat collar, and brushed angles.

## Personality

Kōsa is often perceived as deceiving, cunning, sly, unpredictable and cruel. While rather crude and violent, he is actually cautious, somewhat showing his mischievous personality to his teammates or people. Overall, Kōsa is a highly enigmatic individual who doesn't feel empathy for people, preferring to do things alone and in his own way. He also gives off the impression of knowing more about certain people than he lets on.

Despite his usual expressionless behavior, Kōsa finds joy in establishing himself as a villain fighting against what he believes to be false heroes, an ideology proposed by his apparent inspiration, Kage. Kōsa is dedicated to Tomura and Kage's mission and desires to destroy superhuman society, sharing his belief that one person with the necessary conviction can do so. He appears to share Kage's sentiment that Heroes are hypocritical and unworthy of their title, but unlike Kage, he does not seem to seek a society with better heroes.

Kōsa has a way of expressing his joy, simply manipulating them into fear. Very pragmatic in battle, he is rather savvy about how heroes operate and will exploit their natural tendency to rescue others. He's not afraid of causing collateral destruction, rarely holding back, even if it puts his allies at risk.

Kōsa can sometimes be moody. An example is when Fifty Percent questions about his family which results in him snapping.

## Overall Abilities

Kōsa is a highly capable and dangerous villain, being one of the strongest members of the League of Villains' Vanguard Action Squad, as well as its de facto leader. Kōsa also has an effective handle on his powerful, yet hazardous Quirk, Vantablack, which not only grants him control over dark energy that are strong, but also proficient wide-range capabilities. Kōsa mainly uses dark tendrils to trap his opponents, making it easier to seal them in one place. Kōsa, primarily fights from a distance, manipulating darkness, generating overpowered attacks, and releasing bursts of tendrils when at close range. His basic offense is using the brute force of his Quirk to overwhelm his enemies. Defensively, Kōsa can seal away attacks and even generate enough darkness to form massive walls of dark energy to surround his targets. With this skill and power, he can incinerate an entire group of opponents in mere seconds. Overall, Kōsa has the power and ingenuity to contend with a multitude of adversaries who outnumber him.

During the fight with Dice Roll, Kōsa easily toys with him and uses his tendrils to his advantage, easily trapping him in the process. With the assistance of his dark energy combining with his tendrils, he was capable of overpowering and landing certain abilities on Dice Roll in Ichigo Forest.

**Keen Intellect**: Kōsa has shown to be a rather astute and strategic villain. Coupled with good judgment, Kōsa is also very observant of everything around him, whether he's reading someone's intentions, or weaknesses; he then toys around with them. When he first met Kage Mizuki, he was somewhat observant but after a while decided to help her in any way possible.

Kōsa is also known for psychologically engaging enemies, questioning their motives and morality during combat. This is an entirely tactical maneuver for buying time since it complements Kōsa's weakness of the sun gaining over his dark energy.

### Quirk
