Claw

Claw was a criminal organisation composed entirely of Espers. They recruited Espers to strengthen themselves and planned to overthrow the world government. The organisation was founded and led by Touichirou Suzuki, but is now believed to be defunct after the latter's defeat.

Scar
"Scar" was a special cadre of the organisation, composed of particularly powerful Espers. When a member of Claw defied and/or challenged the boss, a wound was placed on them; this mark was representative of the boss acknowledging the recipient's skills and thus they became a member of "Scar".

However, this was proven to be false by Shimazaki, stating that these scars meant "cross"; the symbol of disposable and useless products. They would be disposed of once world domination was completed. There were many branches stationed throughout the countries, led by 'Branch Representatives' that were the most powerful in their own branches. There were 20 branches in total, with 19 of the Branch Representatives defeated by Teruki and Takeuchi whilst the 7th Branch Representative was defeated by Shou.

Claw HQ
The most important branch in the structure of Claw, composed of nameless subordinates, Super 5 and the boss. Foreign mercenaries were once part of Claw but they were annihilated by the Super 5 after Joseph, an assassin sent by the World Government, led a riot and tried to subdue Touichirou Suzuki and Katsuya Serizawa before being disposed by the latter. The 600 soldier army were shown previously to be commoners, as said by Matsuo, but after Suzuki imbued them with his power, large groups were powerful enough to collapse buildings without breaking a sweat. Fukuda, Higashio and Ootsuki were also once part of the HQ but joined Shou against the resistance against the boss.

Super 5
The most powerful cadre of Claw, they were the only ones the boss 'trusted' and true cadres. They are immensely powerful, described as having an unusual 'aura' as said by Ritsu. It is said by Touichirou that Serizawa was the most powerful cadre but was considered weak due to his soft nature. Shimazaki thought he was the most powerful, right after the boss but this is proven wrong. These cadres, unlike Scar members, can take on large groups of espers. The five members have unique and weird powers, namely:
 * Katsuya Serizawa: powerful psychokinesis, capable of withstanding and escaping Joseph's smoke hindering "White Noise". He can imbue energy through his umbrella, serving both as defence and offence.
 * Shimazaki: having the most abilities, teleportation, free control over his dense power membrane and reading his enemies movements, he is one of the few people who can use two abilities simultaneously.
 * Hatori: the weakest amongst the cadre in terms of battle power, but the most useful in terms of support and influence. Technology manipulation, even he himself isn't sure how it works. With ease, he was able to hack the national program with just a projector.
 * Shibata: a large individual with muscle mass manipulation and so far the tallest character in the series.
 * Minegishi: the plant manipulator. His plants can suck the life out of people, an ability he often uses in combat.
