Competitions on CHERUB campus are fought under strict Karate rules, but the techniques agents learn for use in the field come from many martial arts disciplines, including judo, kung fu and Thai kick boxing.

Emphasis is placed on developing powerful punches and kicks, especially targeting the weak spots of larger opponents including eyes, fingers and testicles. Most responsible martial arts schools refrain from teaching younger students these techniques because they may be used inappropriately. However, cherubs are frequently placed in dangerous situations and it is vital that they have the most powerful martial arts techniques at their disposal.

Any CHERUB agent who abuses their lethal martial arts skills and hurts someone can expect to be severely punished or even expelled from the organisation.
