Pollux Totmann

Pollux Totmann (デッドマン・ポルックス, Deddoman Porukkusu), also simply called Deadman by some, is a Mage and a member of Hydra Head. He is known mainly for his use of Incantation Magic.

Magic and Abilities
Incantation Magic: is a Caster Type Magic that uses incantations to cause various effects. Many of Pollux's spells are in Latin.
 *  Vi et armis invictus maneo (私は腕の力によって征服されないまま, Watashi wa ude no chikara ni yotte seifuku sa renai mama): an Incantation meaning "Through/by the force of arms I remain unconquered." this protects Pollux from Magic and Attacks that rely on/use any sort of weapon (swords, guns etc). This Incantation's effect lasts for 10 minutes, but prevents Pollux from being able to use any other Incantations for that time.
 * Invictus maneo (残るひるまない, Nokoru hirumanai): a shorter version of the above Incantion. It can be cast faster, but only works for a single attack.

Trivia

 * Pollux as a name is the Roman form of Latin Polydeuces (Greek Polydeukes), meaning "very sweet." In mythology, Castor ("beaver") and Pollux are the twin sons of Jupiter and Leda and are known as the Dioskouroi ("boys of Zeus") and the Gemini twins.
 * Totmann is literally German for "Deadman"
 * So his name basically means "Very Sweet Deadman"
