Hammer

해머 / ハマー

Hammer is a modified human and a member of the Union's special forces unit known as DA-5.
Although he possesses violent tendencies nearly on par with Shark's (though he never expresses them facially), he is logical enough to avoid trouble and can exploit situations to his advantage, no matter how cowardly it may seem. Even though he is arrogant about his strength, he also accepts defeat when facing a stronger opponent in order to survive. He does not hesitate to take hostages or harm even females. However, to his misfortune, when battling Seira, he believes that since she is a female, she will be an easy defeat. This was an understatement of Seira's powers.
As a member of DA-5, Hammer can be assumed to be a skilled fighter with or without his weapons. Hammer is a weapons specialist but can also indulge in combat if needed. He has been shown to use a wide variety of explosives when battling, which became a problem when arriving in South Korea for DA-5, because as Tao stated, the city is peaceful and full of civilians so he could not run free firing explosives as he usually likes to do during missions.
He also used a very heavy type of gun when battling Seira. Other of his equipment include poison gases and sleeping gases. Like other members of DA-5, Hammer can also improve his skills by eating the drug, 'D'.
