Beam

Beam (ビーム) is a Shark Fiend (サメの) and a Public Safety Devil Hunter from Special Division 4.

Appearance
In his normal appearance Beam is a young muscular man with a shark's snout and fin emerging from the top of his head. He has short, spiky black hair.

When he transforms into his devil form, his head becomes a massive shark's head with three pairs of eyes. In his full transformation, his entire body resembles a shark but with multiple sets of long fins that he uses as legs.

Personality
Beam is very eccentric. He often goes along with Denji's plans no matter how crazy they are due to having a lot of respect for the Chainsaw Devil.

He is shown to greatly enjoy fighting, eagerly diving into packs of zombies and eating them.

Katana Man arc
Beam is among the fighters from the Special Division 4 that are tasked with invading Akane Sawatari's hideout. He emerges from the wall belowground and dives into the pack of zombies, partially transforming his head into a shark's head and kills several of them with ease. He almost accidentally bites through the Violence Fiend but is punched back by him and reverts to his original self.

Bomb Girl arc
After Power drinks too much blood in the attack on Akane Sawatari's hideout he is assigned to be Denji's partner. He is very happy to be partnered with him and calls him Master Chainsaw continuously. He follows Denji around when he is out by swimming through the floor. This allows him to save Denji when Reze attacks him and tries to take his heart. As soon as he jumps away with him he realizes that Reze is the Bomb Devil. He tries to dodge her attacks to no avail and therefore just attacks her with his shark head attack but she quickly defeats him. Thanks to a distraction he quickly escapes with Denji to an Anti-Devil 2nd Division Training Centre and informs Aki about the Bomb Devil. They try to escape by car but the Bomb Devil catches up to them. After Denji is defeated for a second time Beam reveals how the Chainsaw Devil used to move around in the past. Denji makes Beam transform into his full shark form and mounts him. They attack Reze and the Typhoon Devil and manage to kill the Typhoon Devil. Reze attacks from above but Beam puts Denji in his mouth to protect him. Beam is later on a beach and revs Denji's engine to fix his broken neck.

Abilities
Intangibility: Beam has the ability to swim through solid objects, allowing him to pass through walls and the floor with ease.

Shark Transformation: Beam can transform his head into an enormous shark's head with multiple eyes and great biting power. With his full transformation, Beam's entire body transforms into his Shark Devil form.
