Barem Bridge

"We'll be seeing you, Chainsaw Man! Enjoy your normal life while you can!"

Barem (バルエム, Baruemu) is a human-devil hybrid that merged with the Flamethrower Devil and serves as a minor antagonist in the Control Devil arc, where he faces the Chainsaw Devil.

He returns in the current arc of the Academy Saga as a supporting character.

Human Form
Barem's human form is that of a tall man with relatively long black hair that’s swept behind his ears, with the exception of one strand of hair that drops from his forehead and connects to his right eyebrow. During his time as one of Makima's brainwashed servants, he wore a standard Devil Hunter uniform consisting of a suit and tie. After joining the Chainsaw Man Church he ties his hair into a ponytail and he now wears a white buttoned shirt with white pants and black suspenders. He kept his black necktie, now tucked in the shirt's breast pocket.

Hybrid Form
When transformed, Barem has his head transformed into three huge fuel tanks while his neck becomes a jumble of metal parts. His arms transform into giant flamethrowers that serve to attack his enemies.

Personality
Initially Barem's real personality was unknown, as he was brainwashed and mind-controlled by Makima. He was shown to be observant enough to notice Pochita's weakened state, and displayed a rather manic side when blowing up an entire building using his flamethrowers.

When he makes a return in Part 2 of Chainsaw Man, Barem shows his true personality to be rather cruel and callous, casually suggesting murdering Asa Mitaka for the sake of getting to see Denji as Chainsaw Man and then implicitly threatening Denji as he walked away in disgust. He also appears to have a slightly juvenile yet twisted sense of humour, doing things as teasing Denji about his crush on Asa before making his threat, as well as by sticking his fingers in Denji’s nose as a greeting. Despite his rudeness towards Denji, he does appear to geniuenly admire or worship Chainsaw Man, seeing how far he's willing to go in order to see him transform.

Control Devil arc
At an unknown point in time, Barem was brainwashed by Makima to serve her needs. He is summoned as part of Makima's newly-formed Special Division 5, a team of weapon hybrids created for the sole purpose of battling the fully-powered Chainsaw Devil. While under Makima's control, he comments about how everyone in the group adores Makima.

Once Makima commands Special Division 5 to attack, each member activates their weapon trigger, transforming into their Hybrid forms. They all leap from their respective spots to lunge straight towards Chainsaw Man. Before any of the Hybrids can land a single blow on him, they are all blown back by Chainsaw Man leaping forward from the building he stood on to initiate the fight.

After Chainsaw Man beheads Katana Man, Barem appears on the bottom floor and aims his two flamethrowers at the ceiling. Screaming in excitement, he unleashes a large torrent of flames, creating a large explosion that forces Chainsaw Man to escape the building. He is eventually torn to shreds alongside the remaining Special Division 5 members after Chainsaw Man withstands their combined attack of sending him into space.

At some point in the future, Special Division 5's Hybrids are revived once more by Makima, who brings them all to a graveyard to confront Denji. Once Makima finishes monologuing her thoughts of erasing anything she dislikes to Pochita (who is disguised as Denji), Barem and the other Weapon Humans transform into their Hybrid forms for the final battle.

During this confrontation, he attempts to burn down Pochita once the latter is piled up by a group of zombies from the Zombie Devil. Unfortunately, Pochita uses his chain whips to latch onto two grave markers, and launches himself straight towards Makima's group using his chainsaws to slice Barem in half.
