Banban

Banban
Mural is a tall, red humanoid figure with two party hats perched on two horns on its head. It has two round black eyes and a toothless mouth with a long, limp pinkish tongue.
Monster
Banban appears as a tall, humanoid Case with red skin. A pair of dark red horns protrude from his head, concealed by festive balloons. The balloons are striped pink, yellow, blue, and white, with ribbons of the same color attached to the top. His body and head are roughly rectangular, and he has almost no neck. Banban's forearms are noticeably larger than his upper arms, and he has three thumbless fingers on each hand. He appears to have no teeth, and his pink tongue is always hanging out of one side of his mouth. He appears to be perpetually smiling. Like other Cases, he is covered in large veins.
Hellish
Hell Banban appears much more menacing and bestial than in his normal form. He is noticeably taller and more muscular. His eyes are completely white and more triangular in shape, with a darker red rim around them. In this form, he is hatless, and a pair of sharp horns are visible. These horns are dark red with black stripes. His mouth is much wider than before, also outlined in dark red, and sharp teeth are visible within. His tongue still protrudes, but it has become longer and has turned a deep crimson instead of pink. The inside of his mouth is jet black, and his hands are slightly larger than before.

Hellish Banban
Hell is a pancreas-feeding monster. In this form, it is known to smell pancreas a mile away. This form is cruel, insane, and savage, despite being able to speak human language. Syringeon created the hellish form of Banban.

Banban is one of the most intelligent cases in the series. Despite this, he believes himself to be Utman Adam, the donor of his genome. This is due to Utman Adam's memories being transferred into Banban's consciousness via DNA. Banban himself is usually very calm and seems to be a good planner (as demonstrated during his encounter with Hellbeak). He also seems unsure of his identity, preferring to be called by the name of his genome donor. Banban is incredibly intelligent and appears to have a good understanding of medicine. He is prone to using his intellect to manipulate others, as he did with Parent by pretending to be someone else and then knocking him out. Despite this, he is polite and seems to feel guilty for the harm he has caused. He even tries to make amends by helping Parent in the Feeding Sector. Banban speaks in a monotone and is largely emotionless.
