Denji

Appearance: Denji is a teenage boy with scruffy blond hair, brown eyes and dark circles under his eyes, making him look tired, additionally, his teeth are noticeably sharp and angular; due to malnutrition in his childhood, he is very thin and even has protruding ribs. Before fusing his heart with Pochita's, Denji was missing his right eye which was covered by an eyepatch and several other non-essential organs, including a testicle and a kidney. During this time, he also wore a loose white sleeveless undershirt, a green jacket, and black pants during this time.

Hybrid Form: If the chainsaw's cord is pulled while Denji has enough blood for the transformation, his head will transform into a demonic mechanical form with long, jagged fangs and a chainsaw handle on the back of his head, large chainsaws will emerge from his forehead, arms, and legs, if he so desires. But if Denji's chainsaw cord is pulled while he doesn't have enough blood, then a chainsaw blade will partially emerge from his head. When Denji leaves this form and returns to his human form, the changes that occurred become a liquid layer and melt.
