Orca is a killer whale-mix who works for KNIFE.
Standing at 6' 2", Orca is an androgynous-looking person with an appearance which reflects his killer whale mix. His hair is two-toned; black on top and white underneath with the two white circles seen on killer whales.
He is usually shown wearing a white shirt, a black apron, and black pants like his hair colors. Typically always has his hair tied up, only several times leaving it down, occasionally being pulled down after a fight.
He is rather calm, composed, and logical compared to Baekmorae and Medusa. He comes across as stoic and rarely shows any emotions besides worry or surprise. Mostly coming across as a very unhappy individual, this could be the result of not agreeing with the way the rest of KNIFE handles things.
Orca is highly respectful, of Baekmorae and Medusa both, and will follow commands without question. He is strongly affectionate towards Medusa and has put himself in harm's way multiple times in order to keep her safe.
Guineung seems to be one of the only few individuals who make him outwardly angry.
It has expressed several times how much he dislikes KNIFE's disregard for human life, going as far as to say Baekmorae treats it like a game. Even becoming upset when finding out that individuals were killed unnecessarily.
When he was a child, although it wasn't stated directly, he was a test subject at the immortality lab. When Baekmorae killed everyone at the lab, he decided to spare a young Orca who was being protected by Medusa. Baekmorae stating that he would need someone to help with his agenda. Medusa, in turn, defended Orca by saying '...If you let us live, I'll do anything...' adding that due to the experiments his arms were completely numb and he wouldn't be able to help. In turn, Baekmorae cured them.
Orca has since been a team member for KNIFE, usually following close by Medusa. He's often the most called on out of the group possibly because he's much more willing then Medusa to follow orders. Including following up with Naga after their initial confrontation.
It's later revealed that he has no desire to harm anyone unless he finds it absolutely necessary, even as far as ignoring Hyena's direct attack against him.
- Super Strength: Such as Killer Whales, Orca has commendable power and is strong enough that, in SPOON, Dana is the only member on par with him. In some fights, he uses a whip.
- Enhanced Sense of Smell: He is able to track peoples scent like when he tracked Naga, Hyena, and Amore in Chapter 76.
- Enhanced Physical Abilities: Other than smell, it appears that Orca has enhanced speed and hearing due to being a Hybrid.
While it can be interpreted as respect even as an adult Orca is incredibly afraid of Baekmorae, however because of this fear he will never go against him or make him upset. Orca is most afraid of him when he isn't smiling because to him he looks like "a monster imitating a person".
Orca greatly loves Medusa and will do anything for her, to the point he fretted when she said the ends of her hair had gotten a bit dry. Because of his crush, he sometimes gets jealous of other guys or anyone Medusa finds attractive in general.
They are not shown to interact much.
Orca distrusts him to a certain extent and doesn't care for them. He isn't particularly bothered when he dies.
Orca doesn't seem to distrust Lady but he also doesn't seem to care for her.
Orca considers him an annoying pest but likes to believe he is more mature than him. Still, whenever they see each other they get into a fight.

- Guineung dislikes Orca due to a childhood fight between them in which Guineung did not win.
