Orca is a character in Children of the Whales. He is the Commander of the Falaina Extermination Forces and Lykos' older brother.
He has long white hair, red eyes, and tan skin. A distinctive scar cuts diagonally across his face. He wears a long black coat with red trimmings with a purple-red sash as a belt.
At some point during the last seven years, he acquired the scar on his face, as it was not visible when he appeared in Lykos' memories seven years ago.
He acts as the commander of the Falaina Extermination Forces sent to exterminate the inhabitants of the Mud Whale. Supposedly, he came up with the plot to ambush the Skylos Infiltration Force.
After the destruction of the Nous Skylos, Orca is tried and sentenced to death. However, Orca manages to escape his sentence by telling the council of the daimonas that was responsible for the destruction of the Nous, and how they must capture the daimonas in preparation for the second apocalypse. Orca lays the blame for the failure of the mission entirely on Arachni's shoulders, and Arachni ends up drawing a weapon and shoots off the ends of two of Orca's fingers when he believes Orca is going to draw a weapon on him. With that, Orca convinces the council that Arachni was at fault for having such poor control over his emotions.
Orca is Lykos' older brother. However, he does not seem to care about her very much. He seems willing to use her as a "research sample" on how the Falaina affects people.
