Kharrus was a member of the Shadow Kin and loyally served his King Corakinus.
When Corakinus' began sharing schoolgirl April MacLean's heart in order to stay alive, after his own was displaced after being shot by Miss Quill's displacement gun, Kharrus was enlisted to find a way to break the connection between Corakinus and April. Kharrus came up with the idea of using an "anchor of a life blood" that would be attached to the heart to force it to stay in Corakinus' body rather than swap between his and April's. This failed and an enraged Corakinus executed Kharrus. (TV: Co-Owner of a Lonely Heart
