Knives is portrayed as an antisocial, cruel, and commanding character, even to his allies. Knives is able and willing to commit grand and repeated acts of homicide with no signs of remorse, in fact revelling in them. He is shown to be austere and very prideful, holding a strong conviction in his moral authority. Any challenges to his logic are met with violence. He firmly believes in the superiority of the Plants over humans, particularly his own supremacy as their self-appointed leader.
