Rough, pragmatic, and violent, yet methodical in his approach, Kenny possesses unwavering composure. He believes in a Darwinian order where the strong survive by dominating the weak. His encounter with Uli Reiss, however, shakes this conviction, and he emerges from the experience deeply shaken. For the first time, the balance of power is against him. But through his interactions with the king, a genuine fascination and friendship develop. He will then relentlessly pursue the power of the Founding Titan after Reiss's death, seeking to see if he too could share this utopian vision of the world, and will go to any lengths to see his dream fulfilled. He is also capable of demonstrating a certain humanity, notably when he refuses to let Levi die and gives him the tools to survive in the slums. He also seems to possess a quick wit, coupled with a somewhat theatrical manner in his interactions. According to his disciple, Kenny also had the unfortunate tendency "to forget to mention important things," such as revealing to Levi that they were both Ackermans.Kenny was a tall, rather thin man with a small black beard, hazel eyes, and medium-length brown hair combed back, wearing a black suit and hat.
