Corrupted Officer Arnold-K is a crooked traffic cyborg cop. He was one of the Don's best friends, before Dolnero found Gien and Lila. He used his authority as a police officer to mug people. Found by accident, Don Dolnero revives his old friend, who intended to replace Gien and Lila and restart the Dolnero Family. However, though it pained him, Dolnero gave Arnold an upgrade for his weapon, though it was actually a bomb. As Arnold-K is brought in by TimeRobo, Dolnero explains that he ultimately chose his current family, but allowed Arnold to be frozen again to save him from being killed by Gien and Lila.
