Metal K-0, as the name suggests, is the roboticized version of the show's main character, K.O. He made his debut appearance in the episode Let's Meet Sonic. What makes Metal K-0 visually striking is his robotic appearance that mirrors K.O. He sports sharp metal hair, complete with a stylish red headband. His two large eyes with red pupils, along with a black visor, give him a distinct look. Metal K-0's face is topped with a metal grey chin adorned with screws, adding to his robotic charm. A fanart OK K.O.! Let's Be Heroes cursor with Metal K-0.
