Sparky was the top half of the Racing Drone that came through the portal with Vert , which Monkey re-programed. Later, Shirako gives Monkey some drone legs that he got in a realm so Sparky could have legs. It consists of Racing Drone parts and garbage from around the Acceledrome . Monkey called it Sparky because sparks would fly from it's joints often. This trait can be annoying, and even dangerous. The robot almost blew up Pork Chop by fueling up his motorcycle. The only thing Sparky usually says is "hello!".
The re-programed drone went with Vert through the Ultimate Race against Gelorum .
