E-10000Y

E-10000Y is an enemy robot seen in the Egg Factory level of Sonic Riders. It can not be played as, and is instead used as an obstacle. E-10000Y is small, yellow, and floats just above the ground as it has no legs. Its main purpose appears to try and capture intruders in Eggman's base, but they appear not to be able to tell the difference between intruders and Doctor Eggman, as they will attack even him when they see him. When playing Egg Factory's frozen version, Ice Factory, the robots are instead used to spray ice around the factory, and are still obstacles.
