Teslatron

He appeared in Spirit Rider and "helped" a scientist create a teleported. However, it was actually a portal that could bring the evil entity's kind to the normal world. But Joe, as Spirit Rider-I stopped him. However, Teslatron absorbed the Electro Eye after finding it and became large. He was then defeated by the Iguanatron and Spirit Rider-I using the Electro Eye's powers.
