Elgitron

Elgitron appeared in 1989 TV series called Kamen Rider Black RX. Elgitron is a black and white robot with the ability to harness electricity. He had two long bowed horns on his head and a sword, all of which served as lightning rods. He and Gatezone pursued a woman named Youko who had a metal that is a part of a puzzle that would release something deadly and ran afoul of Kohtaro. When Gatezone and Elgitron caught up with them, Kohtaro henshined into Kamen Rider Black RX and fought them with Gatezone getting the metals. When Youko charged Gatezone and the spire, it ended up badly damaged by Kohtaro who turned Elgitron's weapon towards it. With Youko falling off the cliff from the recoil, RX became Robo Rider and broke Elgitron's left horn. Robo Rider reverted to RX and destroyed Elgitron with his Revolcane.

Elgitron was later revived by Maribaron as part of the Spirit World Inhumanoid Army.
