Suspiciously Similar Substitute: To Tobei Tachibana, even though Tachibana himself was never in Skyrider. Especially obvious in some later episodes, when the Riders from previous series interact with him in a similar way to how they interacted with Tobei, in spite of not knowing him nearly as well.

Degraded Boss: After his death, General Monster's kaijin form, Yamorijin, appears on two occasions later as Mooks alongside other minor second generation kaijin and were easily destroyed by the previous Riders.
Expy: To Colonel Zol from the original series, as both of them are the first commanders of their respective organization and both are former Nazi members.
One-Winged Angel: General Monster not only looks monstrous in his human form, he has a hidden form too. That gecko design on his eyepatch, there from the beginning, is there for a reason.
Portrayed by: Yosuke Naka
Nice Job Fixing It, Villain!: General Monster is activating the explosives planted within his body and charging towards our hero in a last-ditch effort to take Hiroshi with him. Then he gets blasted before he can make good on this by Admiral Majin, who had decided General Monster had failed once too often and it wasn't worth letting him live even until the end of one fight. If the Admiral had waited ten seconds longer, the world might be run by Shocker to this day.
