Kargon

A shamanish-type guy who somehow became friends with Gamechamp and the Robot Team. He is benevolent but has an evil twin named Zargon. He primarily appears in Member OG 3: Subtitle Soon! when he summons the Light Sword for the OGers at Gamechamp's request and then subjects them to a series tests to prove themselves worthy of wielding it, but he accidentally summons the sword before sending them on the tests which cuts down the time they need to use the sword. At several points he is shown to actually be evil but that is actually shown to be Zargon.

Kargon goes into hiding from Dark Jim eventually, but he also plays a role in the end of the OG due to holding Sophnito and sending it to the OGers in Nero's possession.

He is later mentioned in Member OG 8: This Title is Irrelevant, where it is said that he returned to life without a soul when Earth was restored from its destruction earlier in the series. Since this made him vulnerable to being possessed by the Velvet Monkey, Cerulea found him in time and retrieved the Sophnito from him, instead entrusting it to animal policemen. He is presumably dead by the time of Happy Ending?, but succeeded by his apprentice Dargon.
