S1·E38 Beetle Mania (1)

Dr. Meta-Evil uses Metabee's medal to control every Medabot in the world! Brass starts to attack Erika and Karin and Kantaroth starts attacking Rintaro and his group. Then, amasingly, we find out that Dr. Meta Evil was once Dr. Hushi's assistant. Dr. Hushi found out the power of the rare medals and he wanted to distroy all his reaserch and findings but Dr. Meta-Evil stole the information to use it for evil. More suprises are in store when it's revealed that Dr. Meta Evil is part machine himself! Peppercat and Sumiliodn attack him but don't do much damage. Rokusho distracts the Evil Doctor as Ikki stes Metabee free. When he does that, the curse is broken.
