[Dr Kain]

So NDK's panel submissions go live on Sunday and aside from my Sentai vs Kamen Rider Game Show panel, I want to do one titled "The Darkside of the Spandex." My plan is to show clips featuring evil rangers and riders (Shadow Moon and Ouja are a must), but I'm trying to decide on who I should show for evil ranger villains. I know I'm definitely going to do the Neiji Rangers from Mega and the Hana Rangers from Kaku, but who else should I do?
