Johns' best story with the Imp was probably "Stealing Thunder" where the Ultra-Humanite put his brain into Johnny Thunder so that he could steal the pen from Jakeem. So I'll call it now -- the season ends with Brainwave defeated, but his consciousness goes into Mike and he uses him to get the pen and take over America. Leading into season 2 where the heroes have to band together to win back America.
Nah, sounds too complicated.
That would make for a good season ender, a;most as in to be be continued, and maybe that Imp amd Mxy will be the reason kara and SG can meet next season?
