Ah yes, and here we go with Active's hugest flight of fancy, the Action GameMaster. Not only is it compatible with NES and Genesis and SNES, but also supports its own 16-bit format on CD-ROM! In color! No wonder they put "portable" in quotes - if this thing was actually developed, which it wasn't, it'd kill batteries in minutes, weigh a ton, and cost about a thousand dollars. But there's still more to come...
Cheetahmen action figures were advertised in the mini comic book which came with Action 52 but were obviously never released. There was no photo in the ad; just a drawn visualization of the figures. It's anybody's guess whether these were ever actually made either.
