Farscape
Lost in Space
Babylon 5
Space: 1999
and lastly they have made I-Men out of these but I would just love Thundarr the barbarian complete with the horses they rode
other top notch choices might be
Eternity
the living tribunal
the stranger
(a series of) celestials
the frost giant from Thor (whos name escapes me at the moment)
ya know if they are going to put a bunch of dated cheesy 80's movies into minimate form hows about a little love for Buckaroo Banzai before Madonna of all things
