I always kind of found it odd that out of all the cool shows that Filmation produced in the 1970s, my least favourite ones got all the merchandising. Sure, I watched Isis on TV but there was no way in heck I could buy a girl doll.
Also, despite being a lover of SF at an early age, I could never get into Space Academy the way I did Ark 2 or Shazam!. Mego actually snapped up the rights to Ark 2 but didn't release any of the planned figures but Aviva, a subsidary of Hasbro released the Space Academy line using the Hasbro Super Joe bodies in 1978. From what I'm told, these were an exclusive for Woolworths.
A year later Space Academy would morph into "Jason of Star Command", a more action orientated series that would, of course, see absolutely no merchandise, boo!
