These toys came in collections called Adventure Series Playsets. I had several of these as a kid and loved them despite their relative simplicity. The Star Base Zues playset was my favorite because the ships and figures fit right in with my Star Wars figures, Micronauts and diecast Star Wars ships.
If you look closely at the Zues and Flash Gordon sets, you’ll notice some similarities…I actually prefer the wingless versions of the ship.
The Bio-Tronic Man set is a pretty clear nod to the Six Million Dollar Man. Not sure about Capt. Lazer though…
