Would like to point out a correction that the big bad guy's name is Tankjou according to the katakana writing on the scan. The name is most likely a portmanteau of tank and jou(the kanji pronunciation or kan-on for castle in Japanese), which makes sense cause he has a castle motif with a big cannon sticking out of his chest.

Creon is most likely a portmanteau of either creature and freon or creation and freon. Freon is the name used by some for what is Chlorofluorocarbon. And since Creon is the one that will be creating the monster of the week, if my assumptions are true, maybe Creon will be using some sort of spore or gas method to turn people into Mynasaurs. Probably explains why he looks like a distorted mushroom with limbs.

And lastly my guess is that the word Mynasaur could be a portmanteau of minion, dyna-, and dinosaur.
