Grotch Porto
Accidently discovered fresh yōkan from one particular store, named "Imo-Youkan" make their monsters grow, while stale ones only make them grow for a short time before shrinking them back down to size or reverse the growth caused by fresh ones Invented torpedoes that make monsters grow and only grow
Briefly turned against Gynamo to help RitchiRitchihiker

Stayed loyal to Divatox, but also showed a degree of loyalty to General Havoc.

Temporarily became a giant after first eating imo-youkan Grows giant after going AWOL from  Divatox's crew to prove himself.
Turned good by the finale. Didn't die until presumably the finale to Power Rangers in Space
