How's this for a Silver/Bronze Age type villain:
Cyborilla, half ape, half whatever mechanical device he wants to be - in this case, a sort of flying saucer with menacing mechanical arms, etc?
Think he can be both a funny Silver Age villain AND yet still be menacing in the Bronze Age.
And, also "Cyb" + "orilla" I find hilarious!
I'm trying to attach an image, but .... who knows
