Why didn't Mego release more Spidey bad guys?

[Nostalgiabuff]

as a kid I loved having villains for the heroes to fight. I don't understand why the villains are always left behind. Green Goblin was one of those figures I never had as a kid and always wanted and he was one of my holy grails.......now that I have him he is one of my favorite Mego's.
I also always loved Joker and Riddler. they were great scults and costumes and people for Batman and robin to kick the crap out of.

You would think that Captain America - an early MEGO that was a very
popular character - would have at least gotten his major foe made.

Can you imagine the meeting between Marty, Neil, and the designers
looking over the artwork Marvel sent them?

Marty: "Captain America is selling good. Why don't we make a
Super Foe for him? Who's his biggest bad guy?"

Neil: "That would be the Red Skull. Joey - did Marvel send us
some art for him?"

Joey: "Yeah Neil - it's right here. Basic green jumpsuit, black
boots, and a big swastika on the chest."

Marty: "A what? Are you kidding me? There is no way this
company is making a freakin' nazi! Anybody else?"

Joey: "Well, there's Batroc the Leaper. He's french and fights
with his feet."

Marty: "Oh well - I guess Cap will have to fight Dracula and
the Mummy."

I was going to say why not Baron Zemo but I'm sure a figure of a guy with a purple rag on his face would have met with the same results. Of course who knew in the early 80s Hasbro would give G.I. Joe a bad guy with a blue rag on his head. But that's neither here nor there.
