Anyone know more about these figures?
 

I think this is a Voltron, Animated Robin, 60s Batman, Dinorider?, TMNT villain, some sort of Italian figurine (it has "Italy" marked on the bottom of it), Cable, and Harry Potter? Anyone know more about these figures that might help?

Bottom left is vintage tmnt Mutagen man

Top left is 200x Masters of the Universe "Man at Arms"

Man-at-arms, batman, animated robin, cable, mutagen man, a dino rider, a zoid, and harry potter.

Man-At-Arms (He-Man) | Wee-Quay (Kenner Star Wars) | Batman (Looks like a gift shop PVC) | ??? | Robin (The New Batman Adventures) | Cable (Marvel X-Force)

Mutagen Man (vintage Playmates TMNT) | ??? | ??? | Harry Potter

You asked if we know more about them - I can tell you with no negative intent or attitude that they are all fairly unremarkable, all lack accessories (from your picture), and none are "market movers". Again, no negative intent with that commentary but rather just some market info. :)

Thanks for the details. I'm not really concerned with their value, I just wanted to know more about them.
