Shit made of such poor materials, finding one mint is barely possible anymore, so little that it's likely less than 1%. Hard mode- no GPS toys, we know gold plastic shatters. Randy, Black Zarak, Monstructor, UK Predators, movie protoform Starscream, Torca, they break.
This asshole, made of incredible amounts of translucent purple plastic. Good luck finding one without broken shoulders.
Beast Machines ultra class Jetstorm. The chrome falls off even if left in the box. Beast Machines ultra Nightscream, like Gradion, is made of translucent fragile plastic.
There is an old Marx Toys Johnny West made of a caramel-colored plastic that falls apart from age. Gluing it together just invites bits around the glue to break.
Old 80s GI Joes with thumbs snapped or ankles cracked, but I think most versions of Zap shatter like glass.
MOTU Wind Raider or Snake Mountain's cuffs, so poorly made they broke when they were new.
