Shelfwarmer 

A toy at a store that kids don't want (usually the toy of a sidekick, disliked character or female character, etc) that remains on shelves for months on end after all of the "cool" figures have been sold. Based off of the term benchwarmer

Toy Collector A: Hey, have you seen ROTF Sideswipe lately?
Toy Collector B: Ugh, no, our Target's packed with nothing but shelfwarmers like Arcee and Wheelie.
