Minifigures & Standout Parts

Standout parts (per reviewers)

Light gray bone pieces
Rarely used color that reviewer notes is "definitely going to be useful for custom stuff"; comes in two variants—some with extra lengthening pin holes and standard upper leg/arm sizes.
Black armor pieces in number 6 size
Relatively long pieces in this color; reviewer notes "compared to most of what we've gotten in the black color in the past"
Yellow armor pieces in number 3 size
Featured armor plating for the character design
Feet from Ben 10 action figure series
Reused from older Ben 10 LEGO line; reviewer acknowledges some elitism about Ben 10 parts but defends their use: "they're just pieces of plastic and here they are on a brand new Hero Factory set"
Long spike pieces in bright silver
Contributes to striking weapon design
Rotating saw blade / razor slider
Has technic pin hole in the middle allowing rotation; described as "razor blade slicer thingy that rotates"
