Bionicle "Minifig" parts

[Orion Pobursky]

To me, it's really as simple as: because they are Bionicle figure parts, and they are not minifig parts.

(If the above statement isn't true, then of course they could go under minifig. Do these parts work together with minifig parts? Can one build a minifig with them?)

Can you "build a minifig" with the Star Wars battle droids?
Also, in the case of the weapons, they are usable by minifigs and fit minifig hands.

Anyway, they'll stay in Minifig. If we want to recategorize, let's do that but somebody needs to do the legwork for the rest of the non-minifig figure parts.
