Fe-Matoran

A Fe-Matoran was a Matoran with innate Iron powers. The only Fe-Matoran seen were mentioned in the short story "The Kingdom". These included two feeding Avak and Thok, and also the Nynrah Ghosts. In the Bioniclestory serial Brothers In Arms, Mazeka hunts down an unknown Fe-Matoran with a damaged arm in a tavern on Stelt. Mazeka crushes the Fe-Matoran's mask after the Fe-Matoran takes too long to give information about Vultraz.
