The Kanohi Fehja is the of Mask of Telekinetic Motion. It allows the user to pick up or move any object or living thing they want without touching it. Similar to the force from Star Wars.
"Brominax used his Mask of Telekinetic Motion to pick up a large boulder from the fragments of his chair and sling it into Slicer's face."
This mask seems to share the same power as the Kanohi Matatu used by Toa Nuju. However, the Matatu cannot allow the user to lift themself.
