I decided to make a list of what could be the most useless powers ever.
Mask of Slowness: Creates a field of that reduces speed around the user. Unfortunately, it effects the user as well.
Mask of Self-Destruction: Explodes immediately after the first use, killing the user
Mask of Permanence: The mask fuses to user’s face forever preventing them wearing any other kanohi.
Mask of Flames: The mask engulfs the user in flames.
Mask of Bees: My god. THEY’RE EVERYWHERE!
Mask of Laser Face: Upon activation, the mask fires lasers. (Okay, this one is cool.)
Mask of Sonic Repair: Fixes and manipulates things with the power of sonic. Except for wood. It doesn’t like wood.
Mask of Forbidden Knowledge: The user becomes aware that he/she and everything around him/her is a LEGO product and is driven mad by the revelation.
Mask of Blindness: No power. The mask maker just forgot to make eye-holes.
