The Cloaking Crystal allows a person to change their physical appearance. (Seemingly as long as the user likes, unless a Blocking Crystal is used) The Cloaking Crystal was used by Master Cyclonis in "Best Friends Forever" and she disguised herself as a girl called Lark and turned both Radarr plus some of her Cyclonians invisible to the naked eye.
Appearance[]
The Cloaking Crystal is shaped like an egg but longer and with pointy tips, with a dark violet coloration.
