ID Masks can change someone's appearance into a completely different one.
Max Tennyson used an ID Mask to be invisible, which shows that they also can be useful for camouflage.
ID Masks can also be used to copy objects, as seen in "Greetings from Techadon," when Ben thought to use Kevin's ID Mask to copy the Ultimatrix symbol and place it onto Vulkanus' back so that the Techadon Robots would attack him instead of Ben.
The image produced by the ID Masks can be momentarily disrupted by flashes of lightning. They can also break and stop producing an image, exposing the wearer.
