Image Inducers are created on Earth as a miniature gadget for aliens. The inducers allow aliens to hide in plain sight as humans, hiding their distinctive features.
The Necrian Image Inducers greatly differ from that of humans, with their inducers appearing as common accessories such as glasses and rings. Additionally, they are able to completely alter their users' physiology and allow them to physically appear as humans.[1]
Other than aliens, the Image Inducers are used by villainous individuals impersonating others, such as Eve Tessmacher and Tyson Sykes, who impersonated an unnamed Gotham City citizen.[2]
Shape-Shifting: The Necrian variant of the Image Inducer alters their body shape to appear as humans, and the image could also be maintained through the use of magic.
