Chameleon Manta

The Chameleon Manta is a technology used in Metroid Prime. It is utilized by the Omega Pirate and by the Shadow Pirates to render themselves invisible to the naked eye. If Samus Aran is in combat with the latter, she can use her Thermal Visor or X-Ray Visor to track their movements more easily. The Omega Pirate is invisible to everything but the X-Ray Visor, though for a few seconds after its armored plates are destroyed it cannot be seen in any visor.

The USR 3 in Metroid: Other M use a similar ability.
