As Mega Sableye, all the energy from its Mega Evolution is concentrated into the red jewel on its chest, causing it to detach from Sableye's body and significantly increase in size; the detached jewel leaves a small hole in Mega Sableye's chest. Its ears elongate, and it gains a spike on the top of its head. Its teeth turn from white to yellow, and its eyes also change from pale blue to a crimson red, with diagonal slits at their inner edges. The enlarged jewel is said to boast such incredible hardness that no attack can even leave a scratch on it. During battle, Mega Sableye shelters itself behind the jewel, from where it can take advantage of any openings its target leaves exposed.
