|Mega Evolves from||Gengar (Gengarite)|
When Gengar Mega Evolves into Mega Gengar, a portion of its body sinks into the ground. The lower portions turn a more reddish purple, and a third eye appears on its forehead. This new unblinking eye is oval and yellow. The spikes on Mega Gengar's back are more numerous and pointed. Additionally, spikes appear on its hands and tail. Its ears are now considerably longer and project backward.
Mega Gengar's upper, yellow eye allows it to see into other dimensions.
