Tamega

Tamega (タメガ Tamega) was an evil parasite from space of unknown origin that could take control of one or more bodies at once, and is the main antagonist of Silver Gaiden: The World's Might.

Arriving in space after escaping from the Future Corps, Tamega took control of the entire population of the whole world, using Xander as the host. Planning to make Earth match his home planet, Tamega engaged Silver and Gustavo until his core was destroyed.
