Ermac

Ermac was created by Shao Khan from many souls to form one entity. He served under Shao Khan's command and even participated in the invasion of Earthrealm. After Shao Khan's defeat Ermac was still under his control, but he didn't have any orders to execute. This led Ermac to walk the wastelands aimlessly.

During this time he was found by Kenshi. Kenshi managed to release Ermac from Khan's control and make him a free being. As gratitude Ermac thought Kenshi how to use telekinesis.
