Hydro

Hydro was a warrior from Earthrealm who was a member of the Lin Kuei clan. He appears in the Mortal Kombat: Blood & Thunder comic books.

Overview
Hydro was a close friend of Sub-Zero and a fellow Lin Kuei. He journeyed with Sub-Zero to combat the forces of Outworld. Hydro has the ability to control water and even blasted strong waves of water that were so freezing cold that they could actually freeze the opponent upon contact.

After Sub-Zero and Hydro fought in Outworld, Hydro was killed by Scorpion in Outworld as part of the undead wraith's promise of killing all of Sub-Zero's friends and family before killing Sub-Zero himself.
