Toxic Seahorse is one of the eight Maverick bosses from Mega Man X 3. Created by Dr. Doppler out of a liquid metal alloy, he is capable of melting into the ground and reforming elsewhere, making it easy for him to ambush enemies. During X3, Toxic Seahorse was commanded by Dr. Doppler to attack a dam in order to contaminate the water supply for the human population, but this scheme was foiled by the Maverick Hunters and Seahorse was destroyed by X.


  • Acid Burst - Toxic Seahorse's primary weapon is a glob of acidic gel that can bounce off of surfaces and corrode the chassis' of enemies. X can copy this weapon.
  • Liquid Assimilation - Seahorse melts into a liquid form and bonds with his immediate surroundings, reforming himself behind his opponent.


  • Frost Shield - Being made of fluidic alloys, Toxic Seahorse is severely hampered by low temperatures.
