Toxic Seahorse, known as Acid Seaforce (アシッド・シーフォース Ashiddo Shīfōsu) in Japan, is a seahorse-based Maverick in Mega Man X3. Under Dr. Doppler's orders, he took control of a large dam to restrict the supply of drinking water for humans.

His body is made of liquid metal, allowing him to sink into the ground and change his position. His weapon is Acid Burst, which releases globs of acid. His weakness is Frost Shield; since the Frost Shield's normal fire delays before launching, it can be used as a trap for Toxic Seahorse.
