Fish (also known as Mecha Fish), are enemies in Epic Battle Fantasy 4. They are mostly found in the Waste Disposal Plant, but some can also be found in the Temple of Godcat. They are clockwork robots resembling fish that hover in the air with a pair of rocket thrusters.
Being mechanical foes, Fish are weak to Bomb. In addition, they share a weakness to Wind, and an immunity to Poison and Earth. They have a variety of advanced weapons at their disposal, but they all possess a dashing attack which buffs their evasion and hits one player for moderate physical damage.
When defeated, all Fish will automatically cast Mini-Missiles (in their case, due to losing their thrusters when they explode), which deals Bomb damage to one of the party members and may inflict Stagger. This attack will not hit if the Fish is destroyed just as the wave ends.
Copper Fish are found mostly in Waste Disposal Plant and few located in Temple of Godcat. In addition to standard Fish abilities, Copper Fish may cast Spark to damage one of your party members with Thunder damage. It can also use its thrusters to deal fire damage. Unlike the other two Fish, it can absorb Thunder damage.
Steel Fish are found mostly in Waste Disposal Plant and few located in Temple of Godcat. In addition to standard Fish abilities, it can blow wind from its frontal vent to deal Wind damage to one member of your party, launch plasma missiles which can stun the party, or shoot a machine gun.
Gold Fish are found in Temple of Godcat. In addition to standard Fish abilities, it has the Copper Fish's thruster burn attack and the Steel Fish's wind attack.
