The Copper Fish is a foe in Epic Battle Fantasy 4. It appears primarily in Waste Disposal Plant and Temple of Godcat. It is a member of the Fish enemy class.


Copper Fish look like copper colored robotic fish with a single "eye" on its top and a small winding key on the back, as well as rocket boosters with orange flames coming out of the engines.


The Copper Fish is possibly the most aggravating foe in the Waste Disposal Plant, if only because it has absorption to Thunder, which most of the foes in the area are weak to. Along with the trademark Mini Missiles of the Fish family, the Copper Fish's presence requires the player to switch tactics.

The Copper Fish can use Thunder and Fire attacks, along with a skill it can use to bolster its own Evade. The Copper Fish also possesses the signature attack of the Fish family: when defeated, the Copper Fish will fire off a pair of bombs to damage and Stagger a single player. Alternatively, if the Fish is killed last, the wave will end.

The Copper Fish absorbs Thunder, is immune to both Poison and Earth, and is weak to Bomb as well as Wind. While the atypical Thunder absorption makes it tricky to fight, the party can readily take it down with Shockwave, Big Blast and Air Strike.
