For the beta tester named after this enemy, see Big Fish (beta tester).
Big Fish is an enemy originally appearing in the third Wily stage from Mega Man 2. As it name indicates, it is a robotic fish with a big size. When the player character is close to it, it flies up from pits, then falls down ignoring terrain collision. Despite its low health, only Quick Boomerang and Crash Bomber are capable of harming it. Curiously, Needle Cannon can stick to the enemy, too, and gives feedback as if it harms the enemy, but deals no damage to the Big Fish. Bullets shot with Flash Stopper also appear to impact the Big Fish, but deal no damage to it.
In the Level Builder, the Big Fish is put in the maximum height it is meant to reach. Big Fish's main skin is an 8-bit recreation of its Mega Man: The Wily Wars sprite, while a skin with its original appearance in Mega Man 2 was added in 1.6.2.
- The Big Fish was originally meant to be a developer only enemy and never released to the public, but they decided to in the end. WreckingPrograms secretly added it to the game because the then staff member MrKyurem hated that enemy.
- The Big Fish became a community meme again after 1.6.0's release.
- Big Fish can be carried by objects. It is unknown if it was intended.
- If objects similar to the Falling Platform are placed just right where Big Fish's path ends under it, it can destroy it without any weapon.
