Fish-One (purple)

The Fish-One is an enemy that appears in Sonic and the Black Knight. They are a type of the Knights of the Underworld and a part of the Fish-One variant which are tasked with scouting and monitoring enemies. They specialize in firing toxic energy balls at opponents.

Appearance
The Fish-Ones, as their name implies, resemble large normal fish. They possess indigo-colored skin with lavender underbellies and have wing-like pelvic fins, a pointy dorsal fin and a glowing red orb instead of a tail fin. Their whole body is also covered in glowing purple medieval markings. On their head section, they also wear a metal visor with a single eye behind them.

Powers and Abilities
The Fish-Ones are able to teleport to different locations by emerging from black voids. They are also capable of flight through midair by using their flippers.

As their specialty, the Fish-Ones can shoot special toxic energy bombs from their eye which will poison upon contact.

Attack Patterns
The Fish-Ones have two ways of attacking. They will either fly stationary in the air where they will shoot a row of energy bombs at the player (this does not cause direct damage) or fly directly into the player which do cause damage.

Overview
The purple Fish-Ones are a rare type of the Fish-Ones and can only be encountered in a few Missions, such as "Special Challenge: Destroy 12 columns" in Great Megalith. If the playable character is hit by the Fish-Ones energy bombs, he/she will be poisoned and the player will continuously lose Rings for a short while. Blocking the energy bombs with Guard will negate their effect however. Like most other Knights of the Underworld, the Fish-Ones can be defeated with a single, well-aimed sword slash.
