Enguarde

Enguarde the Swordfish is an Animal Friend in the Donkey Kong series who first appears in Donkey Kong Country; he shares the most number of appearances in the series with Squawks the Parrot (though Squawks only carries a flashlight and is not playable in the original Donkey Kong Country). The options for his name are "Enguarde," "Swordy," and "Stabber."

Donkey Kong Country
In Donkey Kong Country, Enguarde is the greatest swimmer of all the Kongs and Animal Friends and is invaluable since they are generally helpless underwater and his pointed bill can be used to attack enemies there; however, he is useless on land and cannot jump out of the water.

Levels:
 * Coral Capers
 * Clam City
 * Croctopus Chase
 * Poison Pond

Donkey Kong Country 2: Diddy's Kong Quest/Donkey Kong Land 2
In Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, Enguarde can rev up a Superstab maneuver. When released, he can use his bill to break through walls or defeat a line of enemies.

Levels: Enguarde appears in both versions unless otherwise stated.
 * Lockjaw's Locker
 * Lava Lagoon
 * Glimmer's Galleon (Donkey Kong Land 2)
 * Arctic Abyss
 * Clapper's Cavern (Donkey Kong Country 2: Diddy's Kong Quest)
 * Animal Antics (Donkey Kong Country 2: Diddy's Kong Quest)

Donkey Kong Country 3: Dixie Kong's Double Trouble!
Enguarde is one of only three Animal Friends who get to fight a boss character. Enguarde fights Barbos the sea urchin during the events of Donkey Kong Country 3: Dixie Kong's Double Trouble! and Donkey Kong Land III. He is incapable of using his Superstab attack in Donkey Kong Land III.

Levels:
 * Tidal Trouble
 * Bazza's Blockade
 * Floodlit Fish
 * Pot Hole Panic
 * Poisonous Pipeline
 * Barbos's Barrier
 * Dingy Drain-Pipe (Game Boy Advance Remake)
 * Stormy Seas (Game Boy Advance Remake)

Levels:
 * Seabed Shanty
 * Ford Knocks
 * Koco Channel
 * Barbos Bastion
 * Coral Quarrel
 * Deep Reef Grief

Donkey Kong 64
Enguarde appears only in Gloomy Galleon in Donkey Kong 64, and can only be accessed by Lanky Kong.

Donkey Kong Barrel Blast
Enguarde appears in Donkey Kong Barrel Blast as a ridable Animal Friend in underwater levels once he is released from his crate.

Donkey Kong Country
Enguarde appeared as Donkey and Diddy's Animal Friend in the third part of Club Nintendo's comic "Donkey Kong Country". Donkey Kong and Diddy Kong ride him through a body of water, while being attacked by several underwater enemies. An exploding TNT Barrel pushes them out of the water and onto King K. Rool's ship Gangplank Galleon, after which Enguarde does not appear again.

Super Mario-Kun
Enguarde appears in issue 14 of Super Mario-Kun. After Donkey Kong and Diddy Kong ride on a fake Enguarde, Mario and Yoshi find a box that contains Enguarde. They meet Donkey Kong and Diddy Kong in ropes. Before Mario can do anything, he gets attacked by a Croctopus. Enguarde saves him, but a Clambo breaks his nose. Mario responds by attaching a drill to his nose. Enguarde then plows through the Croctopus, breaking its arms.

Trivia

 * Enguarde gets his name from the French phrase used in swordfencing: "En garde"("on guard", "put your guard up", ie: "be ready"), due presumably to his long, pointed, sword-like nose.
 * While Enguarde is presumably one character, two can be seen on-screen in the Donkey Kong Country level "Coral Capers".
 * Early screenshots of the canceled game, Donkey Kong Racing, showed that Enguarde was going to be one of the many ridable Animal Friends. These screenshots also showed that other, differently colored swordfish were going to be rideable; whether these swordfish were simply color swapped Enguardes or entirely new characters is unknown.
