Enguarde

Enguarde the Swordfish is an Animal Buddy in the Donkey Kong series who first appeared 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).

Donkey Kong Country
In Donkey Kong Country, Enguarde is the greatest swimmer of all the Kongs and Animal Buddies 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 use the Supercharge Attack. 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 Buddies 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. Unfortunately, he is incapable of using his Supercharge 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)

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

Donkey Kong 64
Enguarde appears in only one level in Donkey Kong 64, and can only be accessed by Lanky Kong.

Levels:
 * Gloomy Galleon

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

Donkey Kong Country
Enguarde appeared as Donkey and Diddy's Animal Buddy 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.

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 Buddies. 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.
