Krusha

Krushas are blue-scaled, Kremlings; they are among the elite of the Kremling Krew. All Krushas wear clothing with a camouflage pattern and also have silver arm bands on each forearm.

Donkey Kong Country
Krushas first appear in the game Donkey Kong Country as uncommon foes, portrayed as large, hulking, dangerous and formidable but amiable Kremlings. Krushas attack Donkey Kong and Diddy Kong by walking into them, and can only be defeated by throwing a barrel at them, or by having Donkey Kong jump on them, being resistant to any other method of attack (simply laughing it off). Although it does not harm them, Donkey Kong's Hand Slap attack still causes them to drop a banana every time they are hit by it, making it possible to acquire a virtually unlimited number of bananas from any single Krusha.

Of note, another type of Krusha, gray in color and wearing blue clothing (darker than the regular Krusha's skin), can be found in the Donkey Kong Country levels "Necky Nutmare" and "Platform Perils". The Gray Krushas can only be defeated by throwing a barrel at them, since they'll laugh off all the other attack methods, including Donkey Kong's jump attacks. Unlike the blue variety, they do not drop bananas when Hand Slapped. Both Blue and Gray Krushas can easily be taken out by Rambi.

Donkey Kong Country novel
An individual Krusha (referred to as "the strongest commander") appears as the final antagonist of the Donkey Kong Country novelization. After the Kongs board the Gangplank Galleon and defeat most of King K. Rool's commanders, Donkey Kong and Diddy Kong attempt to attack Krusha, but the reptile shrug off their assault and punch them both. The Kongs then propel themselves using coiled ropes found at opposites of the ship, knocking Krusha unconscious.

Donkey Kong Country 2: Diddy's Kong Quest
While not pointed out in the manual, Kruncha appears to be Krusha in pirate gear in Donkey Kong Country 2: Diddy's Kong Quest.

The Donkey Kong Country comic
In the German Club Nintendo's comic adaptation of Donkey Kong Country, a Krusha makes a small cameo appearance, on the background of King K. Rool's Gangplank Galleon.

The Donkey Kong animated series
In the Donkey Kong animated series, a dimwitted Krusha named Krusha appears as a recurring villain alongside King K. Rool and General Klump.

Donkey Kong Land
Krushas reappear in Donkey Kong Land, where they are essentially identical in all regards to their appearance in Donkey Kong Country; the Gray Krushas seen in that game are absent due to the Game Boy not supporting color.

Donkey Kong Land III
Krushas did not appear in this game though oddly, Knockas were referred to as Krushas.

Donkey Kong 64
In the Multiplayer Mode of Donkey Kong 64, players can gain the ability to play as a Krusha after photographing fifteen Banana Fairies in any of three files in Adventure Mode; the playable Krusha is a large character Chunky Kong, and possesses his own moveset such as a fast sliding attack and utilizes an Orange grenade launcher in combat. Both attacks deal 1½ times as much damage compared to Chunky, the strongest kong. Oddly enough, Krusha never appears in the game as an enemy, having been replaced by Kasplat.

If playable in the main game with gameshark, Krusha is referred to by name from the NPCs, and has unused animations, some of which are taken from Chunky.

Trivia

 * The beta version of Donkey Kong Country had blue Krushas being resistant to Donkey Kong's jump attacks. In the final game, this trait was given to the gray Krushas instead.
 * Future enemies similar to this one include Kruncha, Krumple, and Kasplat.
 * Kasplat is mistakenly called Krusha in the Prima guide to Donkey Kong 64.
