Kopter

Kopters are small yellow-ish Kremlings (resembling another Kremling, Bazuka) that are encountered in a few of the later levels Donkey Kong Country 3: Dixie Kong's Double Trouble! and Donkey Kong Land III. Kopters carry helicopter blades in each hand and can attain flight by spinning them rapidly, if either Dixie or Kiddy Kong get to close they could end up be being hit by the blades. Kopters also wear crash helmets meaning jump attacks are useless, but if the Kongs can land directly on the helmet they will bounce thus attaining greater heights. Kopters were very uncommon enemies in the game since they only appeared in the levels Buzzer Barrage, Kong-Fused Cliffs, and Pot Hole Panic.

In Donkey Kong Country 3, Kopters cannot be beaten in any way and can only be avoided. However, in Donkey Kong Land III, they can be defeated by simply jumping on their heads; they also manage to defeat themselves by landing on the ground but respawn when the Kongs aren't on the same screen as them. A Kopter (wearing slightly different armor) appears in Donkey Kong Barrel Blast as a rival of Wrinkly Kong. In this game, he looks more like a Kremling, having greener skin and a tail.

Trivia

 * According to the game's credits, Kopters belong to the "Kremling Kreeps" enemy class.
 * Through hacking, it can be seen that Kopters used to have standing and falling sprites in Donkey Kong Country 3.
