Dorakyū

Dorachū (ドラチュー ) are aerodynamic, vampire bat-resembling enemies from the Game Boy remake of Donkey Kong. They make their debut in stage 4-5 of the Jungle. They fly horizontally and across the screen, usually passing by ropes Mario can climb. When one of these enemies intercepts Mario, it hangs onto and appears to strangle him. In the colored Super Game Boy version, Mario is shown to turn his face white whilst he chokes. After Mario undergoes the enemy's attack, he drops off the rope he is currently climbing. Depending on the height reached from the ground beneath, Mario might either survive the fall or lose a life upon crashing into the soil.

The name "Dorachū" is a combination of 「ドラキュラ」, Dorakyura (meaning Dracula), and "chu", a mousey squeaking noise. In Mario vs. Donkey Kong, Dorachū are replaced by similar enemies called Kōmori, which borrow the same vampire bat-styled attack pattern.
