Black Dragon is a controlled [[mecha|zord-like machine]] from the [[Mighty Morphin Power Rangers]] comic.

The Green Chaos crystal that [[Witch Bandora|Rita Repulsa]] gave Scorpina became charged with green chaos energy it collected from fighting Tommy. When Tommy, Jason, and Zack started arguing at the Command Center, the crystal opened a portal (and blew up half the Center) allowing the Black Dragon to emerge in a gigantic size. He shrunk down and confronted the rangers, offering them a chance to surrender but they refused. He walked right through the rangers, seemingly trying to drain their powers every chance he got. Most of the rangers escaped Black Dragon in the pocket dimension but he managed to grab Billy and knock him out. When Rita and her forces arrived at the wreckage, Black Dragon used Billy's power coin and the Green Chaos crystal to tap directly into the Morphin Grid and absorb Jason, Zack, Trini, and Kimberly's powers.

It later turned out that the Black Dragon was a zord-like machine, reconstructed using parts from the [[Dragonzord]], controlled by [[Lord Drakkon]].
