The Hunt on Le-Metru#
Phase Dragons originated as natural predators of movement itself. They'd chase airships and vehicles down the test tracks, driven by an almost obsessive love of speed. What set them apart from other RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts. hunters wasn't raw power. It was their phasing ability. When traveling at high velocities, any ordinary creature would've crashed constantly into obstacles. Phase Dragons simply ghosted through them, their bodies becoming semi-transparent and insubstantial at will.
The Rahaga noted they posed little threat when the city thrived. Traffic and movement kept them engaged, satisfied their urge to chase. They weren't hostile. They were athletes in an endless stadium, hunters without malice.

Phase Dragons, suddenly without their primary stimulus, grew bored and increasingly dangerous. They'd charge at anything moving, from MatoranMatoranThe most abundant species in the Matoran Universe, chosen by Mata Nui to inhabit and maintain his cosmic body. to other RahiRahiThe Rahi were the biomechanical wildlife of the Matoran Universe, built largely by the Brotherhood of Makuta, ranging from background fauna to engineered war beasts.. But they'd miscalculate constantly, misjudging their strength in pursuit of that old rush. A creature once harmless had become a genuine hazard, not from malice but from pure, aching need for stimulation.

There, they found open skies and room to run again. They're one of Bionicle's better design concepts: a speed junkie with a ghost power, gentle when stimulated and dangerous only through boredom. Born from a 2005 contest design by David Daut, they stand as a reminder that Bionicle's creatures had genuine drives and needs, not just combat functions.
