This is a 1996 OVA that takes the utilitarian mecha concept seriously: these aren't sleek war machines, they're repurposed cargo loaders that a desperate colony jury-rigged into combat frames out of pure survival necessity. The show builds its entire identity on that constraint, treating improvisation as both narrative and aesthetic. You get two episodes of colonists fighting with equipment they were never supposed to fight with, which means every victory feels earned and every loss costs something real.

It's 2535, and Omni, a colony world, has had enough of Earth's oppressive rule and declares its independence. With no established army or dedicated weapons, the rebellion looks doomed. So the rebels convert the robotic Power Loaders used to unload spaceships into humanoid battle tanks, opening a new era of mechanized warfare. Omni's fate now depends on a small group of young female pilots serving in the special Detachment of Limited Line Service, code-named the Power Dolls. The two-episode OVA mixes science fiction adventure with mecha combat.
