Sometimes I call him "Catty kit" just to keep him on his toes

By the end of the late 36th century, the energy demands of Gigantic Walking Mechanized Battlemechs have far exceeded any conventional means of power generation - even that of the highest capacity.

As such, the only thing that can power these titans of mechanical mayhem is harnessing the near-limitless potential of genie energy. In actuality, it requires more than one genie, because additional genies are required to be on deck for when and if the current power-producing genie gets tired. In fact, for any given Mech, it is recommended to have at least three genies available any time.

This is, of course, why we call it a "Few Djinn Reactor".
