Kaiser is part of an experimental military weapons program. The Ruby Galaxy EthRanger suit has been bonded with a living alien metal. This alien metal can transform back and forth from a solid state to a liquid state at will. It can also regenerate any damaged areas and enhance the suit's abilities. This living metal is intelligent and in absolute full control of the suit.

Kaiser comes equipped with dual EthTech energy beam swords and specializes in short range melee combat. Kaiser's speed, stealth, and strength have been pushed to new levels.

Kaiser is the first Demon Subtype, a unique variant of the Galaxy EthRanger suits.
