The Harmonizer is a highly advanced piece of technology, mimicking the functions of the large Akrid Nushi by being able to purify Thermal Energy while also giving its host a healing factor, slowing the host's aging process as well. The device was invented by Gale and Mira using the work of the latter's father. Those who have Harmonizers seem to be also dependent on Thermal Energy like air, water or food. Later on in Lost Planet 2, it's seen that mass-produced forms of the Harmonizer have become available to the much of the population of E.D.N. III.
