A reoccurring villain inspired by many examples of extraterrestrial invaders in Tokusatsu with Kaiju bodyguards, Keilrix is a representative agent of an expansive extraterrestrial intergalactic union outside the Intergalactic Civilizations Federation, designated with the task of killing Zenithman Tachyon. He has the ability to grow to the size of a Kaiju and, via advanced cybernetic enhancements, can react to high-speed attacks from Zenithman Tachyon.
