Irokus was created millions of years ago along with the other original Eight Guardians of Terra. Years after Terra was created, the Tree of Life came into existence and created Irokus and the other guardian Kaiju. Like his siblings, he was given an element to keep balance and order on Terra, in Irokus's case he was given the element of fire. During the Late Cretaceous Period, King Ghidorah and DesGhidorah invaded Terra in a joint attack, which caused the extinction of the dinosaurs. Irokus and the other guardians battled the two space Kaiju and successfully defeated them, sending King Ghidorah into retreat while DesGhidorah was sealed away beneath Infant Island by Gigamoth.
About 77,000 years ago when the first civilizations had appears around the world, one of the eight guardians when rogue and caused great destruction, resulting in another mass extinction, resulting in 10% of the human race remaining. Irokus and the other guardians fought against their former comrade and sealed in away and sending him into outer space to prevent anymore destruction. In order to save the rest of the human race, Irokus and the remaining guardians sacrificed their souls to the Tree of Life, which managed to restore the human population. Irokus and his fellow guardians where placed in a state of limbo as they watched over the humans on Terra as well as other universe.
