When the rings' energy source were discovered, he led a invasion to Earth to retrieve the rings and start extiniction in Earth. Mandarin, who was forcing the world captured him and retrieved the rings by himself and told the history of the Makluans, almost same as the Makluan guardian's story. He then captured the armor heros and cause a battle with their strong Makluans then the most strong Makluan in the Makluan race. After the battle, he let them out of the battle back to Earth, capturing Gene as his prisoner and looking at the occuring events on Earth. When Team B of Earth made it to the overlord's chamber, Tony with the help of Extremis took down the overlord with Howard's device that could disable temporary the rings' powers. The rings were taken by Gene and was taken down, then Iron Man left behind battled. He died after the reactor exploded by Team A.
He used the Makluan Rings for the rings was for him and he could use it to take down worlds, control the Makluan race, also being the powerful Makluan cause of the rings but without the rings, he is weak.
