For unknown reasons, the spirits of many slain Decepticon warriors fused together into the entity known as Violen Jiger on the Tenth Planet. He proceeded to cover the world in dark clouds, blotting out all starlight and turning it into a barren, desolate world. From then on, he would use it as his base of operations.

After seizing the Zodiac|Zodiac from the Autobots, Violen Jiger returned to his birthplace. The Powered Masters pursued him and managed to defeat his three insectoid forms, allowing them to reclaim the Zodiac, but Violen Jiger was not yet defeated, and revealed his true form as a flaming, phoenix-like mass of Decepticon spirits. The Powered Masters placed their hands upon the Zodiac and channeled its energy into themselves, then united into their combined form of Big Powered to destroy Violen Jiger with the Zodiac-powered "Rainbow Powered Attack". With Violen Jiger eliminated, the rainbow of Zodiac energy transformed the Tenth Planet into a paradise for human and Transformer alike.
