1. Timeking 2. Ultimate Vilgax 3.Kate Underlocke 4.King Netropolix 5. Zane

Zane is my own, he's an extremely powerful Osmosian who could wipe the floor with Ultimate Agreggor in mere seconds. He appears as the main villain of season 2 of Ben 10: Ultimatrix Forever and the season 1 finale. He has a dark version of the Ultimatrix which he uses to absorb aliens from. It wasn't built to be used, just absorbed.
