Oblivia (Opposition Butchering Levithian In Violent Indescribable Anger) is an violent killing machine, it uses very high-tech blades and other things to shred through towers or anything that dis-obeys her. She's a powerful boss that's more than capable of flattening opponents, She just stays on screen flattening your towers so other things can get to the exit. Although she has 5,000 more health than in-game but she teleports out before you can finish her off.
