Ultimate Annihilator

The Ultimate Annihilator was a devastating weapon created by Dr. Ivo Robotnik and 3235 capable of erasing matter. Robotnik had intended on using the device to erase Knothole from existance and thereby defeat the Knothole Freedom Fighters once and for all. The weapons was powered by a nuclear power core. Although he managed to fire the weapon, Robotnik's nephew Snively had altered its programming to specifically target Robotnik's DNA. Thus, only Robotnik was erased from existence. However, the weapon being fired had after effects, weakening the dimensional barriers with other zones and returning Echidnaopolis to Mobius Prime as well as allowing the Dark Legion to escape the Twilight Zone.
