E-99 Eggsterminator

E-99 Eggsterminator (a.k.a. Egg Emperor in Japan ) is the robot form of the Egg Fort II, the Eggsterminator was unleashed by Eggman when he was facing both Sonic and G.U.N.'s Beetle robots. Powered by six Chaos Emeralds, Eggsterminator could move faster and attack stronger than Sonic. Unfortunately, all the power sent him out of control, causing him to attack Sonic and co. without hesitation and glow an orange color. However, Eggsterminator was destroyed when Super Sonic, charged up with the energy of all seven Chaos Emeralds, rammed through it multiple times. The Eggsterminator was named "Egg Emperor" in Japan, and the name may have been changed to avoid confusing it with the "Egg Emperor" from Sonic Heroes.
