The Egg Smasher is Smash series exclusive boss piloted by Dr. Eggman(aka Dr. Robotnik). For those who have played Sonic Unleashed, this boss is very similar to the Egg Dragoon. For those who haven't played the Blue Blur's most recent release, The Egg Dragoon is similar in appearance to an over-sized Egg Fighter robot with hover jets instead of legs. The Dragoon's right hand has been replaced with a Gatling gun(a type of machine gun) and his left hand has been replaced by a lance that also functions as a drill.
