Egg Walker

The Egg Walker is a large robot and the final Boss Tails faces in Sonic Adventure. It is a large robot with four legs that attacks by dropping bombs, shooting missiles, and trying to stomp Tails. The only way to beat this boss is to first incapacitate the legs, and then hit Eggman directly. The number of legs you have to hit is increased as the Egg Walkers health dwindles.

The Egg Walker has only been used once to date. After Eggman's attempt to destroy Station Square via missile is foiled by Tails, the doctor loses his temper and faces the young fox with the Egg Walker. However, Tails defeats the giant bot, much to the adiration and joy of the residents of Station Square.
