The X Robot[1] is a robot created by an alternative version of Dr. Eggman.


While Sonic and his friend's were demonstrating their skill's for the Station Square Today, Dr. Eggman spied on them and combined the abilities of Sonic, Tails, Knuckles, and Amy Rose into his newest robot. The robot was able to easily right the group by using their own power's against them, it was only until Sonic decided to work together with his friend's were they able to beat and destroy the robot. (SX: #24)

Eggman collected its remains and kept them floating in a tube. (SX: #40)


The X Robot has the ability to copy the moves and attacks of its opponents, very similar to Emerl's abilities it can change modes on the fly between Sonic, Tails, Knuckles and Amy. With Sonic mode it has Sonic's speed and Spin Dash, Tails mode gives it Tails' flying ability, Knuckles mode Knuckles's strength and spiked knuckles, and can also turn it's hands into Amy's Piko Piko Hammer in Amy mode.

A weakness of the robot however was that when in Amy mode it was in love with Sonic.

Background Information[]

  • The crew for Sonic X could not decide on a name for this robot, and considered both having a competition to name it and to bring it back later, however neither of these occurred. The name "X Robot" is used as it is the title of its concept image on Yardley's DeviantArt, where he also refers to it simply as "Eggman's robot".[1]
