Chaos Shadow

Chaos Shadow is a transformation used by Shadow the Hedgehog. He can assume this form by taking off the Inhibitor Rings from his wrists, thus allowing him to tap fully into the Chaos Force.

Appearance
When turing into Chaos Shadow, Shadow's physical body proportions does not change, but his entire body turns into a reddish-yellow hue due to the massive amounts of energy that is released. Shadow's pupils and irises also vanish upon his transformation.

History
When Enerjak was revived, Shadow confronted him and transformed into Chaos Shadow in an attempt to defeat him with a Chaos Blast, but failed. After continuing to fight Enerjak for while, Shadow was unable to maintain this form and was defeated. (StH #182)

When Sonic, Shadow, and Rouge were trying to stop the Doom Laser from getting into a position to fire at the Freedom Fighters, Shadow thought it was impossible to stop it. He then took off his Inhibitor Rings, gave them to Sonic, and ran in front of the laser. He turned into Chaos Shadow and used Chaos Control to stop the machine. (SU #2)

Powers and Abilities
In this form, Shadow can tap fully into the Chaos Force, which grants him an unlimited supply of Chaos Energy, essentially making him a dynamo of raw power, though at the cost of draining his stamina severely. This increases all of Shadow's physical abilities and Chaos Powers to the point where his Chaos Blast could decimate the entire city of New Mobotropolis, briefly fight back Enerjak and divert a laser with enough power to destroy half of the Eggdome with Chaos Control.

Trivia

 * Capturex.JPG official name for this transformation was unknown up until the Sonic FCBD 2009 special where it is stated in a datafile that this form was named "Chaos Shadow".
 * While never referred to as "Chaos Shadow", Shadow receives a huge power boost whenever he takes off his Inhibitor Rings in the Sonic the Hedgehog series. So far, he has only used this power against Mephiles the Dark in Sonic the Hedgehog (2006).
