Appearance

Biography
Shadow and Diamond used to be friends when they were young, and they eventually started dating. One night, while Diamond was riding Shadow's BBC, she fell over funny and broke his dick off. The doctors could not save Shadow's dick, and so he had to get a vagina as a replacement. From this day forward, Shadow has been antagonistic to our heroes, vowing to stop them from gathering the 7 Chaos Emeralds.

Diamond Blood Boom the Fox
Diamond and Shadow were once in a relationship when they were both young. Ever since the dick-breaking incident, Shadow has acted ambivalent towards Diamond, although it could be possible that he still has feelings for her.

Zoosnuck the Hedgehog
Shadow dislikes Zoosnuck greatly, mostly for his snarky remarks and racist comments, but also because of his crimes against Chaos. Shadow considers Zoosnuck to be his greatest rival.

Rouge the Bat
Rouge appears to be Shadow's caretaker. It seems that Shadow respects her a great deal, as he allowed her to steal him forever with very little objection.

Abilities
Shadow's powers come from the power of Chaos, as well as just how edgy cool he is.

Chaos Control
Shadow has control over the powers of Chaos, moreso than Zoosnuck, and can teleport anywhere at will. He can even sense the location of Chaos Emeralds with this power.

Shadow Disguises
One of Shadow's most unique abilities, he can alter his appearance to become a shadow clone of anybody. So far, he's disguised himself as Dr. Eggman, Zoosnuck, and a mysterious clown with a machete.

Chaos Spear
When Shadow possesses one or more of the Chaos Emeralds, he can perform Chaos Spear, shooting a long beam of pure energy into his opponent.

Kill Everything
When Shadow has a certain amount of Chaos Emeralds, he can simply kill everything, creating a large, powerful explosion that will destroy everything in its path.

Trivia

 * Despite his defeat in Chapter 5, Shadow makes a brief appearance in Chapter 6, plotting how to take down Diamond Flowey with the rest of the gang.
 * It's possible that this Shadow was an illusion/clone. This is supported by the fact that his head rolls off while nodding.
