Shadow Squad

The Shadow Squad were a group of galactic variants of Shadow the Hedgehog from various galaxies that had all been arrested and sent to Prison Galaxy. They were all defeated and killed by Super Sonic Level 4.

Members
The leader of the Shadow Squad is Shadovamp the Werebatmanhog, a female werehog Shadow that is supposedly a fusion of 10 different Shadow variants. The next most notable member is Shaduwu who has the most latent power. Deviledge the Killhog is the most vocal and dominant member of the group, often acting as a leader when Shadovamp is not around. Dan the Emohog is a quiet, depressed and mellow variant, and finally Shadow Underground, from the Underground Galaxy.

History
How each and every one of these Shadows were arrested and sent to Prison Galaxy is unknown. Each of them seems to be as strong as or more powerful than Run, especially their leader. They all apparently took turns dating Valentine the Mink while serving as inmates at Prison Galaxy. They met Run and Duck after Valentine was smacked onto their lunch table. After fighting with Duck and Run, Shadovamp arrived and proved herself to be much stronger than Run, but was quickly defeated by Valentine. Later, Shadovamp challenged Run to a rematch, but Run had grown in strength by feeding off the Chaos Energy of the emerald shards within the prison walls, and was able to overpower her with ease. When Run explained he planned to break out with Think the Stink, the Shadow Squad trained Duck the Duck until it was time for the prison break.

Each member helped to fight against the prison guards and all eventually combined their strength with Run to defeat Prisonic the Hedgehog with a Chaos Blast attack. After the supermassive black hole absorbed the entire galaxy, including all the emerald shards, Shadovamp used her stretching ability and strength to crush the black hole into a single diamond. While that was happening, the lesser members of the Shadow Squad each fought off Super Sonic Level 4 and lost. Shadovamp handed off the chaos emerald to Think and Run, and then also died against Super Sonic Level 4.

Powers
The average power level of Shadow Squad members appears to be similar to or greater than Run's strength, each able to destroy a galaxy or more. Shaduwu was able to destroy 50 galaxies at full power, after absorbing the energy and matter of 20 galaxies around him. Shadovamp is supposedly stronger, but her fighting prowess is reduced to physical attacks and strength. Each Shadow Squad member is capable of using Chaos Blast as well as other chaos abilities.
