Team Dark (IDW)

Team Dark is a group mentioned in the Sonic the Hedgehog comic series published by IDW Publishing. It is a team consisting of Shadow the Hedgehog and Rouge the Bat.

Past
When Dr. Eggman went missing after the war between the Resistance and the Eggman Empire, Shadow began searching for Eggman to eliminate him. Knowing that the Chaotix, who were looking into Dr. Eggman's whereabouts, were in danger in case they crossed paths with Shadow, who would hurt anyone getting in his way, Rouge secretly led the Chaotix to Eggman in time for them to conduct a full investigation of Eggman and bring in Sonic, who would act as a countermeasure for Shadow. Eventually, Rouge "helped" lead Shadow to Eggman.

The Fate of Dr. Eggman
Approximately a month after the Resistance-Eggman Empire war, Shadow and Rogue found a seemingly amnesiac Dr. Eggman in a village, dealing and becoming friendly with Sonic and the Chaotix. After Eggman mentioned Eggman Land however, Team Dark revealed themselves, with Shadow declaring that he would destroy Eggman.

While Shadow was led away from Eggman by Sonic, Rouge was confronted by the Chaotix, who accused her of bringing Shadow here. In her defense, Rouge revealed that she had been managing everything to ensure the Chaotix's well-being and successful investigation. In the meantime, Sonic convinced Shadow to give Eggman a chance to explain himself, seeing as his amnesia had made the doctor a good man. By the time Shadow returned, Rouge stood ready to defend Dr. Eggman as well. However, she let Shadow pass after he revealed that he had talked the matter over with Sonic. As such, instead of eliminating Eggman, Shadow had Eggman show him Eggman Land, which turned out to be an amusement park for children that Eggman had made. Convinced that Eggman was now a good man who deserved to be forgiven and live in peace, Team Dark took their leave.

The Battle for Angel Island
Eventually, Shadow and Rouge were called to Resistance HQ. There, they and the Resistance's other allies were informed that the Resistance needed their help to liberate Angel Island, which had been conquered by Neo Metal Sonic and turned into a flying fortress. To make matters worse, Neo had also taken control of the Master Emerald on the island. Eventually, Team Dark were assigned to help two of the assembled group's factions with breaking the Egg Fleet's control over Angel Island while Sonic and Knuckles confronted Neo.

Using a Resistance battleship, Team Dark and their allies came under fire by the Egg Fleet when they began approaching Angel Island. Fortunately, they and their allies got off the ship before it crashed and made to Angel Island. Once there, Shadow went off on his own while Rouge followed orders and began handling the guns.
