Sleuth Dawg

Originally a member of the Freedom Fighters operating undercover in Robotropolis, Sleuth 'Doggy' Dawg was swayed to Dr. Robotnik's side by promises of wealth and personal power. His attempted coup against Princess Sally Acorn was unsuccessful, and he was incarcerated at the Devil's Gulag prison. Upon his escape, he teamed up with several other prisoners to take his revenge, but they were Roboticized by Eggman. After their De-Roboticization, the group had robot duplicates of themselves created by Anonymous, and recordings in the wreckages of these machines showed the Destructix dealing with Anonymous.

Doggy joined his teammates in an attack on Knothole Village in an effort to recover the Chaos Emerald containing Mammoth Mogul. After their defeat and reincarceration, they were liberated by Mogul, and engaged the forces of Ixis Naugus in battle briefly before teaming up with the wizard against the Freedom Fighters and the Chaotix. Doggy and his allies were afterwards attacked imprisoned again, but later escaped courtesy of Dark Legion renegade Dr. Finitevus. Doggy later appeared alongside Scourge the Hedgehog, working under Finitevus' orders. During this battle, he made vague reference to Fiona Fox being a traitor. Not long afterwards, he joined the other Destructix in assisting Finitevus' plans for seizing control of the Master Emerald, thus facilitating the return of Enerjak.

Due to being situated on Angel Island on the time, Doggy and the others were not among those criminals fooled by Rouge the Bat's sting operation. The list of their fellow fugitives who were captured in the operation included Mogul, Naugus, Nack the Weasel, Bark the Polar Bear, and Bean the Dynamite. In addition, Doggy and the rest of the Destructix were not among those transported to the Egg Grape Chamber, a fate that befell both their imprisoned colleagues and most of the Freedom Fighers and Chaotix-though all of them were rescued soon afterwards by Sonic, Knuckles, Tails, Amy Rose, and NICOLE. He and the other Destructix were later in position to challenge Locke, Sonic, and Knuckles' girlfriend Julie-Su when they arrived searching for a weapon to use against Enerjak.

Somewhat more brutal than most of the secondary villains, Dogg was able to hold out against Robotnik's Roboticization longer than the rest of the team. When it became clear that he was beaten, he attempted to blow them and himself apart with a hand grenade. Like Drago, he is willing to sell out anyone so long as there's something in it for him, and he also appears to have little backbone when it comes to employers who intimidate him into doing their bidding.
