The Nasty Hyena Gangs are groups mentioned in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They were a biker gang based in Efrika which was also home to the Bear Pack gang.
At some point, the Nasty Hyena Gangs and the Bear Pack were united under the leadership of Diesel, who became their Grandmaster when the united group joined the Efrika chapter of Dr. Eggman's Dark Egg Legion.
- The Nasty Hyenas were introduced in the Sonic the Hedgehog animated series episode "Fed Up with Antoine", in which they appointed Antoine Depardieu their king whom they planned to eat had Sonic not intervened.
- They are among the only characters not to have been originally created in the comic series who ended up as members of the Dark Egg Legion.
- Following Worlds Collide and the ensuing reboot of the Sonic comics, Ian Flynn stated that he had no plans to incorporate the Nasty Hyena Gangs in the new reality.
