Jackal Squad, also known as Squad Jackal, is a group that appears in the Sonic the Hedgehog series. It was a group of thieves and mercenaries led by the so-called "Ultimate Mercenary", who would eventually become known as Infinite.
The Jackal Squad was hired by Dr. Eggman to serve as a defense squad whilst he studied the Phantom Ruby. Most of the unit, however, would later end up defeated by Shadow the Hedgehog, with Eggman, while contacting their leader, demanding that he go clean up their mess while decrying them as useless.
- The group was called the Jackal Squad by their leader before becoming Infinite in the digital comic, Sonic Forces: Rise of Infinite, but was called Squad Jackal by Dr. Eggman in the downloadable prequel scenario, Episode Shadow, in Sonic Forces.
- The only member of Squad Jackal to have dialogue besides their leader is an unnamed character wearing a bandanna who attempts to dissuade their leader to align with Eggman.
