Several HEXAeco facilities were briefly seized by Metal Sonic while he impersonated Dr. Eggman as head of the Eggman Empire. Team Sonic, Team Dark, Team Chaotix, and Team Rose all passed through HEXAeco facilities during their efforts to stop the villainous robot. Later, during the Shattered World Crisis, HEXAeco would step up as a sponsor for Breezie the Hedgehog's Chaos Emerald Championship.
- HEXAeco is based on the company that appeared in the setting for Grand Metropolis and Power Plant Stages in Sonic Heroes.
