Concept and creation
Chuck appeared for the first time in issue #0 of the Sonic the Hedgehog miniseries published by Archie Comics, back in February 1993. He would've later appeared in Sonic SatAM in October 1993. After one last appearance in Sonic Underground he remained an exclusive character of the Archie Comics in both continuities.
After Yeager Hedgehog left his family from which he never returned, Chuck took Sonic with him and helped his nephew to increase his skills. When Sonic turned 14 years old, Chuck and his sister Aleena let their boy leave for a trip to South Island.
- Chuck was not related to Aleena in Sonic Underground and he was Sonic's paternal uncle in the Pre-SGW Archie continuity.
