Sonic X
The American comics published by Archie Comics, "Sonic the Hedgehog" (1993–2017), "Sonic X" (2005–2008), and "Sonic Universe" (2009–2017) are based on the settings established by earlier animated TV series, the ABC "SatAM" cartoon, the "Sonic X" anime, and an expansion to the series, respectively. The former series is currently the second longest-running licensed comic series in the history of American comic books, second only to Marvel's Conan series (first issue released in 1970).
