I do get what you mean. For example, Sonic fan artist Jennifer Hernandez has a group of fan characters she calls the Jewel Carriers. Crystal the Cat being one of her more used characters.

In issue #282 of Archie's Sonic the Comic Crystal the Cat can be seen and in #3 of IDW Sonic the comic she is seen againalong with other JC characters.

The reason why these characters have appeared in two issues is because Sega, or the very least Archie and eventually IDW, hired Jennifer Hernandez to be lineartist to some of the comics, so she obligated herself to insert her characters just for background cameos.

As for other fan characters in Archie and IDW comics, likely due to those issues being done by artists who were formerly just fan artists of the series.
