STHRPs is a ProBoards RP group that has both a SEGA and SatAM division - and fan characters are welcome!
There are some restrictions - due to the large number of fox, echidna, and hedgehog fan characters out there these species are limited, as are Super forms and characters who can use special abilities without the aid of an Emerald - but there’s a wide variety of roles for you to play, as well as several canon characters still available.
(And you can also adapt characters from other Sonic media to either division - Mod Nikki currently plays Antoine in the SEGA division, and Bunnie is present there as well!)
It should be noted that most players are 20+; while the board is rated T/PG-13, that is something to keep in mind when you apply.
