'''NOTE:''' Due to the events of ''Sonic the Hedgehog'' #251, some profiles may be out of date. There are also several characters who can no longer appear due to litigation with former writer Ken Penders, who claimed copyright on several non-SEGA characters.
If [[https://sites.google.com/site/sthcharasbyauthor/home this]] is to be believed, then it should be pretty easy to flag the characters who (likely) won't be showing up anymore.
On October 26, 2013, during a streamed broadcast for the Sick Kids Foundation charity, Ian Flynn offered to answer questions. He clarified, however, that he could only discuss characters and concepts from the Sonic video games, the Saturday Morning cartoon, and The Adventures of Sonic the Hedgehog. He has repeated this on his own forums, indicating that he cannot answer questions regarding other characters. Based on this it would appear that all characters created by previous authors are off-limits, as are any characters Flynn created that were based on material written by previous writers.
