Aw man, this sucks not only for the fans, but also for the artists that are going to have to look for work now.
And to Ken Penders ---
Get bent, you Sonic-OC copyrighting, trademark trolling piece of scum.
If you don't know who Ken Penders is, he's the reason the comic started to die.
This rotund wank was hired in the 90s to do the Knuckles the Echidna stories (They SUUUUUCKED). In 2009, he secretly copyrighted the (original the) Echidna characters and decided to sue Sega and Bioware over Sonic Chronicles' echidna characters.
Penders lost, then sued them again, and lost with prejudice.
Then, Penders turned to suing Archie for ownership of the Knuckles series, as well as the echidna characters.
This time, the little troll decided to use a contract that Archie lost in an office fire against them. Archie agreed to settle out of court, and were forced to retcon and reboot the entire series of comics, removing each and every one of Ken Pender's precious OCs.
Then, Sega, sweating its britches in fear of more lawsuits, imposed new strict guidelines for Archie. Such as, no crying, no strong emotion, no romance, etc.
What's worse is that in the new Sonic game, Sega decided remove the option to be make the Custom Hero an echidna.
This lead to more and more collapsing of the Sega-Archie partnership -- long hiatuses, retconned pages, Archie killing off other comics to focus on their new Riverdale series, etc.
And now, the death of the Sonic comic.
Now, you might be wondering, what did that Ken Penders fellow do with his precious OCs?
Well....
This is meant to be sold to kids, by the way.
TL;DR Work for hire hack sued Sega and Archie for his ORIGINAL Knuckles the Echidna OCs (DO NOT STAEL) and started the steady death of the Sonic Comics.
