Oh, man, another Lia stream that I'm on the edge of my seat for. I absolutely love these streams she's doing. (Hopefully this one involves less watermelon anal insertion.)
Quick summary on this guy: He was the writer of the long-running Sonic comic published by Archie who, due to a lack of oversight from Sega or Archie, ended up taking the story into some really bizarre directions involving characters merging with each other, alternate dimensions, complex romantic relationships with allusions that the characters were bonking off-screen, etc. He loved Knuckles and spun off dozens and dozens of other echidna characters. Eventually Sega saw what was happening and had Archie dump him and reboot the comic continuity into something more akin to what you would expect from brightly-colored animal friends fighting robots, but Penders, with delusions of grandeur, started doing crowdfunding to continue making comics about his echidna OCs, prompting legal attention from Archie. (I probably misremembered half of these details but it's something like that.)
