True, Knuckles' original creator was Takashi Thomas Yada (For SEGA games, when Sonic the Hedgehog 3 was in producing), not Ken Penders. Though I don't know who redesigned Knuckles' future version as seen in "Mobius 25-Years-Later" issues.

And yes, Ken's the stubborn dude, refuse to accept that Knuckles belong to SEGA, along with Geoffrey St. John. Hell, Ken renamed Knuckles into Praetorian, and he still look like Knuckles to me. I can forgive him if he said that Praetorian is the alternate version of Knuckles, but he didn't say anything about that in twitter.

he claims he drew thatr image of knuckles and becasue he drew it he has fair use..once again he claims it..

all his charicters still look liek sonic charicters..this "graphic novel" as he claims is nothing more bthan poffical fan fiction now one is going to buy it

Yeah, two of them were copy/paste, with exception of Lara-Su (only her name was inherited) as well as gained a new character, who "summoned" Geoffrey St. John.

But hey, if he claimed that Praetorian is an alternate version of Knuckles, not ripoff of him, then I can forgive him. I once ripoffed one of my dA friends' characters and killed her, only to make her anger and left dA. I later learnt my lesson for make her leaving the site and now considered that storyline as alternate instead.
