Because that's not MY Knuckles Cubee.. I make the characters/Cubees I want to make regardless of what's already been made by Chris Beaumont and the other Cubee crafters... My Cubees are also hand drawn and not done with Illustrator or the various other computer programs out there to make that... I feel it's only appropriate to do a version in my style instead of using other's creations to go with my own... (as a side note, there's also a Dr. Robotnik Cubee available).
