Ken Penders, best known in the Sonic community for his comic book run and Sega lawsuit, is threatening further legal action after the release of Sonic the Hedgehog 2.

As a result, he says he wants his attorneys to "discuss" the matter with Paramount producers, and hasn't ruled out another lawsuit.
Penders, who admits he hasn't seen the film, takes issue with Knuckles having a father in the film's version of his backstory. He goes unnamed, and all we learn about him is that he was the leader of the echidna tribe, and died trying to reclaim the Master Emerald. Penders says that this character is actually his - referring to Knuckles' dad in the comics, Locke. He also says the producers used his character Enerjak as an inspiration for the Master Emerald's ability to grant the user powers, even though the film never mentions the emerald containing the spirit of a living being.
