As per the legal settlement of the case, new and increased mandates from
Sega Incorporated were put into effect in any and all
Sonic the Hedgehog related contents, including (but not limited to) games, television series, films, toys and even
comic books. For Archie's
Sonic the Hedgehog comic series specifically, as relevant to the legal case, the following mandates in effect are (but not possibly limited to) as follows:
- Sega-specific original characters are not permitted familial relationships unless already established (like Cream the Rabbit and Vanilla the Rabbit) with some limited exceptions (eg. Charles Hedgehog). ACP-exclusive characters (Sally, Rotor, Bunnie, Antoine) are permitted however.
- Use of Ken Penders characters or any of his content from the Pre-Super Genesis Wave are forbidden (although settlement grants ACP legal use of his creations under limited conditions, reasons for not doing so are not disclosed to the public by either ACP or Sega Inc. as of this time).
- Content from certain games are not permissible:
- Replacing said characters with post-incarnations however, is permissible. (eg. Maximillian Acorn → Nigel Acorn).
- Archie Comics Publishing are forbidden to reference Sonic the Hedgehog: The Movie, Sonic Underground or Sonic X unless granted specific permission from Sega Incorporated.
- ACP is forbidden to using the character Doctor Eggman Nega unless specifically granted permission from Sega Incorporated.
- Sonic's home planet is no longer permitted to be referred to as “Mobius”, be it Light, Dark, Prime or otherwise.
- Only one Metal Sonic is permitted for appearance but no multiples.
- With the exception of the character Nicole allowing effected characters to remember the previous universe, these memories are forced to 'fade' and be rendered irrelevant.
- Character depicitions such as Classic Sonic, Classic Tails, Classic Eggman or any other classic depictions of Sega's characters are not permitted unless permission is given directly from Sega Incorporated. (However some ACP publications have shown scenes of the 'Classic' characters in shadows, silhouettes or bare resemblance to them in flashbacks). With the 25th anniversary of the Sonic the Hedgehog franchise however, this mandate appears to have been lifted.
- Sonic is not allowed to “lose”. He can be 'put down' and experience hardship but is not allowed to completely 'fail'.
- Main and/or significant characters are forbidden in forming intimate or love-relationships. ACP-exclusive characters are permitted however (Bunnie and Antoine) but not with Sega's characters (Sonic the Hedgehog and Sally Acorn).
- Original Sega characters are to conform, stay conformed to their modern designs as of Sonic the Hedgehog #71. None are allowed to change or modify their existing wardrobe or wear any different wardrobe at all, regardless of the story context.
- Sega-exclusive characters cannot be "killed-off", whilst Archie-exclusive characters are not mentioned in this mandate, it remains unclear whether this rule may apply to them also.
- Sonic and Sega-exclusive characters are not allowed to show excessive emotion.
