Are you pissed that Ken Pender's characters can't return unless they return by miracle standards? Then these are great options on replacing those characters.
1. Character Merges.
- Julie Su should be replaced with a Female Echidna that is really beautiful and has ninja abilities.
Like this Female Echidna named Ember the Echidna.
- Scourge the Hedgehog - He should be replaced with Nazo the Hedgehog or Ashura the Hedgehog taking his place as Sonic's evil clone.
Nazo the Hedgehog
Ashura the Hedgehog
- Fiona Fox - She should be replaced with a replica of Sally Acorn who looks like Alicia Acorn (the original Anti-Sally).
Appearance of Alicia Acorn in which whom this Fiona Fox replacement should look like
- Lein-Da - She should be replaced with a beautiful female anthropromorphic animal of any kind who could be a great henchwoman of Eggman especially the fact they will have the same personality as Lein-Da.
These would be great appearances for a potential Lein-Da replacement.
- Geoffrey St. John - Should be replaced with Aeon the Hedgehog
Appearance of Aeon the Hedgehog
- Hershey Cat - Should be replaced with a popular Female Sonic fan Character.

2. Have Freedom Planet merge with Sonic
This a great solution in my opinion due to the fact there are multiple Sonic/Freedom Planet Fan-fictions like Sonic x Freedom Planet: Power of Chaos

So these are two potential solutions for replacing Ken Penders Characters if IDW decided to bring back the SATAM and Archie Characters,
