Thats already a lot more effort in including new characters compared to IDW in my opinion.>The other Eggman Dozen where made of old characters or new ones that only showed hints of possible development that never really came to fruition.
Yeah, aside from Cassia and Clove, the other egg bosses had more of a promise of being good characters instead of being developed.
But that doesnt mean the way they were presented didnt make them interesting to the readers.
They also had some defining personality or background that made them stand from eachother as well.
Would you call that neutering, or just underdevelopment ?
Also, I think the pirates from the chaotix story fit into the above as well. Ian obviously had something planned for them in the future.
As for the rest of the reboot only cast, maybe Phage ? But then, she felt like just a robotic villain made for Nicole.
