Despite the news that Eric Bauza will be portraying Master Splinter and Rob Paulsen will be taking over as voice director, I still have reservations about Rise of the TMNT, the new series debuting in 2018. (Raph ain't no leader.)
As much as I complained about the 2012 series, I feel like it wasn't beyond saving.
So, if you'll indulge me and my fanboyism and poor grammar, here is what I would do if Nickelodeon had said to me "Hey. Write us a season."

The Turtles discover the Silver Sentry is in actuality, a young pizza delivery boy named Carter, who can only keep his Silver Sentry form by absorbing mutagen - and he's eyeing the Turtles. Snakeweed attacks the Sentry and manages to wound him. Donatello devises a serum to help Carter's Mutagen dependency, but not before Carter cures Mutagen Man of his mutation.
