What if they were Cyber Turtles until the end?
 

Not just one episode, but the for the rest of the show. I'm surprised they didn't make the show similiar to the TMNT anime. Heck, why not have red sky Krang transform Bebop, Rocksteady, and Shredder into cyborgs and fight the turtles? We would of had those villains in more episodes instead of a few.

It worked in Archie because they were in the future and fighting villains who they needed the armor for.

In present day New York that Cyber Armor looked very out of place. It was good for one episode but that's it.

I would have liked it. Definitely would've made for more great toys.
