The Beginning of the End

[leader in blue]

I just finished the 87 series i never saw the red sky seasons as a kid so they were new to me

in the beginning of the end episode the bad guy dregg transformed Leonardo into a monster i guess i don't know how to describe it but im sure everyone knows what im talking about at the end the other turtles were able to cure him returning him back to normal but then the bad guy(s) who were spying on the turtles via cambot stated that although Leonardo looked normal he had permanent altered Leonardo's genetic structure and he would use it to his advantage but then 6 episodes later the series ends without another word about it

i was intrigued by this though i wonder what they were planing with this were they hinting that Leonardo could be dying or maybe turn him into a sleeper agent so to speak
