With Splinter and Serling arrested by the Peacekeepers, Cody must find the Turtles before it's too late.

Quotes

 * Dark Michelangelo - "Clones from your tissues, but with lots and lots of issues!"
 * Leonardo - "If you are my clone, you should value the ways of bushido... of honor!" Dark Leonardo - "My brothers and I share many similarities with you and your siblings. But valuing honor, not so much!"

Miscellanea

 * First appearance of the Dark Turtles, whose skin colors match their facemask colors, with the exception of Dark Mikey, whose skin is yellow.
 * Dark Donatello's snooty behavior is similar to that of the clone Don made of himself in the original cartoon's episode "Donatello's Duplicate" from 1991. In that story though his clone was an enhanced replication that looked and sounded exactly like the old toon Donatello, unlike the fanged, long-tailed purple monster here in 2105.
 * The Dark Turtles' lair is highly a corrputed version of their second lair (similar to the fact that the Dark Turtles are corrput versions of the Turtles).
