Mutation of Fading

"We come. We slowly fade. That's how life works."

Shawn and Abigail Langston were one of the Kraang's main experiments. They have been tortured, cut open, and zapped at. But one day they escaped. They live off of the streets and became city wide vigilantes known as "the Phantom" and "the Spirit". They have the ability to go through walls and manipulate the minds of their enemies. Their main goal: destroy all Kraang infesting the city.

But would happen if they ran into four ninja turtles? Would they continue down their dark path to inialte all Kraang? Or would their plan would just fade away?
