I'm pretty sure that both Slash and Newtralizer will join the turtles and help them combat Shredder and the Foot Clan sometime in the near future.

If there was a fight between Leatherhead and the Newtralizer, how would you react?
you know, a spin off that would take place after Metalhead Rewired or even during season 3
where the most powerful mutant titans bound together to fight threats no-one not even the turtles can face
i dont mean to bring a spoiler but they might take charge over the city when the shredder forces the turtles to leave.
The Turtles greatest allies!
