User blog comment:Kung fu frogz/What I want to see in the TMNT sequel. (May contain spoilers)/@comment-16436805-20140817141708

Here's what we need for the sequel.
 * Eric Sacks as the new Shredder. He said he was trained but we never see him fight it would be great if he took his master's place
 * Karai with a bigger part in the movie, no more of that Tatsu bullshit, she's a strong character and should be used as one. It would be good if they revealed she actually was his daughter and now she wants revenge against the turtles, no matter the cost
 * Baxter Stockman showing up and saying that all of Sacks money came from HIS inventions, and now he takes over Sacks industries, changing it to Stockman industries (but keeping the S symbol).
 * April was fired and she never got her job back, now she could be working on Second Time Around or as a lab assistant for Stockman (not because she's a genius or anything but because of her connection with the turtles).
 * Casey Jones, he must be someone extremely buffed up so he can stand against the new muscular Raph (someone with The Rock's body type would be good).
 * A better villain plan, cuz... You know.
 * NEW MUTANTS, with Baxter on top of the former Sacks group Ltd. he could get more mutagen from a "mysterious benefactor" - Krang - but Baxter is not a bad guy (yet), he was inspired by the turtles and now wants to actually create more heroes. What he doesn't know is that Krang wants him to create new mutants so he could build an army and conquer the planet.

And of course, having Krang involved would include transdimensional portals, which at the end could take us to the beginning of the third movie, Turtles in Space! Cuz we seriously need live-action Triceratons.
