After watching this ep again I might have to say this Shredder is the worst of all. Like he was really proud of himself that he destroyed the world just to kill Splinter while his back was turned. He's literally done all of the things all the previous or other current Shredder's have. The current comic Shredder captured and brainwashed Leo and turned him on the turtles, also during the Kraang invasion betrayed Donnie and had Bebop and Rocksteady try to kill him. This Shredder helps the Kraang invasion, brainwashed Raph and turned him against his brothers, kills Splinter while he's about to prevent the destruction of the Earth. 03 Spredder caught bodies, this one caught bodies
03 tried to destroy the multiverse just to kill the turtles. This Shredder actually succeeded in getting his world destroyed.

why
are Splinter and Shredder s much more powerful than everyone in the universe. Both of them were taking out Triceratons easily
they both can easily take out Leatherhead,Slash, Tigerclaw, Rocksteady, and all the other heavy hitter that have appeared on the show. I think after this Tigerclaw is going to turn on Shredder when the turtles fix everything. He was questioning Shredder's motive and Karai when they were trying to kill Casey and when they torture Mr. Morigami to find out the turtle's where-abouts season 2, plus he and Karai questioned Shredder's honor when he tried take Splinter when he was poisoned, and he wasn't down for helping the Kraang invasion. I think this might be the last straw that he cares more about revenge than his subordinates' lives and his kidnapped daughter.
