confirmed There will be a Possible Sequel Hook on Season 3
Since that there is a possibility that if the movie ends up being positively, it’s likely that a possible Season 3 will happen.- Not an outright Sequel Hook, but Krang 1 is left trapped in another dimension at the end of the film, so there's a chance if a third season is made, he will be the Big Bad.
Post-Release
The Shredder Armour was a Krang Exosuit.
The Weeping Titan in Season 2 having the skeleton of a Krang inside it and the Shredder being drawn to it, in addition to the very similar design of the Shredder armour and the Exosuits used by the movie's Krang makes this feel like a pretty safe bet.The Krang are the same version of the species seen in the 2012 series.
Krang 1, 2, and 3 are members of the same Kraang species seen in the previous Turtles series, where they were established as being an ancient Hive Mind of multiversal conquerors. The trio's relative individuality can be explained either as a side effect of their long imprisonment in a pocket dimension or as a result of the Kraang experimenting with more independent agents like Kraang Sub-Prime. They may be from much later in the species' personal evolutionary timeline, given how they've clearly taken a major level in badass. One wonders how other incarnations of the Turtles would fare against them... The Krang all killed each other during their imprisonment.
You can't make the argument that it was sickness or starvation that killed them, as the three Krangs we see are doing just fine the moment they find themselves on Earth. All we know is that the remaining Krang aren't all that broken up about being the last of their kind and Krang One is always espousing that Might Makes Right, so it is likely that with no other species to torment and destroy, they all turned on each other and culled each other until the three remained. It's the sort of thing you'd picture the Daleks would do in the unlikely event that they succeed in their mission to wipe out all other life in the universe. The dimension the Krang were all banished too was Dimension X.
Not the same Dimension X as The Kraang obviously, but since Dimension X is never mentioned and The Krang are stated to have come from space, it's likely that the Krang originate in a far-off galaxy of Earth's dimension and were banished to Dimension X by the Ninja Mystics. Sequel Theories
Krang 1 will be the new Big Bad of Season 3
He will definitely want revenge on the Turtles for stopping the invasion. As an added bonus, the dimension he's stuck in will be the Rise version of Dimension X.Michelangelo's portal powers will lead to the traditional crossover with Usagi Yojimbo.
Before Rise was Screwed by the Network, it was common for every Turtles cartoon to feature at least a few appearances by Usagi. Now that there's a possibility this show might return, and Mikey can open portals to other dimensions, that could provide a good excuse for the Turtles to meet Usagi and his cast. Or maybe they could meet Yuichi Usagi, since his series also dealt with yokai and other dimensions, and is also on Netflix.The Earth Protection Force will become major antagonists in a potential Season 3.
Due to their blatant cameo at the end of the movie whilst detaining Krang 2.Had the series continued and gone on longer, all four Rise Turtles would have achieved power levels comparable to the strongest anime characters in Tengen Toppa Gurren Lagann and many others.
The series is already heavily inspired by anime and there are moments, such as the final battle against the Shredder where he creates a drill to battle them and that moment where the team posed with an explosion and a drill in the background as Shout-Out moments to Gurren Lagann. If the series didn't get cut short, the Turtles would've gotten to the point where they might legitimately be able to hurl galaxies as shooting stars, shrug off supernovas, destroy celestial bodies, and tank attacks comparable to the Big Bang. They're already enough of Adaptational Badass characters as-is but just think how much more they might've achieved if the series wasn't discontinued.The sequel will actually be rated by the MPA.
And feature the current MPA logo instead of the old one.
