The bad guys of the iconic mutant franchise were spotted on the sequel's set for the first time on Tuesday 26th May 2015.
Shredder was back, this time played by Brian Tee, and he was joined by iconic criminal duo Bebop and Rocksteady in New York.
Enter the Shredder: Brian Tee was seen on the New York set of Teenage Mutant Ninja Turtles 2 as bad guy Shredder for the first time on Wednesday
While fans will no doubt be very excited to see the twosome, who did not make the cut for the 2014 release, the baddies looked very different.
Namely they were not mutant Zoo animals.
In the original 1980s cartoon series and Nickelodeon's hit CG-animated "Teenage Mutant Ninja Turtles" series, Bebop and Rocksteady being portrayed by Gary Anthony Williams and pro wrestler Sheamus in TMNT 2, are a humanoid Warthog and Rhinoceros, respectively.
Double trouble: Beepop - played this time by Gary Anthony Williams - and Rocksteady - portrayed by pro wrestler Sheamus - also made their debut
Changing things up: In the original 1980s cartoon series they were a humanoid warthog and rhinoceros but their mutation may be part of this film's plot
There is still a chance that fans will be able to get nostalgic as everything else about the pair seemed to match the original, suggesting they may be turned into mutants as part of the storyline.
For the day of filming, the pair was seen conversing in a cafe with Gary Anthony sporting Beepop's iconic purple mohawk.
The characters were meant to appear in the first film but were then written out with the intention of them bringing something new to the sequel.

The two bad guys form part of the ultimate bad guy Shredder's Foot Clan.
The new Shredder was on set for the first time on Wednesday also.
Stepping as the head bad dude, Brain was dressed in full battle worthy leathers with the character's signature spiked arm guards - which appeared to have the razor sharp spikes retracted - along with metal shin and knee guards.
He was not wearing Shredder's scary helmet and face mask as that is no doubt the last piece of the costume to go on before filming.

Just hours after it was announced she was joining the film, Brittany Ishibashi was also on set.
The 34-year-old actress will play Shredder's daughter Karai and was dressed in a female version of her on-screen father's look.
The form fitting body suit features leather breast as well as leather panels on her shoulders, arms and legs.

The formidable force of bad guys will be, of course, facing off against the Teenage Mutant Ninja Turtles and their reporter pal April, played by Megan Fox when the film hits theatres June 3, 2016.
Also returning is Will Farell as Vernon Fenwick, who gets a new love interest in supermodel Alessandra Ambrosio.
Other new cast members include Laura Linney, Stephen Amell and Tyler Perry as the evil humanoid fly scientist Baxter Stockman.
