A few days ago, the website
teenagemutantninjaturtles.com posted images of a Michelangelo Halloween costume that was designed based on the new look of the character for the Michael Bay-produced
Teenage Mutant Ninja Turtles live-action film. A user on Reddit,
stoudman, has claimed that he originally posted that article and has seen the other three Turtles. Take it with a grain of salt if you like, but here are his descriptions.
Leonardo has a somewhat ethnic looking breastplate, but other than that he's pretty much exactly what you would expect. Raphael has a bandanna that covers more of his head than the rest, as well as sunglasses on his forehead, but is probably the most normal looking of the bunch. Donatello...is an offensive geek stereotype. He's wearing the "nerdy" glasses with the tape in the middle and some sort of high tech goggles on his forehead (much like Egon); His shell literally looks like a proton pack, with several gadgets and tubes running around it. I'm not sure why.
No, they all have loincloths -- except Mikey, who is wearing a sweatshirt around his waist. - stoudman
