The summer blockbuster season is well and truly upon us now, and it’s a summer of heroes. Of the many comic book movies coming out this year, Jonathan Liebesman’s Teenage Mutant Ninja Turtles might be the one that fans have the most mixed feelings about. Some are just excited to see the heroes in a half-shell get their own big-budget live-action movie, while others have been put off by the involvement of Transformers helmsman Michael Bay (here, as producer).

The trailers so far have only served to divide opinion even further and it wouldn’t be surprising if the final fan verdict on Teenage Mutant Ninja Turtles ends up being split as well. At the very least, the movie has the potential to make a lot of money at the box office thanks to the combined interest of nostalgic children of the 80s, kids who are currently watching the show on Nickelodeon, and other miscellaneous moviegoers who just want to see a popcorn movie with friends.

For those seeking an extra dose of hype, Instagrammer WestCoastGeek has spotted some stylish new characters posters for Teenage Mutant Ninja Turtles while out and about, featuring Raphael, Donatello, Michelangelo and Shredder. There’s also a Leonardo poster, but unfortunately due to the framing of the images we only get to see one of his hands and his twin katanas.

UPDATE: Here are official versions of the street art posters!

The Wolverine also had some character posters with a similar style to this, though these posters seem to be more designed to look like street art. Perhaps the turtles themselves sneak out of the sewers at night to leave pictures of themselves on local buildings – though since these posters were spotted in LA, they probably don’t count as “local.”

The turtles themselves have been seen enough in the trailers and posters, but their mentor Master Splinter and nemesis Shredder have yet to be shown in their full glory, outside of concept art. Although heavily stylized, the poster for Shredder suggests that the design shown in concept art for Teenage Mutant Ninja Turtles mostly made it through to final concept and the alter ego of Eric Sachs will be a sharp and pointy force to be reckoned with.

Teenage Mutant Ninja Turtles is out in theaters on August 8, 2014.
