Stiles Stilinski loooooooooves to track down a Teen Wolf villain -- and now Dylan O'Brien's newest film role will feature the actor partaking in the same type of activity.

The 25-year-old -- who's returning to the long-running series on November 15 -- is starring in the action-thriller American Assassin. Fortunately, we don't have to wait for a trailer to get a peek at the New York native in action: The motion picture's Twitter account just teased the inaugural glimpse of O'Brien as Mitch Rapp, the protagonist in Vince Flynn's fictional novels.

Yep, you do not want to f*ck with this guy (and damn, DOB looks good).

Now, a bit more background about the thespian's part. Rapp is a CIA black-ops recruit under the instruction of Cold War veteran Stan Hurley (Michael Keaton). From there, the duo is enlisted by CIA Deputy Director Irene Kennedy (Sanaa Lathan) to investigate what appears to be a series of random attacks on military and civilian targets. However, they discover a pattern in the violence that leads them to a joint mission with a lethal Turkish agent (Shiva Negar) to stop a mysterious operative (Taylor Kitsch) intent on starting a world war in the Middle East. THE SUSPENSE.

Be sure to check MTV News for any and all DOB updates, and don't forget Teen Wolf returns for the final installment on November 15 at 9/8c. And to refresh your memory for what's to come, catch the teaser clip below!
