Brother dresses up as a turtle

When a kingpin threatens New York City, a group of mutated turtle warriors must emerge from the shadows to protect their home.

After years of being sheltered from the human world, the Turtle brothers set out to win the hearts of New Yorkers and be accepted as normal teenagers through heroic acts. Their new friend April O'Neil helps them take on a mysterious crime syndicate, but they soon get in over their heads when an army of mutants is unleashed upon them.

Everyone's favorite teenage mutants are back in live action to fight crime with help from a new ninja turtle -- a female named Venus De Milo.

The most radical superheroes on the planet are now full-grown Ninjas, and in this live-action adventure, "East Meets West," they discover a new enemy, the nefarious Dragon Lord -- and a new friend, Venus de Milo, a female Mutant Turtle. Together, the Turtles must outsmart and defeat the Dragon Lord and his warriors before they carry out their evil plans to achieve total invincibility and conquer the universe!

Turtles Forever is a made-for-tv animated movie. Produced in celebration of the 25th anniversary of the Teenage Mutant Ninja Turtles franchise, the movie teams up different incarnations of the titular heroes—chiefly the light-hearted, child-friendly characters from the 1987 animated series and the darker cast of the 4Kids' own 2003 animated series—in an adventure that spans multiple universes.

Batman, Batgirl, and Robin forge an alliance with the Teenage Mutant Ninja Turtles to fight against the Turtles' sworn enemy, The Shredder, who has apparently teamed up with Ra's Al Ghul and The League of Assassins.
