Some TMNT stuff really isn't for little kids.

The Ninja Man-Bats, also known as Man-Bat Commandos, are a faction of the League of Assassins which use the Man-Bat Serum to mutate into anthropomorphic bat creatures. They were sent to attack Batman when he was heading towards the Lazarus Pit in Batman/Teenage Mutant Ninja Turtles II.

They reappear later in the story when Raphael and Robin place Splinter in the Lazarus Pit to heal him. They were subsequently defeated by Batgirl, Nightwing, Robin, Raphael and a newly-healed, more aggressive Splinter.
