Time to get your tissues! In the comic book Teenage Mutant Ninja Turtles #44, one of the Ninja Turtles is seemingly killed off.

Who? And how? Shredder's genetically mutated thugs Bebop and Rocksteady kill

Donatello

. Leonardo, Raphael and Michelangelo are off battling Krang, trying to stop him from terraforming Earth with his Technodrome. While that is going on Donatello is manning the home base. Shredder ordered Bebop and Rocksteady to take care of Donatello. Donnie and Metalhead do their best to fend them off, but Rocksteady and his mighty sledgehammer are too much.

The issue was written by Tom Waltz and TMNT co-creator Kevin Eastman.

This is comics afterall, but knowing one of the original Turtles might not make it is certainly a game changer. Stay tuned to ComicBook.com next month to see what happens next.
