Who is the toughest teenage mutant ninja turtle?


assistant
Whilst all the ninja turtles are training martial artists, who is actually the toughest is a subjective opinion. However, Raphael is normally portrayed as the most aggressive and toughest fighter due to his more aggressive demeanour and attitude. All are capable fighters, but Raphael is probably the one who would be the hardest to defeat.
