how many ninja turtles are there

There are four original Ninja Turtles : Leonardo, Donatello, Raphael, and Michelangelo, who are the most well-known characters in the Teenage Mutant Ninja Turtles (TMNT) franchise. However, beyond these original four, the wider TMNT universe actually includes up to 12 Ninja Turtles when considering newer characters and iterations from various comic series and adaptations. Notable additional Ninja Turtles include Venus de Milo, a female turtle introduced in a 1997 live-action TV series and later comics, as well as four brand-new turtles named Odyn, Yi, Moja, and Uno introduced in recent TMNT comic series. These expansions bring more characters into the Ninja Turtle roster beyond the classic four.
