According to BoundingIntoComics:
While most fans’ attentions were understandably more focused on producer Seth Rogen’s decision to subject April O’Neil to her second such race-swap in Teenage Mutant Ninja Turtles: Mutant Mayhem, it seems two more members of the Turtles’ cast have likewise received a ‘modern update’.
These changes revealed in a series of promotional images released alongside the trailer – which did announce the actors’ participation but did not specify their roles – it appears that Wingnut and Leatherhead will have their genders-swapped in their silver screen debuts.
Per said images, the franchise’s resident Batman parody will be portrayed by actress Natasia Demetriou, one of the stars of the television version of What We Do In The Shadows.
While the fan-favorite crocodile mutant will be brought to life by Peter Rabbit and X-Men: First Class star Rose Byrne.
As noted above, these casting decisions – under the presumption that, like both this film and Across the Spider-Verse, respective characters must share their superficial traits with their voice actors – will result in the two characters being presented as women rather than their originally intended male forms.
First briefly introduced in the Peter Laird-produced comic series included with American food producer Ralston Purina’s 1989 cereal, Wingnut makes his first proper appearance in the 123nd episode of the 1987 animated series, Zach and the Alien Invaders.
