Monapril

Monapril is the femslash ship between Mona Lisa and April O'Neil from the Teenage Mutant Ninja Turtles fandom.

Raphael Meets His Match
April is covering the story of the party and is talking to Raphael, when a girl in a lizard costume comes over and steals him away. When April sees Raph again, she asks who the girl was. Raph says that he doesn't know, since she disappeared once they got onboard. April suggests she's playing hard to get, but Raph doesn't think so and goes to look for her.

After the party gets taken hostage, April finds Raph. She comments on finding his friend in the lizard costume, Mona Lisa. Mona then says that she's not in a costume, and that she's actually a mutant. She then explains how she became the way she is, and Raph comforts her after. April says she hates to spoil the moment but they do need to save the world.

Fanon
Monapril is a very rare pair in the TMNT fandom. While April had a few interaction with Mona in both 2012 and 1987, they weren't very significant. As a majority of Mona's screen time is always spent with Raphael, meaning that other relationships don't get to develop as well. While fans aren't necessarily disappointed that Mona and April didn't interact that much, they're more disappointed by the lack of positive female relationships. As TMNT is a franchise that doesn't have many. 2012 not allowing them to interact makes many fans feel like there was a missed opportunity with the two not interacting.

Although the relationship isn't all the explored for either version in many fan works. This is most likely due to Mona's lack of screentime, and the fact that many fans dislike 2012 April. Meaning that many fans don't make it a priority to explore their relationship in works. Although many fan artists will put them in the same group shots for female TMNT characters that they enjoy.

On AO3, there are currently 2 written works.
