A New York neighbourhood clubbed together to throw the cutest parade ever for four-year-old Ellie Evangelista, who was told by boys at school that she couldn't be Spider Man because she's a girl.
After hearing of Ellie's plight, parents from her neighbourhood organised the first-ever Uptown Superheroes March, where boys were free to be Wonder Woman and girls were free to be Spider Man.
Ellie's mother, Margaret Ryan said: "She started coming home and talking about not wanting to be a girl anymore because some boys at school were telling her she couldn't be Spider Man because she was a girl."
Ellie was so adamant that she would be her favourite superhero, that she created a pretend world in which she'd be a boy in the day at school, then revert back to being a girl in the evening.
Unsure of how to deal with her daughter's situation, Ellie's mother turned to other parents for advice. It was then that she realised that she wasn't alone.
"So many parents responded to it. Whether they had little girls going through the same thing or had heard their own little boys saying similar things to girls," she said.
From there, the idea of the Uptown Superheroes March was born, but the organisers never anticipated the huge response.
The Daily Beast reported that the march on Sunday was "more diverse than the Justice League".
One father of a six-year-old Superman named Lola said: "Whatever you want to be, you should be able to be. I think that's the world we're trying to get to and I hope that's the world my daughter lives in at this moment".
Ellie's mum added: "I hope that she can remember this experience and feel more comfortable with being who she is."
