A craze that first started in Japan is becoming more and more popular here in London.

It is called 'Cosplay' and involves dressing up as your favourite superhero or science fiction character - and then meeting up with others, who do exactly the same thing.

BBC London's Charlotte Franks met Cosplay fan Rebecca Moriarty and Jessica Banks from London Animeleague.
