MARVEL'S superheroes have jumped in to help a seriously ill little boy.
Six-year-old Aaron Hunter suffers from Rohhad, a rare and uncurable disease that means he is always hungry and has difficulty breathing.
His parents have set up a charity to raise awareness of his condition and started an ice bucket-style challenge.
Called Go Mad Jump For Rohhad, it asks people to splash about in a puddle and donate to the charity.
First Minister Nicola Sturgeon has already put on her wellies and given it a shot.
Avengers-daft Aaron challenged his favourite Marvel superheroes to give it a go.
And after months of waiting, four cast members from the live show have taken him up on it.
His face lights up as he sees four of the American cast members greet him by name then leap about in the water.
And he can't wait to thank them all in person when Marvel Universe Live comes to Glasgow in January .
Aaron's mum Elisabeth said: “Aaron is so happy and very excited about seeing the show and meeting the characters. He is so grateful to them for doing this for him and the other Rohhad children.”
Marvel Universe Live has also donated 10 family VIP tickets for the Hydro show. The charity will raffle them to raise funds.
They also sent Aaron a goodie back of superhero merchandise to keep him going until January.
