Jakub Wrona, seven, from Leeds, was taken down to London for a special carnival day, organised by a partnership between the London Designer Outlet Centre and Rays of Sunshine, a charity which grants wishes to children with serious or life-limiting illnesses.
Pulling up in a Lamborghini Batmobile, the crime-busting superhero duo chatted with Jakub and posed for photos alongside the brave primary schooler, in front of a crowd of local residents who turned out to cheer them on.
But the meet 'n' greet was interrupted in shocking style - for, unbeknownst to Jakub, Rays of Sunshine had arranged for The Penguin and Venom (two of the greatest comic book villains, for the uninitiated) to swoop in and attempt to spoil the happy event by stealing the key to the carnival.
Batman and Spiderman sprang into action, and, after a thrilling car chase, they had the nefarious pair cornered.
After the villains were escorted away - with a little help from local bobbies - the key was returned and Jakub was joined by the Lord Mayor of Brent, who declared the carnival day officially open.
Jane Sharpe, the charity's CEO, praised the community for lending their support to the event: "This was an incredibly special wish for Jakub. The entire community of Brent and Wembley came together to make sure it was as spectacular as it could have been.
"This year we hope to grant 800 wishes for seriously ill children, like Jakub, and we work hard to make sure each and every one is as special and unique as the child themselves."
