This is all part of a Make-A-Wish foundation project, which will see 5-year old Miles become Batman for the day, as per his wish, in order to save the day for the people of Gotham. Not only will Miles be officially deemed a Batman-in-training, and spend the day with the actual Batman himself, but he’ll also be saving the city from villains including The Puzzler and The Penguin.
After a full day spent chasing crime and protecting the city, he’ll be heading off to City Hall, where he’ll be thanked for his efforts by the Mayor and Police Chief for San Francisco. He’ll be handed the key to the city at a ceremony, making him the MOST successful Batman of all time.
If you’re in San Francisco, you can find more details at Miles’ Make-A-Wish page.
You can also help out, of course, by donating to Make-A-Wish here.
