These children got a special visit from some noble superheroes.

Patients and their families at the ProMedica Toledo Children’s Hospital in Ohio had a Halloween they will never forget, last week. On Oct. 30, members of the Toledo police SWAT team donned superhero costumes and arrived on the hospital roof via helicopter, according to ProMedica's YouTube page. The team then scaled down the building and surprised children at their windows, acting as heroes in a staged heist.

"It was awesome," police patrolman Matt Slaman, aka Wolverine, told ABC13 of the experience. " To see all the kids ... as you're going down the floor -- all those people in their rooms -- you can see their faces light up. So, you're really seeing you're bringing some joy in their life."

Appearances were made by Thor, Superman and the Hulk, among other famous heroes and comic book characters. The characters' grand introduction was viewed on a TV indoors, featuring a newscaster. The group's "mission" was to stop the sinister Dr. Trickster, whose plan was to ruin Halloween in Toledo. The good guys descended the building -- Spider-Man climbing upside-down -- and met their villain on the ground, defeating him once and for all.

The act ended with a pre-recorded video of Dr. Trickster being taken into custody by the SWAT team. The heroes proceeded to take pictures with their fans and their families, according to the Toledo Blade.

The SWAT team was inspired by different stories of window washers dressing up as superheroes and surprising sick kids, the outlet reported. Those involved said they had a blast bringing smiles to the faces of those inside. The children watching were pretty pleased with the heroes' crime-fighting as well.

"It was pretty cool," said Nicholas Pinkstaff, an 8-year-old at the hospital, told the Blade.

The heroes successfully spread the magic of Halloween to the children and their families this year, and, Slaman says, he hopes to come back to bring more cheer to the hospital for years to come, ABC13 reported.
