For many children, meeting a superhero is a wish come true.

And for Ricky Mena, making it happen

has turned into a mission because

of a dream involving his late grandmother and Spiderman.

She came to me in a dream and basically showed me

a movie where Spiderman was handing out presents

to thousands of kids.

And she said that was what I was supposed to do when I woke up.

And I had the courage to wake up and actually follow that dream,

and it's turned into what it is now.

CALEB KINCHLOW: And that's Heart of a Hero,

a nonprofit organization designed

to inspire, motivate, and empower children who need it

most.

Are you supposed to be here much longer?

No?

That's good news.

You guys are going home soon?

RICKY MENA: Cancer is one of the big evil villains

that these kids battle, you know.

And it's just been incredible to know that they're battling

this thing four or five years.

They're in the hospital for the majority of their time.

They don't go to school, don't get to play on the playground,

lose all their friends.

And all they have is their mom or dad who have to work, too.

So you know, it's a pretty special thing

that we bring to the table.

CALEB KINCHLOW: In less than three years,

this Spiderman and his team has seen

more than 5,000 children battling life

threatening illnesses.

Ricky still remembers one of the first,

a 9-year-old who died from brain cancer named Charlie de Grange.

RICKY MENA: Going into that visit,

I knew that he was terminal.

He was 8 years old at that time.

His reaction was priceless, because he was just in shock

that Spiderman would come to him.

He was the first terminal child that I met.

And unfortunately, he was the first to pass away also.

I visited him as much as I could as Spiderman,

because we became really good friends.

And then I wrote a song for him, and it went viral on Facebook.

LYRICS: I'd trade your health for mine just

to sit and watch you play.

He saw the song-- cried.

And his father hit me up and said, you know what?

Charlie wants to meet the guy who wrote the song.

So I got a chance to be friends with Charlie twice.

His reaction every time I showed up whether it be Spiderman

or as myself was truly like priceless.

CALEB KINCHLOW: Heart of a Hero continues to expand,

seeking donations and partnerships

to support the mission.

RICKY MENA: It doesn't have to be Spiderman related.

We meet a lot of little girls who love Frozen.

We meet some kids who love Iron Man.

Anything that, you know, that kids like.

Do you like that backpack?

Yeah?

Well, guess what?

It's yours.

I brought it for you.

RICKY MENA: And that's a huge help to us.

We don't have to spend the money that we use on

travel and getting to know these kids on toys.

And it's truly a big help.

I can't meet every child across the United States.

So if I can find some good hearted people who

have a great character and have the heart to do it out there,

then that's what I want to do in the future.

Wait, one more.

Hold on.

All right.

I think I blinked on that on, so let's--
