There’s something about secrecy and superheroes — even when it’s a local father and son caped crusader duo and their photo has gone viral after a recent Reddit posting.

They don’t want to be identified. Not only would it interfere with ongoing caped crusading, but it would hurt the privacy of the superheroes’ respective wife and mom and the baby sister in the family. The latter also is occasionally seen draped with her own wee cape, courtesy of her 3-year-old big brother.

Tiny capes, made from washcloths, have even been known to appear on shampoo bottles in the family bathtub, courtesy of the smallest superhero in the Toronto family whose name starts with an “F,” as emblazoned on the back of his cape.

Her son “adores superheroes and capes’’ and puts capes “on everything,’’ says his mom, an amateur photographer who took the photo of him and his dad at a local hardware store, while walking behind, holding the baby.

She thought the photo was cute and posted it on Reddit.

“I was just looking to provide a few people with a laugh. Then we went tobogganing and to a friend’s house for dinner. When I came home I checked my computer and saw that there were thousands of hits and comments.’’

A number of media outlets have also reported on the photo and its popularity.

Because her son likes to play superhero with his pals, as well as his dad, his mom also made a slew of small capes for friends, with their initials sewn on back.

Since the baby was born last October and has kept mom busy, father and son have been spending a lot of time together. After his mom made him a cape for his third birthday, “F’’ asked where his dad’s cape was. So his mom whipped up an adult-sized one, which is worn at home and sometimes on outside excursions, like the one to the hardware store.

Father and son also wear matching Star Wars shirts and superhero underwear.

The superhero’s mom is happy about the photo “going viral because it seems to have provided so many people with a smile.’’

She’s decided to donate the now-famous photo to SickKids hospital to be used for charity purposes or wall decoration. In addition, friends and family are making and donating items for SickKids for use in child patient dress-up, including tutus, knitted black batman masks, crowns, and a “superhero’’ quilt from Twice By Lightning. Mastermind Toys is donating some capes.
