SJ’s very own pint-sized superhero Iron Max is making a special appearance on NBC Nightly News with Lester Holt tonight!

For those unfamiliar with Iron Max, he’s the 6-year-old grandson of SJ Mag columnist Maury Z. Levy. Max was diagnosed with the blood disorder hemophilia A as a baby, and when he had a port placed in his chest (just like Iron Man!) the nickname Iron Max was born. Max was even drawn into a Marvel Iron Man comic, fighting bad guys alongside his hero.

Max’s sister Zoe, 9, had a big idea last year. She enlisted some friends to take photos and created Hearts4Hemophilia calendars to sell. The profits – more than $7,000 – went to support hemophilia research at Children’s Hospital of Philadelphia, where Max has been a patient.

The project was so successful they decided to do it again this year. Max, Zoe and 25 other friends took more than 100 photos for their new 16-month scholastic calendar. This year’s theme is “What Makes a Hero.” Calendars are available for a minimum donation of $20, and all proceeds go straight to CHOP.

Tune in to NBC at 6:30 pm tonight to watch Iron Max and friends tell the story of Hearts4Hemophilia.
