Is it a bird? Is it a plane? No, it’s the Kardashians!

Kourtney Kardashian and her three children -- Mason, 5, Penelope, 3, and Reign, 10 months -- got into the Halloween spirit a little early when they donned superhero costumes on Saturday.

PHOTOS: North West and Her BFF Were Super Adorable at a Pumpkin Patch

The 36-year-old reality star shared an adorable photo of her little crime fighting “squad” on Instagram. Even her niece -- Kim Kardashian’s 2-year-old daughter, North West -- got in on the portrait, although she was dressed up as a unicorn.

In another Instagram snap with just her kids, Kourtney showed off her killer body in the one-piece gold Superwoman costume while holding Reign. Mason can be seen standing in front of his mom unleashing his superhero moves, while Penelope keeps it casual, just letting us admire her too cute mask, cape and tulle skirt.

The Keeping Up With the Kardashians star may not be a superhero in real life, but she does seem to be a super mom.

Despite her split from longtime boyfriend and father to her children, Scott Disick, in July, she has managed to keep the focus on both her family. She flew out to Las Vegas to be by her sister’s side when Khloe Kardashian’s husband, Lamar Odom, and she’s shared many pics of her adorable kids over the last few months, including a snap from a short vacation in Yellowstone National Park with Reign and a few friends last month.

And that killer bod? It comes courtesy of working very hard at the gym. “Working out is one of the only things that helps when I’m feeling anxious,” she admitted on Instagram last week.
