Harley Quinn has always been a cosplay fave—especially after Margot Robbie brought her to the big screen in Suicide Squad.

But Harley has one little fan who absolutely owned the look at Comic-Con, and that’s Liev Schreiber’s son Samuel Kai.

Schreiber was at Comic-Con over the weekend to promote My Little Pony: The Movieso he brought along his cosplay-loving sons Alexander “Sasha” Pete and Samuel Kai. Judging by Schreiber’s Instagram, it seems like the kids go by Sasha and Kai.

Kai is a perfect Harley Quinn and Sasha looks like he’s wearing a Black Panther mask with a Star Wars-inspired robe. Nice.

Schreiber told Entertainment Tonight that his kids were obsessed with Comic-Con, because who wouldn’t be? “So far we’ve already had three battles with Stormtroopers, we’ve met a bunch of guys dancing around in kilts, we did VR [virtual reality] down in the Alien: Covenant room,” he said.

We love that Schreiber gives his son the freedom to express himself in a non-gendered way. If Harley Quinn is your queen, then express yourself!

At Halloween this year, Kai went as a bloody bride, because who says little boys have to dress up as zombies and pirates and little girls have to be princesses and brides?

Schreiber and Naomi Watts announced their separation to People in September 2016, but it seems like they have a knack for this co-parenting thing. Here they are in January 2016—before their split.

All in all, we think this trip to Comic-Con solidifies Schreiber as the coolest dad ever.
