There were plenty of stellar looks at San Diego Comic-Con, but one costume stood out from the pack: Liev Schreiber's 8-year-old son, Kai, came dolled up as Suicide Squad vixen Harley Quinn.

The Tony-winning actor was promoting the forthcoming My Little Pony movie, and brought his two sons—older brother Sasha rocked a mashup Star Wars/Black Panther costume, but Kai went as the Joker's main squeeze.

On social media, fans praised Schreiber for not freaking out about silly gender norms.
