Super fans dress up as Osaka for Halloween

Naomi Osaka dressed up this Halloween as Numbuh 5 from "Codenames: Kids Next Door". While her costume was solid, it was all the other Naomi Osaka's out there that caught her, and everyone's, attention.

This year, adults and children dressed up as the 2020 US Open champion, inspired by her assent to outspoken superstar.

One family really went all out on the Osaka theme, complete with a son as a US Open trophy and a newborn as a tennis ball.

While another family embraced a group of athletes for social justice.

Osaka's inspiration wasn't just for children.

You know you've hit legend status when people of all ages are dressing up as you. Osaka finished her 2020 season ranked No. 3 after picking up her third career Grand Slam title in New York.
