Choi's name was spotted in the S.T.A.R. Labs scene.

An Easter Egg has been spotted in Justice League that reveals Ryan Choi aka Atom.

Justice League is arguably the biggest film to hit theatres this month. With DC Comic heroes Batman, Superman, Wonder Woman and Aquaman all joining forces, Justice League is certainly a must-see for any comic book fan.

Early on in the film, Silas Stone is seen at S.T.A.R. Labs trying to bring his son Victor back to life. Whilst the majority of the audience would have focused on the action inside the lab, eagle-eyed Reddit user naelps noticed a rather sneaky Easter Egg.

On the screen of one of the computers in the lab is a list of S.T.A.R. Labs employees, with Silas Stone’s name in red. Four names below it is the name Ryan Choi – a DC Comic character who becomes Atom.

Choi is an Asian-American physics professor who has the ability to shrink himself to subatomic levels. He is the fourth character to become the Atom.

It’s unclear whether Choi will make an appearance in the next Justice League film but the Easter Egg might suggest audiences could see the character in the future.
