Robert Downey Jr.'s daughter is mostly definitely Team Iron Man.

The 51-year-old actor, who dons Tony Stark's super suit once again in Captain America: Civil War, stopped by Jimmy Kimmel Live! on Wednesday and shared a photo of his 1-year-old, Avri, wearing Iron Man's armor hand.

"Clearly, she's made a choice. I said, 'Here's a shield and here's a gauntlet. It's up to you, '" Downey Jr. explained. "She just naturally gravitated toward this."

The 51-year-old actor also talked all things Spidey, revealing that the web-slinging superhero was his "whole deal" growing up and gushing over the Marvel Cinematic Universe's new friendly neighborhood Spider-Man, Tom Holland.

"He's a British actor. You've seen him in other stuff before, but he's fantastic," Downey Jr. raved of his 19-year-old co-star. "I like this Tom Holland guy."

RDJ also confirmed that Marisa Tomei is in fact playing Peter Parker's Aunt May, and let spill that she makes a cameo in Civil War. "She seemed ancient before," Downey Jr. joked of past Aunt Mays. "Now she's Marissa Tomei. He's got a hot aunt."

So, will the next time we see Iron Man be in the upcoming Spider-Man: Homecoming? "Perhaps I will," Downey Jr. said coyly. "We don't have a contract yet."

ET caught up with RDJ and his wife, Susan, at the premiere of Civil War, where he revealed his secret dad superpower. Find out what it is in the video below!
