There have been many actors over the years who have adopted that raspy voice, worn the black Batsuit, driven the Batmobile and saved Gotham from impending doom.
But Michael Keaton is here to tell you, he's the one true Batman.
The 66-year-old actor was speaking at a Kent State University graduation where he regaled the students with tales of his time on the campus. He told them to respect each other, strive for greatness and be the change that they want to see in the world.
But just before he was about to hop down from the lectern, he said: "I've got one more thing to say and it'll only take me a second. I've got two words that I want you all to remember, they're very important and if I leave you with anything, I'm going to leave you with these two words.
"And those two words are: I'm Batman."
The crowd, understandably, went wild.
The laughter, applause and cheers probably came from the parents and faculty in the crowd as most of the students might be scratching their heads as to when the actor was the Bat.
Keaton became Bruce Wayne/Batman in 1989 in Warner Bros blockbuster directed by Tim Burton, starring alongside Jack Nicholson as the Joker, Billy Dee Williams as Harvey Dent, Michael Gough as Alfred the butler and Kim Basinger as the love interest.
There's no denying that the film was a Box Office smash, pulling in a casual $411 million worldwide after being made for a measly $35 million.
The Academy Award nominee reprised his famous role three years later in Batman Returns, which included Danny DeVito as The Penguin, Michelle Pfeiffer as Catwoman and Christopher Walken as Max Shreck - however it made nearly half the money at the Box Office as the original and the cost to make was more than double.
Others to become Batman on the big screen over the years include Adam West, Val Kilmer, George Clooney, Christian Bale and Ben Affleck.
Keaton's speech was very similar to that scene at the end of Iron Man, where Tony Stark (Robert Downey Jr) is facing a bunch of journalists demanding to know who the hell this flying superhero was wreaking havoc all over the world.
Instead of reading from a carefully prepared speech, Stark simply looks at everyone and says: "I am Iron Man." Much to the dismay of Pepper Potts (Gwyneth Paltrow).
