With only nine episodes left, Fox's Batman origin series Gotham is nearing its endgame. For the past five years, the series has methodically showed the evolution of some of the biggest characters in the Batman mythology, taking them from their young days to what they will ultimately be in the comic books.

Bruce Wayne is moving ever closer to becoming the Dark Knight, Selina Kyle has just become Catwoman and the series' lead villain, Oswald Cobblepot, aka the Penguin, is about to truly become the comic book character we know and love.

Ever since his first appearance in the pilot, Robin Lord Taylor's Cobblepot has had the stylish look of the Penguin, but his slimmer and taller appearance made his take on the character a departure from the classic Batman villain fans are familiar with. However, that won't last. Before the series is done, Cobblepot will truly look like the comic version of the character.

On The Wendy Williams Show, actor Robin Lord Taylor revealed Oswald will go through a physical transformation on Gotham. "We jump forward at the end of the season, so we'll actually get a glimpse of the Penguin that we all grew up with," the star revealed.

When asked if he had to wear a fat suit later in the season, Taylor answered, "Yes, yes I do." However, Cobblepot won't just grow in size -- it appears he will also change into more of a monster. "You know it's interesting, because I was talking to our costume designer John Glaser," Taylor continued, "I was saying I don't want him to be like a cartoon. I was thinking like the Blueberry Girl from Willy Wonka -- I didn't want that kind of look. So we went with something a little more monstrous. There's a hunch on his back. He's becoming a monster this season."

We've known for a little while now that Gotham's final episode would jump forward in the future and that the Penguin would don a comics-accurate costume, but it will be interesting to find out what will lead to Penguin's physical transformation.

Airing Thursdays at 8 p.m. ET/PT on Fox, Gotham stars Ben McKenzie as James Gordon, Donal Logue as Harvey Bullock, David Mazouz as Bruce Wayne, Robin Lord Taylor as Penguin, Camren Bicondova as Selina Kyle, Erin Richards as Barbara Kean and Sean Pertwee as Alfred Pennyworth.
