Pepsi, a brand of Purchase, N.Y.-based PepsiCo Inc., has confirmed that Pepsi Perfect, the fictional beverage that Marty McFly orders in “Back to the Future Part II,” will be available for a limited time starting Oct. 21 paying homage to the date that McFly travels to in the future.

"Pepsi fans asked and we heard them loud and clear," said Lou Arbetter, senior director of marketing for PepsiCo, in a statement. "The ‘Back to the Future’ trilogy was as big a moment in pop culture history then as it is now, 30 years later. We are excited to be part of this moment and to bring fans something only Pepsi could deliver — and there's no need to wait — the future is now."

Pepsi Perfect will be available for purchase online while supplies last. Only 6,500 Pepsi Perfect bottles, each outfitted in a special collectible case, will be available to U.S. consumers. The beverage will be packaged in a 16.9-ounce bottle and will contain Pepsi Made with Real Sugar. It will retail for $20.15, the company says.

However, “Back to the Future” fans who are attending New York Comic Con will get a chance to get a bottle of the beverage before it is made available online. Each day, the first 200 fans who come to the Pepsi Perfect Booth dressed as Marty McFly will take home a bottle of Pepsi Perfect. The McFly schedule will take place 1-2 p.m. Oct. 8 and 11 a.m.-noon Oct. 9-11.

The following attire must be worn to qualify as a McFly outfit: puffy red vest or “Back to the Future Part II”jacket; blue jeans; white high-top sneakers; watch; and, optionally, a hoverboard.

Every day starting at 3 p.m., fans also are invited to play Wild Gunman at the Pepsi Perfect booth for a chance to win Pepsi Perfect. Bottles will be awarded to the fastest gunman.

"New York Comic Con is the ultimate fan destination and the first place for exclusive entertainment experiences," said Lance Fensterman, senior global vice president for ReedPOP, producers of New York Comic Con, in a statement. "We're honored to join Pepsi Perfect in this special “Back to the Future”moment; we just hope that it doesn't upset the space-time continuum."
