Yes, characters regularly walk around and interact with guests at both Universal Studios Orlando and Universal Studios Hollywood. Unlike some other theme parks where characters are strictly confined to "meet-and-greet" stations, Universal often features "roaming" characters that add to the immersive atmosphere. In 2026, you might find Beetlejuice, Marilyn Monroe, or Doc Brown strolling down Hollywood Boulevard, or Frankenstein's Monster lurking near the Production Plaza. In Marvel Super Hero Island, heroes like Spider-Man and Captain America roam the streets, while villains like Dr. Doom might "menace" passersby. For specific fan-favorites, there are dedicated spots: The Simpsons family can be found outside the Kwik-E-Mart, and SpongeBob SquarePants hangs out near his pineapple home. The interactions are often more "free-form" and humorous, particularly with characters like Donkey from Shrek or The Grinch during the holidays. You should check the official Universal app for "scheduled" appearances, but part of the magic is the "random" encounter with a Minion or a Raptor as you walk through the parks.
