Fans are introduced to the gender-flipped versions of Finn and Jake in the sequel series Adventure Time: Fionna and Cake, voiced by Madeleine Martin for Fionna and Roz Ryan for Cake. Because of their distinctive interpretation of the original duo, these characters have won many fans.

Fans believe that Fionna is between the ages of 20 and 30, considering her actual age isn't mentioned in the series (Adventure Time Wiki lists it as 30). Cake and Fionna and their experiences in the real world give these popular characters a new, distinct personality that sets them apart from the original duo of Adventure Time.

Simon Petrikov (former Ice King)

Simon Petrikov, the former Ice King (voiced by Tom Kenny), has one of the most captivating character journeys in the sequel series. Simon, who debuted in the first season of Adventure Time as a 37-year-old, is now 59 in Adventure Time: Fionna and Cake, clearly older and sporting gray hair and wrinkles. He was once shown as the silly Ice King, but today he is a gloomy and introspective figure.

In the spin-off, it is revealed that Simon works and lives in a tiny, one-room cottage inside an outdoor museum, where guests may see his exhibit. His unintended role in introducing Fionna and Cake to his world, as well as his desire to bring back magic to their world while being pursued by the mysterious God Auditor Scarab, give his character and the broader plot more complexity.

Finn, Marceline, and Princess Bubblegum

In Adventure Time: Fionna and Cake, fans of the original series are reintroduced to their favorite characters after 12 years. Princess Bubblegum (voiced by Hynden Walch), who is now in her late to mid-800s, makes a triumphant return, exhibiting her youthful brilliance.

The charming former protagonist, Finn (voiced by Jeremy Shada), has grown up and is now 29 years old. He is far more mature as a character as a result of his natural aging and continues to be a hero in Ooo.

Still In her early 1000s, Marceline (voiced by Olivia Olson is shown calling her adoptive father Simon. The fact that Marceline and PB are still dating and were seen getting tattoos together in Adventure Time: Fionna and Cake is a nice finishing touch.

Marshal Lee and Gary Prince

These two (also gender-bent) characters assume new responsibilities in Fionna and Cake's universe. Marshal Lee (voiced by Donald Glover), who is now in his mid-to-late-20s, goes through a transition in accordance with the magic-less reality of Fionna and Cake. He contributes his musical skills and unique personality to the follow-up. He is seen being captivated by Gary Prince's cookies, which prompted him to ask him out later.

Formerly known as Prince Gumball, Gary Prince (voiced by Andrew Rannells) is older than Fionna and works as a barista and pastry chef in Beatrice Buttler's bakery. Unfortunately, Gary despises his sweet creations. Love permeates the episodes he and Marshall appear in; thus, their transformations and interactions add to the sequel's distinctive plot.

Prismo, the Lich, and Scarab

Prismo (voiced by Sean Rohani), The Lich (voiced by Ron Perlman), and Scarab (voiced by Kayleigh McKee) are cosmic beings that have major roles in Fionna & Cake. Although his precise age is not stated, Prismo, a Wishmaster and embodiment of an old man's wish, is a figure with a natural age of over 1000 years. He has created the gender-flipped universe of Fionna and Cake and, according to the sequel, is now miserable.

Due to entering the portal to all universes, the Lich, an entity that symbolizes the unavoidable death of everything, exists in all dimensions. In the episode titled Jerry in Adventure Time: Fionna and Cake, the Lich makes an appearance as a depressed being due to him having his wish fulfilled. Like Prismo, he is naturally over a thousand years old.

Scarab is a cosmic auditor who checks on other cosmic entities to make sure they are operating within the rules. He claims that Fionna and Cake's very existence is a transgression and intends to destroy their universe, which was situated in Simon Petrikov's head, and he has been pursuing the group through the Multiverse to do it. He, too, is over 1000 years old.
