Main Characters
Finn Campbell
Finnegan Campbell
The main protagonist, a version of Finn who ended up on Ooo years later than in canon. Regardless, with his instinctual fighting spirit and his need to help others he still ends up becoming Ooo's new greatest hero.- Adaptational Badass: He gets to grow into the same adventuring badass as his canon self but also has ice ninja powers that let him fight even better against threats.
- Adaptational Expansion: His ice ninja powers become a part of his regular moveset, while in canon he never used them after the episode he learned them in.
- Adaptational Nice Guy: Because he arrived at Ooo when he's already an adult and has had a stable upbringing he's much more considerate and calmer than in canon, which results in him avoiding various problems his canon self had with his persona relationships.
- Chick Magnet: Every girl on Founders Island has a crush on him, most notably Sarah, and on Ooo he becomes every princess' desired date, he also manages to catch the eye of Marceline and Huntress Wizard.
- Disney Death: Gets skewered by Flint and almost dies, in fact he's pretty much dead for a while until he manages to heal back thanks to the Candy Kingdom's efforts and some cosmic interference from Prismo and the Cosmic Owl.
- The Heart: Having been raised as a Helper by his mother means that he is often acting as the moral balance of his group of friends and even helped make peace between the Candy and Flame Kingdoms.
- Heroes Prefer Swords: Like in canon his weapon of choice is a sword, though in this story he inherits Nothung from the deceased Billy.
- I Choose to Stay: Eventually chooses to stay in Ooo, having come to see that his life in the chaotic place is preferable to living a dull and unfulfilling life like he would've in Founders Island. He tries to communicate this to his mother but it winds up making things more complicated.
- Your Approval Fills Me with Shame: He doesn't say it outright but it's clear that he's disturbed and made twice as remorseful when the Lich remarks on his killing of Dr. Gross who he viewed as family and that he's actually proud of Finn for it.

Jake the Dog
Finn's best friend and his "bro", while they're not brothers here they still share a close bond with each other.- Adaptational Jerkass: In the past when Bubblegum got Jake to help her against the Lich he decided to take snack breaks despite the gravity of the situation which caused him to become infamous for his apathy.

Here since Finn meets her at an older age she does develop feelings for him, which cause tensions when Finn begins dating Marceline.
- The Chains of Commanding: The effects of the stress of leading a country have taken their toll on her, especially with the added guilt of the unintentional fallout of her actions which among them included Billy's death when she brought him out of retirement to fight the Lich.
- Jerkass to One: While she gets along swimmingly with mostly everyone she starts out cold towards Marceline and outright disdainful of Ice King; the former being due to the two breaking up in the past and the latter for constantly kidnapping her even after his turn to good.

- Not-So-Well-Intentioned Extremist: She acts like she just wants to help humanity prosper by any means even if it's through depriving the people of Ooo of their lands and massacring them, but it soon becomes clear she's an egomaniac with a superiority complex, furthered when it's revealed she arranged for Finn ending in Ooo to begin with.
- The Right of a Superior Species: She views her genocidal ambitions as this, since she believes humans are superior to the "mutant freaks" of Ooo and thus deserve to take back the place that once was their home by any means.
