Princess Bubblegum could be an interesting pairing as well. She is intelligent and resourceful. In a fanfiction, she could try to use her scientific knowledge to find a way to defeat or control the Lich, leading to a lot of tense and exciting situations.
Jake could also be a good choice. Jake's laid - back and fun - loving personality would be a great foil to the Lich's menacing presence. Maybe Jake could try to use his shape - shifting abilities to outwit the Lich in the fanfiction.
Finn would be a great character to pair with the Lich. Finn is the hero, so the contrast between his good - natured self and the Lich's evil would create a lot of interesting story possibilities. They could have some epic battles or, as I mentioned before, an unexpected alliance.
One great fanfiction is 'The Lich's Unseen Past'. It delves into the Lich's early days and gives a possible backstory that makes his actions in the show more understandable. It's a great read if you want to get a deeper sense of the character.
Finn and Jake are great choices. Finn's heroic nature and Jake's laid - back but powerful abilities can create interesting interactions with the Ice Princess. Another good one is Marceline. Her vampire nature and the Ice Princess' ice powers could lead to some cool battles or alliances. Princess Bubblegum could also be a good pairing as they are both princesses, and their different personalities, PB's scientific mind and the Ice Princess' more emotional nature, could make for a great story.
In many of these fanfictions, authors often play with the idea of redemption for The Lich. They might create scenarios where Finn or Jake try to reach out to the good that might still be buried deep within him. This can lead to some really thought - provoking stories that deviate from the typical 'The Lich is just pure evil' narrative we see in the show.
The Lumpy Space Princess could also be paired with the Ice King. Her sassy attitude could contrast with the Ice King's craziness. In a fanfiction, they could end up on an adventure together where the Lumpy Space Princess tries to 'fix' the Ice King or just uses him for her own gain in a really comical way.
Naruto and Finn are often paired. They are both the main protagonists in their respective shows and have a lot of similarities. They are brave, determined, and always looking for adventure. Their combined energy would make for an exciting story.
Well, if the lich was good, it would change the entire dynamic of the Adventure Time universe. Characters' relationships and plot developments would be very different. It could open up new possibilities for adventure and conflict resolution.
Definitely Marceline. Since she has a long - standing relationship with Simon (Ice King), her presence can add a lot of depth and emotion to the story. Their past connection gives a lot of room for interesting interactions.
Chat Noir would be a great pairing. Their different powers and personalities could create some really fun and exciting interactions. Chat Noir's flirty nature combined with Multimouse's more cautious approach would make for an interesting dynamic.
Goku is a great character to pair with Beerus. Their relationship in the original series is full of tension and mutual respect. In fanfiction, they could have all sorts of adventures together, like exploring new galaxies or training in unique ways.
Chloe could be a great addition. She could be a supportive friend who helps Clana in their relationship, or there could be some friendly jealousy triangle situations that add drama. Another good character to pair with them could be Lex. His complex relationship with both Clark and Lana in the original show can be further explored in fanfiction, like how he might try to break them up or use their relationship for his own gain.
