One idea could be the main character using gamer skills to quickly level up their Digimon in unexpected ways. For example, finding glitches in the Digimon world that allow for super - fast evolution. Another could be a tournament - style story where the gamer - like abilities of the protagonist give them an edge over other Digimon tamers.
A really cool plot idea could be that the gamer ability allows the character to hack into the Digimon code (in a non - malicious way within the fanfiction world). This enables them to customize their Digimon's appearance and abilities in ways not possible in the normal Digimon universe. They could then use these unique Digimon to take on challenges and save the Digimon world from a new threat that the regular Digimon tamers can't handle on their own.
One idea could be the Digimon characters getting lost in Wonderland. They might encounter the strange creatures of Wonderland and have to figure out how to get back to their own world. For example, Agumon could meet the Cheshire Cat and have a confusing conversation about directions.
One idea could be the main character using gamer skills to outwit opponents in Yu - Gi - Oh duels. For example, they might analyze the game like a strategy video game, quickly calculating the best moves based on the cards in hand and on the field.
Well, perhaps Naruto is turned into a character in a popular gamer's game. The gamer then has to guide Naruto through various levels that are based on different parts of the Naruto world, like the Chunin Exams or battles against the Akatsuki. Or, Naruto could be given a gamer - like ability, such as the power to save and load his life at certain points, which would completely change how he approaches battles and missions.
One idea could be that Danny somehow gets transported to the Digital World. He uses his ghost powers in unique ways to survive and help the Digimon. For example, his intangibility might be useful against certain digital threats that the Digimon can't deal with on their own.
One idea could be that the gamer's leveling system is applied to the Fairy Tail world. For example, the characters can gain XP by completing quests like in the game. They might level up their magic abilities in a more numerical way, similar to how a gamer levels up their character stats. Another plot could involve the gamer character introducing modern gaming concepts to the Fairy Tail guild, like mini - games for training or new ways to strategize during battles.
One idea could be that the protagonist from 'The Gamer' gets transported into the world of 'Familiar of Zero'. He could use his gaming skills to navigate the complex political and magical situations there. For example, he might level up in the magic system of 'Familiar of Zero' in ways that the natives find astonishing.
One idea could be that the main character from 'The Gamer' gains the power to level up in the 'Kingdom Hearts' world. So they start leveling up their keyblade skills like it's an RPG. They could also gain stats related to magic, speed, and strength, which would change how they interact with the Heartless and Nobodies.
One idea could be the main character using gamer skills to quickly learn Nen abilities in unique ways. For example, they might have a leveling system for their Nen types, which gives them an edge in battles against other Hunters or enemies.
An interesting concept could be an OC who is initially afraid of Digimon but is forced to team up with one. As they journey together, they gradually overcome their fear and develop a deep bond, learning important life lessons along the way.
Another interesting concept is that some of the Digimon end up in the Naruto universe and are mistaken for strange summons. Naruto befriends them and helps them find a way back home. In the process, he learns about their unique abilities and how they can be used in battles. For example, a Digimon like Gatomon could use her speed and claws in combat alongside Naruto.
