Their relationship could start with hostility. Masquerade is often a mysterious and somewhat menacing figure, and Alice might be suspicious of him. But as they interact more, especially in the context of Bakugan battles, they could gradually develop a grudging respect for each other's skills. For example, if they keep facing off against each other in battles and each time they learn something new about the other's strategies.
Maybe a plot where Alice and Masquerade are forced to team up. They could be in a situation where they have to battle a common enemy that is far more powerful than either of them alone. At first, they might be hesitant and full of mistrust, but as they fight together, they start to understand each other better and develop a strange sort of friendship. This could also involve exploring their different fighting styles and how they combine them to defeat the enemy.
One great Bakugan fanfic featuring Alice and Shun could be one where they team up for a special Bakugan battle tournament. They combine their unique strategies, with Shun's agility and Alice's intelligence, to outwit their opponents. Maybe in this fanfic, they also have to face some challenges outside of the battle, like dealing with a malfunctioning Bakugan gate that could disrupt the entire tournament.
A fanfic centered around Alice and Shun could explore their relationship. Maybe they start as rivals in the Bakugan battles but gradually realize they have a lot in common. For example, they both have a strong sense of justice and a love for their Bakugan partners. As they spend more time together, they could form an unbreakable bond.
There could be many scenarios in such a fanfic. Maybe they share a kiss after a great battle where they realize their deep feelings for each other. It could be a moment of celebration and the start of a new relationship in the Bakugan world.
There are quite a few fanfics out there. Some focus on the relationship between Alice and Shun in a more platonic way, like the fanfic 'Bakugan Allies'. It shows how they support each other during battles and in their daily Bakugan - related adventures. It's a great read if you like stories about friendship within the Bakugan universe.
They could be on a quest to find a rare Bakugan that has special powers. Shun's stealth and combat skills along with Alice's strategic thinking would make them a great team.
A plot that drives the story forward. This could be a search for a rare Bakugan, or trying to stop an evil force that is using Bakugan for bad purposes. And the dialogue. The way Lync and Alice communicate, whether it's arguing about battle tactics or sharing their feelings about the Bakugan world and their place in it.
One possibility is that they go on an adventure in the Bakugan world. They might encounter new Bakugan species and have to work together to overcome challenges. For example, they could find a powerful but dangerous Bakugan that has been causing chaos in a particular area. Lync's skills and Alice's intelligence would combine to figure out how to tame or defeat this Bakugan.
For Shun, he might become more open and less reserved. Usually, he is a bit of a lone wolf, but through his interactions with Alice in the fanfic, he could start to trust others more and work better in a team. He could learn new strategies from Alice and incorporate them into his Bakugan battles.
