A good 'Ash catches Latias' fanfiction should have a well - developed relationship between Ash and Latias. Their interactions should feel natural and not forced. For example, if Ash saves Latias from danger, the way Latias responds and the development of their bond should be believable.
One possible plot is that Latias is injured and Ash finds it. He nurses it back to health, and during this process, they form a bond. Latias then decides to join Ash's team. Another plot could be that there is a tournament where the prize is a special item that can attract Latias. Ash enters the tournament, wins, and uses the item to catch Latias.
His confidence could grow in a different way. Usually, Ash is confident in battles, but this time, when he catches these rare Pokémon, he might gain confidence in his ability to understand and bond with Pokémon that are very different from the ones he's used to. He could start to see himself as a more well - rounded Pokémon trainer, not just one who battles but also one who can form deep connections with all kinds of Pokémon.
One possible plotline could be that Ash stumbles upon Latias while exploring a new region. Latias is initially shy but Ash's kind nature draws her in. They start to form a bond as Ash helps Latias when she gets injured by some wild Pokémon. Another could be that Latias is being chased by a group of poachers and Ash steps in to protect her. This leads to an adventure where they have to outwit the poachers and in the process, Latias decides to stay with Ash for a while.
In such a fanfic, Ash might catch Latias using his usual determination and battle skills. Maybe he first encounters Latias when it's in trouble, like being chased by some bad guys or trapped in a dangerous situation. He would then use his Pokémon team to protect it and gain its trust over time. Eventually, with a well - executed Pokéball throw, he catches Latias.
Ash could catch Latias in a place full of ancient ruins. Latias might be guarding some sort of Pokemon relic there. Ash shows respect for the place and Latias' role. This makes Latias interested in him. Eventually, Ash catches Latias and they go on to discover more about the relic's power together.
One possible plot twist could be that Latios and Latias are actually under the control of a more powerful and evil Pokémon. Ash initially thinks he's caught them to protect them, but then discovers he has to fight against the real threat that has been manipulating them all along.
Well, in Ash and Latias romance fanfiction, it often explores a very unique relationship. Ash is a well - known character, and Latias being a Pokémon, their relationship in such fanfictions usually defies the normal boundaries of human - Pokémon interaction in the official series. It can be really interesting to see how authors develop their emotional connection, like how they might communicate on a deeper level despite their differences.
One possibility could be that in the fanfiction, Ash betrays Latias out of a misunderstanding. Maybe he was tricked by a villain into believing that Latias was a threat to the region. This would create a lot of drama and conflict in the story as Latias, who probably trusted Ash, would be deeply hurt.
