In this fanfiction, the story could start with Laxus finding the pet tiger in a strange situation, like it being held captive by an evil wizard. Laxus rescues it and they form an immediate connection. As time passes, the tiger grows into a magnificent and powerful beast. Laxus has to deal with the fact that some people in his community are afraid of the tiger. He then has to prove that his pet is not a threat but a valuable ally. He might take the tiger on quests to show its loyalty and usefulness, and along the way they encounter various obstacles and make new friends who come to accept the tiger as part of their group.
One possible plot could be that they accidentally end up having to take care of a baby during a mission. Maybe they find an orphaned baby in a dangerous situation and decide to protect it. This could lead to some really cute and funny moments as they struggle to take care of the baby's needs while also dealing with the threats around them.
The tiger could be very protective. Since Laxus is its owner, it would be fiercely loyal and would not hesitate to defend him against any threat. It might be a bit wild at heart still, with a playful side that comes out when it's just with Laxus in a safe environment.
The story might start with Naruto finding the tiger cub in the forest. He decides to take it in and raise it. As the tiger grows, it becomes his loyal companion. They train together, and the tiger learns some ninja - like skills. For example, it can pounce on opponents like a ninja would attack. It could also be a source of comfort for Naruto when he's feeling down, like how a normal pet would be for its owner.
Well, perhaps Laxus has some misguided notion that Lucy has information vital to the guild's safety. So he kidnaps her thinking he can extract it from her quickly. But in reality, Lucy has no such information and she has to convince Laxus of that.
The plot might revolve around Naruto growing up in a different world or with a different family dynamic due to being the son of Laxus.

He might struggle to fit in at first but then use his unique combination of abilities to become a great hero in both realms.
Well, perhaps the story could start with a powerful magic spell gone wrong that turns Laxus into a baby. His friends might be shocked at first.

Maybe the story could revolve around how their guild mates react to the news. Some might be overly excited and start planning big parties, while others could be more cautious and offer practical help, like setting up nurseries for them. It would show the strong community within the guild.
One possible plot twist could be that an old enemy resurfaces on their wedding day, threatening to disrupt the ceremony. Maybe a dark guild that Laxus once fought against comes back for revenge. Another twist could be that Lucy discovers a hidden family secret that might change her relationship with Laxus. For example, her family has some sort of connection to Laxus' past that she was unaware of. And a third plot twist could be that a magic spell goes wrong during the wedding, causing everyone to swap personalities for a while, which would lead to some really interesting and comical situations.
Perhaps she decides to go on a solo adventure to find out more about her family's past.
