It could be because the author gave him that skill to add an exciting element to the story.
Lance being able to shoot a gun in the fanfiction could be a result of a training arc or a unique situation that required him to acquire this skill. It might also be a way to make him stand out or contribute differently to the story's action scenes.
Maybe it's part of Lance's character development or to face a specific challenge in the fanfiction. The author might have wanted to showcase his hidden talents or give him a new ability for plot progression.
There could be an outside influence like an alien force that is manipulating Shiro's actions. This force might be trying to break the team apart by making Shiro harm Lance. It could also be that Shiro has been infected with some sort of virus or energy that affects his judgment and behavior, causing him to hurt Lance without his true self intending to do so.
A lot of the fanfictions about their kiss also explore the reactions of the other characters in the Voltron team. Some might be supportive, while others could be initially shocked or confused. The kiss can also be a symbol of a new era in the team's dynamics, as Keith and Lance's relationship changes. It can lead to interesting storylines about how the team adapts to this new development.
Lance speaking Spanish in Voltron fanfiction is really cool. It can help in character development. It gives him an extra layer of personality. Maybe he uses it when he's feeling homesick or when he wants to show off a bit. Writers often use it to make him stand out more among the other characters.
One common theme is the overcoming of internal barriers. Both Keith and Lance have their own insecurities and issues that they need to deal with before getting to the point of a kiss. Another theme is the exploration of their different personalities coming together. Keith's more brooding nature and Lance's more outgoing personality can create interesting dynamics in the lead - up to the kiss.
It makes Lance more distinct. Spanish phrases can convey his emotions in a different way compared to plain English in the fanfic.
I'm not aware of any such fanfic, and creating or promoting fanfic with inappropriate and unethical content like this is not acceptable. Fanfic should be based on positive, creative and ethical ideas within the framework of the original work.
He might be polite but a bit guarded at first.
In such a fanfiction, the team would probably be in chaos at first. They'd have to figure out how to take care of a baby Lance. Keith might be really confused but also feel a sense of protectiveness. Pidge would be curious about how this happened scientifically. Hunk would be the most nurturing, making sure baby Lance is fed and comfortable.
In this fanfiction, Keith might initially feel out of place when meeting Lance's family. He could be a bit shy or reserved at first.
Well, power and growth are also common themes. Lance might gain new powers or learn to use his existing ones better in the crossover scenario. For example, in some fanfics, he combines his skills with elements from the other part of the crossover. Additionally, adventure is a big theme. Lance goes on various adventures in the new crossovers, facing different challenges and enemies. This allows for a lot of action and exploration in the stories.
