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.
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.
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.
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.
A great theme would be Lance's role in different battles. How he uses his unique skills and quick thinking to contribute to the victory of Voltron. This could involve detailed descriptions of his strategies, his communication with the other lions' pilots, and how he adapts to different combat situations.
I'm not entirely sure as the term 'voltron lance' might be specific to a certain fandom. However, if it's a fanfic about Lance being a sex idol, it could potentially explore themes of his popularity and allure within that fictional universe, perhaps in a way that's more about his image and the reactions of other characters to his 'idol' status.
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 great Lance and dragon - related fanfic could be 'Lance's Dragon Bond'. In it, Lance discovers a hidden power that involves a connection with a majestic dragon. The story often has him using this newfound bond to help the Voltron team in unique ways. It's full of action and also explores Lance's character growth in relation to this extraordinary ability.
