Some fanfics have a plotline where Snart and Barry are in a mentor - mentee relationship. Barry, with his good - natured heroism, tries to teach Snart about the value of using his powers for good. Meanwhile, Snart imparts his street - smart knowledge and survival skills to Barry. This creates a really interesting exchange of ideas and values between the two characters. There are also fanfics where they are pitted against each other in a battle of wits, which is always exciting as both are very intelligent in their own ways.
One great 'Barry Allen Leonard Snart fanfic' is 'Frost and Flash'. It has an interesting take on their relationship, exploring how their different powers and personalities interact. Another one could be 'The Alliance of Speed and Cold' which delves into them teaming up for a common goal and the development of their friendship during the process.
One idea could be that Barry and Leonard are forced to team up against a new meta - human threat that neither can handle alone. They start off distrusting each other but as they face challenges together, they gradually develop a mutual respect. For example, the meta - human has the ability to manipulate time in a way that affects both of their powers. Barry's speed is thrown off and Leonard's cold gun malfunctions. So they have to figure out how to work around these issues and defeat the enemy.
Barry in fanfiction could be more open - minded towards Snart. Instead of just seeing him as a cold - hearted criminal, he might start to understand the reasons behind Snart's actions. This could be due to some shared experiences they have in the fan - created story. Leonard Snart's personality might be more adaptable. He could be more willing to change his ways or at least consider other options when he spends more time with Barry. In the original shows, they were more on opposing sides with little room for compromise, but in fanfiction, their personalities can be adjusted to allow for a more interesting and complex relationship.
A common plotline is the development of a romantic relationship between them. In many fanfics, they start as friends or colleagues in S.T.A.R. Labs, and gradually feelings develop. This can be a slow - burn type of story that keeps readers engaged.
One interesting plot idea could be Snart using his cold - gun in the magical world of Harry Potter. Maybe he has to face off against a dark wizard and his cold - based technology gives him an unexpected advantage. Another could be a story where Snart is accidentally transported to Hogwarts and has to find a way back home while dealing with the magical chaos around him.
One possible plotline could be Naruto discovers a way to travel to Barry Allen's world. He then tries to learn from Barry about his speed powers and how to use them in his own ninja - fighting style. Another could be that Barry Allen accidentally ends up in the Naruto universe and Naruto becomes his guide, all while being in awe of Barry's abilities.
It gives fans a chance to fill in the gaps. The official stories might not focus as much on Barry's relationship with his brother. Fanfic writers can then take that and create detailed stories. They can add depth to the characters, show their backstories, and create scenarios that the official comics or shows might not have explored yet. This makes the fanfics really engaging and interesting for fans who want more of that family aspect in the Flash world.
Love and redemption are also quite common. Maybe Snart, who has a more morally ambiguous past, finds a kind of redemption through his relationship with Sara. And of course, there's the theme of trust. Since they both operate in a world where trust is hard - earned, fanfics might focus on how they build that trust with each other. There could be stories where they start off as reluctant allies and gradually become more than that.
Another plot could involve her teaming up with other superheroes' children to form a new generation of heroes. They would have to learn to work together, overcome their differences, and fight against a powerful enemy that the older heroes couldn't defeat on their own.
One plot idea could be that the adopted Barry Allen discovers he has a unique connection to a parallel universe where his birth family resides. He then embarks on a journey to find out more about his origins while still maintaining his relationships in his adopted family. Another could be that he uses his speed - force powers in a creative way to solve problems within his adopted family, like preventing a family member from making a big mistake in time. A third idea is that an enemy targets him specifically because of his adopted status, thinking it makes him vulnerable, but Barry proves them wrong.
