Another great storyline could involve a cross - dimensional rift that brings characters from Arrow's world into Supergirl's and vice versa. This would create a lot of chaos as the characters have to adapt to the different rules and environments. For example, Oliver might struggle with the presence of aliens in Supergirl's world, while Kara has to deal with the more gritty and crime - ridden Star City. It could also lead to some interesting character pair - ups and new friendships or rivalries.
A third popular storyline might be a shared origin for a new threat. Perhaps a scientific experiment gone wrong in both cities at the same time, creating a new type of super - powered being. Supergirl and Arrow would have to combine their skills and resources to take on this new enemy. Supergirl's super strength and flight could be paired with Arrow's archery skills and stealth to take on this common foe.
Another interesting idea is a mind - control situation. A powerful telepath takes control of some of the heroes and villains in their respective cities. Flash, Arrow, and Supergirl have to find a way to break the mind - control. They start by finding the source of the telepath's power. Along the way, they discover that the telepath has a tragic past that led to this misuse of power. They try to reason with the telepath while also fighting off the controlled allies and villains.
One popular storyline is when Flash and Supergirl team up to fight a common enemy from another dimension. This allows for a lot of action and showcases their different powers working together.
One great storyline could be a villain that is causing chaos in both Arrow's Star City and Supergirl's National City. The two heroes team up, with Arrow using his combat skills and Supergirl using her superpowers to take on the baddie. They might initially have some differences in their approaches, but over time, they learn from each other and form a strong bond.
One popular storyline is where Flash and Supergirl team up to fight a common, powerful enemy like a super - villain from another dimension. They combine their speed and strength in unique ways to save the world. Another is a more character - driven plot where they develop a romantic relationship. Flash's quick - witted charm and Supergirl's strong - willed nature make for an interesting dynamic. There are also storylines where they swap powers temporarily, leading to humorous and action - packed situations as they learn to use each other's abilities.
One great storyline could be them teaming up to fight a common enemy like a powerful meta - human who is causing chaos in both of their cities. They could start off not trusting each other fully due to their different methods but then grow to respect one another as they see the value in each other's skills.
The Reverse Flash could be an exciting villain in a Supergirl Arrow crossover. His ability to move at super - speeds would make him a formidable opponent for Supergirl. He could also mess with Arrow's timeline, creating chaos in both their worlds. Imagine him going back in time to prevent Supergirl from arriving on Earth or changing events that led to Arrow becoming a vigilante. His manipulative nature and his connection to the Speed Force would bring a whole new level of complexity to the crossover story.
There are several popular storylines in Power Girl Supergirl fanfiction. One is the 'training together' storyline. This involves them learning from each other's fighting styles and powers, which helps them grow as superheroes. It also shows their mutual respect for each other's abilities. Another popular plot is the 'protecting a city' storyline. They are often pitted against powerful villains who are threatening a major city. This showcases their heroism and their different approaches to saving the day. The 'family reunion' storyline is also quite liked. It delves into their Kryptonian heritage and how they might be related in some way, exploring their family bonds and how that affects their actions as superheroes.
One creative storyline could be a Supergirl from an alternate universe where she has different powers. For example, instead of super strength and flight, she has the power to manipulate time on a small scale. This could lead to interesting situations where she has to fix small time - related disasters in her city. Another could be a story where Supergirl teams up with an unexpected character, like a reformed super - villain from the DC universe, and they have to face a new, powerful threat together.
Well, a great plot for Supergirl Arrow crossover fanfiction could be centered around a common enemy from another dimension. This enemy has technology that nullifies Supergirl's powers and Arrow's skills, so they have to rely on their wits and each other's unique strengths. For example, Supergirl could use her heat vision in a creative way to expose the enemy's weaknesses while Arrow uses his archery skills to set up distractions. They could also meet some interesting characters from the other dimension during their adventure.
One idea could be that an alien threat emerges which requires the skills of both Arrow's team in Star City and Supergirl in National City. They have to combine their combat styles, with Arrow's more grounded and stealthy approach and Supergirl's super - powered attacks. For example, Arrow could use his trick arrows to create distractions while Supergirl takes on the stronger alien foes directly.
