Supergirl has super strength which allows her to lift extremely heavy objects. She also has heat vision that can be used as a weapon. And of course, she can fly. Wonder Woman, on the other hand, has super strength as well, but she has unique weapons like the Lasso of Truth which can force people to tell the truth, and her indestructible bracelets which can deflect bullets.
Supergirl could potentially win. She has the same powers as Superman under a yellow sun. Her heat vision can be extremely powerful. If she uses her speed and heat vision in a coordinated way, she could overpower Wonder Woman. Also, Supergirl might be more adaptable in different environments as she has had to face various threats on Earth and in space.
Well, a 'lemon fanfic' usually implies some sort of romantic or perhaps more intimate relationship in fan - created stories. However, in the case of Supergirl and Wonder Woman, it could be really interesting. It might explore how their different powers and personalities interact in a more emotional or even romantic context. But such fanfics may not be in line with the original canon of the characters in all aspects.
One common theme is female empowerment. Both Supergirl and Wonder Woman are strong female characters, and fanfics often highlight their power and independence. They are shown as capable of handling any situation on their own or together, which is inspiring for many readers.
They both possess superhuman strength. In their adventures together, Supergirl and Wonder Woman often rely on their physical power to battle enemies. This strength allows them to take on powerful foes and emerge victorious. Also, they both have a kind heart. They care about the people they are protecting and always try to minimize collateral damage during their battles.
In a story, Supergirl and Wonder Woman were summoned to an alternate dimension. There, they had to face a dark version of themselves created by an evil sorcerer. At first, they were confused and a bit afraid. But then they realized that they could use their own goodness and the bond between them. Supergirl's heat vision and Wonder Woman's bracelets clashed with the dark versions. After a long and tough battle, they managed to overcome the dark versions and break the spell of the sorcerer, saving the alternate dimension.
Well, while DC Comics has been exploring more diverse relationships in recent years, as of now, there is no official lesbian storyline for Wonder Woman and Supergirl. But the idea has caught the imagination of many fans, and it could potentially be something that DC might consider in the future for an alternate universe or a special storyline. It could add a new dimension to their characters and how they interact with each other, both in terms of their heroic deeds and their personal relationships.
Maybe in the fanfic, there's a threat that specifically targets strong female superheroes. Supergirl and Wonder Woman team up to fight against it. During the fight, they get separated from their allies and are forced to rely only on each other. This situation makes them see each other in a new light. They start to share their deepest fears and desires, and gradually, a romantic relationship blossoms between them. However, they have to keep it a secret from their friends and the public at first because they're not sure how it will be received.
A powerful alien warlord could be the main villain. This warlord might have his eyes on Earth because of its resources or strategic location.

They would need to figure out his weaknesses and come up with a plan to stop his invasion.
One popular Supergirl and Wonder Woman fanfic is 'Alliance of Power'. It focuses on their combined efforts to face a new and powerful enemy that neither could defeat alone.
