¿Who is stronger, Supergirl or Vision?

Supergirl is a powerful superheroine hailing from the planet Krypton. She is the cousin of Superman and shares many of his superhuman abilities, including super strength, super speed, and the ability to fly. Supergirl's real name is Kara Zor-El, and she was sent to Earth as a teenager by her parents just before the destruction of Krypton. Like Superman, Kara was raised by adoptive human parents and learned to hide her powers for fear of being discovered. However, she eventually decided to embrace her true identity and use her powers for good, becoming the superheroine known as Supergirl. In addition to her physical abilities, Supergirl also possesses a range of other powers, including heat vision, super breath, and enhanced senses. She is also highly intelligent and skilled in a variety of fields, including science and technology. As Supergirl, Kara fights to protect Earth and its inhabitants from a variety of threats, including supervillains, alien invaders, and natural disasters. She is a member of the Justice League and often teams up with her cousin Superman and other superheroes to defeat their enemies and save the world. Despite her incredible strength and abilities, Supergirl is still a young woman learning to navigate the complexities of life and find her place in the world. She struggles with her identity as both a superhero and a human being, and strives to balance her duties as a hero with her personal life and relationships. Overall, Supergirl is a strong, courageous, and compassionate hero who uses her powers to make a positive difference in the world.
