¿Who is stronger, Vision or Power Girl?

Vision is a Marvel Cinematic Universe (MCU) character who first appeared in the 2015 film "Avengers: Age of Ultron". Vision is an artificial intelligence created by the villain Ultron, but ends up joining the Avengers to fight him. Vision is a synthetic being with superhuman abilities, including superior strength, speed and endurance to an ordinary human being. In addition, he can fly and possesses energy abilities, such as the ability to shoot energy beams from his forehead. Unlike most UCM characters, Vision is a being composed of technology and organic matter, which gives him a unique appearance and an interesting perspective on life and humanity. In addition, Vision is a very intelligent character and often acts as an advisor and strategist for the Avengers. Vision's history in the UCM includes his role in the fight against Ultron and his contribution in defending Earth against threats such as Thanos. He has also been romantically involved with the heroine Scarlet Witch, which has been an important aspect of his story arc.

Power Girl, also known as Kara Zor-L, is a powerful superhero from the DC Universe. She is a member of the Justice Society of America and is one of the most formidable and respected heroes in the DC Universe. Power Girl's story begins on the planet Krypton, where she was born as the cousin of Superman. Like Superman, Power Girl possesses a number of superhuman abilities, including strength, speed, agility, durability, and the ability to fly. Unlike Superman, however, Power Girl's powers are not derived from the sun, but rather from a natural genetic mutation. As a result, her powers are not limited by the presence of a yellow sun, and she is able to use her powers to their full extent at all times. In addition to her physical powers, Power Girl also possesses a number of mental abilities, including telepathy and telekinesis. She is also able to manipulate energy and matter, allowing her to create powerful energy blasts and even reshape the environment around her. Throughout her long and storied career, Power Girl has faced many challenges and fought against a wide range of villains, including Lex Luthor, Brainiac, and the Joker. Despite these challenges, she has always emerged victorious, making her one of the most respected and admired heroes in the DC Universe.
