¿Who is stronger, Power Girl or Watcher?

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.

The Watcher is a powerful and enigmatic character from the Marvel Universe, first appearing in the Marvel Comics series "The Fantastic Four" in 1963. He is a member of an ancient and advanced alien race known as the Watchers, who are sworn to observe and record the events of the universe, but not to interfere. The Watcher's story begins on the planet Uranus, where he was born as the son of a Watcher named Zoma and a mortal woman named Kymera. From a young age, the Watcher was trained in the ways of his people, and he quickly rose through the ranks to become one of the most respected and influential members of his race. As a Watcher, the character possesses a number of superhuman abilities, including strength, speed, agility, and durability. He also has access to advanced technology, including a number of powerful weapons and gadgets. Despite his powerful abilities, the Watcher is bound by his oath of non-interference, and he is not allowed to use his powers to directly interfere in the affairs of other beings. However, he has been known to bend or even break this oath on occasion, when he believes that it is necessary to prevent great harm or destruction. Throughout his long and storied career, the Watcher has observed and recorded countless events in the Marvel Universe, including the rise and fall of civilizations, the births and deaths of heroes and villains, and the struggles of ordinary people. Despite his seemingly passive role, the Watcher has had a profound impact on the Marvel Universe, and he is respected and feared by many of its greatest characters.
