¿Who is stronger, Quicksilver or Groot?

Quicksilver, also known as Pietro Maximoff, is a Marvel Comics superhero who possesses the ability to move at superhuman speeds. He was created by Stan Lee and Jack Kirby and first appeared in X-Men #4 in 1964. Quicksilver's powers are a result of his mutated physiology, which allows him to move at incredible speeds, run across water and up walls, and even create afterimages of himself. His reflexes and reaction times are also enhanced, making him incredibly difficult to hit in combat. In addition to his speed, Quicksilver is also a skilled hand-to-hand combatant, having been trained by his father, Magneto, in martial arts and strategy. Quicksilver's history in the Marvel Universe is complex and has evolved over time. He and his twin sister, Scarlet Witch, were initially introduced as members of the Brotherhood of Evil Mutants, led by their father Magneto. However, they later defected and joined the Avengers, where they became important members of the team. Quicksilver has also had numerous solo adventures, where he has faced off against some of the most dangerous villains in the Marvel Universe. His speed and agility have allowed him to take on opponents much stronger than himself, and his tactical intelligence has allowed him to outmaneuver even the most cunning of foes. In addition to his comic book appearances, Quicksilver has also appeared in multiple adaptations in other media, including the X-Men and Avengers films. He remains a beloved and iconic character in the Marvel Universe, known for his lightning-fast speed and unwavering determination.

Groot is a character in the Marvel Cinematic Universe (MFCU) who is also part of the Guardians of the Galaxy. Groot is an extraterrestrial being who belongs to the Flora colossus species, a race of arboreal humanoids capable of regenerating and controlling their own plant bodies. In the UCM films, Groot is portrayed as loyal and brave, yet innocent and sometimes childlike in nature. Groot has a very distinctive personality and his vocabulary is limited to the phrase "I am Groot", although other characters seem to be able to understand his meaning based on context and intonation. Groot possesses superhuman strength and stamina thanks to his wooden body, as well as the ability to regenerate and grow his limbs at will. He can also throw sharp spines and control the vegetation around him. Throughout the UCM films, Groot plays an important role in the fight against the forces of evil, even sacrificing himself to save his friends on one occasion. After his sacrifice, a new Groot is born from a branch, meaning the character is essentially immortal.
