¿Who is stronger, Kang or Groot?

Kang the Conqueror is one of the most powerful and dangerous villains in the Marvel Universe. Throughout his history in the comics, he has travelled through time and conquered countless worlds and realities. In the Marvel Cinematic Universe, Kang was first introduced in the Disney+ series "Loki", where it was revealed that he is an immortal being who has ruled different timelines for centuries. Kang's superpowers are the result of his advanced technology and superhuman intelligence. He has invented devices that allow him to travel through time, control reality and alter history at will. In addition, Kang is an expert in military strategy and has superhuman strength and physical endurance. In the Marvel Cinematic Universe, Kang is played by actor Jonathan Majors, and is expected to play a major role in future films and television series. As one of Marvel's most powerful villains, Kang poses an unrivalled threat to the heroes of the Marvel Universe and promises to be a formidable adversary in the upcoming adventures of the Marvel Cinematic Universe.

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.
