¿Who is stronger, Groot or Abraxas?

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.

Abraxas is a powerful cosmic entity from the Marvel Comics universe and an enemy of the superhero team the Fantastic Four. He is a being of immense power who exists outside of the normal boundaries of reality and time. Abraxas possesses a wide range of superhuman abilities, including super strength, super speed, energy projection, and the ability to manipulate reality. He also has access to advanced technology and magical powers, making him a formidable opponent for any superhero. As a cosmic entity, Abraxas is driven by a desire to destroy all reality and create a new universe in his own image. He has clashed with the Fantastic Four and other superheroes numerous times in his quest to achieve this goal, and has proven to be a formidable and dangerous foe.
