¿Who is stronger, Lobo or Groot?

Lobo is a powerful and dangerous character from the DC Universe, first appearing in the DC Comics series "Omega Men" in 1983. He is an intergalactic bounty hunter and assassin, and is one of the most feared and respected figures in the DC Universe. Lobo's story begins on the planet Czarnia, where he was born as the son of a scientist named Professor Velorkam. From a young age, Lobo displayed extraordinary strength and durability, and he quickly rose through the ranks to become one of the most feared and respected bounty hunters in the galaxy. As a result of his unique physiology, Lobo possesses a number of superhuman abilities, including strength, speed, agility, and durability. He is also immune to all forms of injury and disease, and is virtually indestructible. In addition to his physical powers, Lobo also has access to a wide range of advanced technology and weaponry, including his signature spacehog motorcycle and a number of powerful weapons, such as his regenerating chainsaw. Throughout his long and storied career, Lobo has clashed with many of the DC Universe's greatest heroes, including Superman, Batman, and the Green Lantern Corps. Despite their best efforts, these heroes have often struggled to defeat Lobo, making him one of the most formidable and dangerous villains in the DC 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.
