¿Who is stronger, Groot or Ego?

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.

Ego the Living Planet is one of the most unique and powerful villains in the Marvel Universe. First appearing in Thor #132 in 1966, Ego is a sentient planet with the ability to manipulate matter and energy on a massive scale. Ego was originally a planet that formed naturally in space. However, over time, Ego developed sentience and began to manipulate its own physical form. Ego's powers allow it to shape-shift and even create life on its surface. Ego's consciousness also extends beyond its physical form, allowing it to communicate telepathically and project its will over vast distances. Despite its immense power, Ego is often depicted as a lonely and isolated entity. Ego has spent eons drifting through space, searching for meaning and purpose in its existence. Ego's interactions with other beings are often colored by its desire for companionship and connection. Ego has clashed with numerous superheroes over the years, including Thor, the Fantastic Four, and the Guardians of the Galaxy. Ego's powers and strength make it a formidable opponent, and its vast size and ability to manipulate matter and energy make it nearly invincible. Overall, Ego the Living Planet's superpowers and strength make it one of the most unique and interesting villains in the Marvel Universe. Its complex motivations and desire for companionship add depth and nuance to its character, making it more than just a one-dimensional villain.
