¿Who is stronger, Bills or Groot?

Beerus, also known as Bills in some translations, is a pivotal character in the "Dragon Ball" series, introduced as the God of Destruction for Universe 7. Resembling a purple, anthropomorphic feline, Beerus maintains cosmic balance by destroying planets, a role that contrasts with the Supreme Kais, who are responsible for creation. His first appearance is in the film "Dragon Ball Z: Battle of Gods," where he seeks the Super Saiyan God to challenge his strength, leading to a monumental battle with Goku. Despite his formidable power and often capricious nature, Beerus develops a complex relationship with Earth's heroes, oscillating between adversary and ally. His abilities include immense strength, speed, energy projection, and a technique called "Hakai," which allows him to erase entities from existence. Beerus's character adds depth to the series by exploring themes of divinity, power, and the delicate balance between creation and destruction.

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.
