His real name is T'Challa and he is played by the late actor Chadwick Boseman. T'Challa is the king of Wakanda, an African country that has managed to hide from the outside world thanks to its advanced technology and its deposit of Vibranium, a valuable mineral. In addition to being a wise and just ruler, T'Challa is also the protector of Wakanda and its people as the Black Panther. As Black Panther, T'Challa possesses superhuman abilities granted by a special herb and Vibranium ore. His abilities include strength, speed and endurance superior to those of an ordinary human being. He is also a highly skilled combatant, capable of defeating multiple opponents at once, and has advanced Wakandan technology, such as his Vibranium suit, retractable claws and propulsive boots. Black Panther's history in the UCM includes his role in the fight against the cosmic villain, Thanos, and his struggle to protect his country and people from external and internal threats. In addition, T'Challa has also had to face personal challenges, such as the duel for the crown of Wakanda and the revelation of his family's dark secrets. Black Panther has become one of the most popular characters in the MCU and has been praised for his positive portrayal of African culture and his impact on diversity and inclusion in the film industry.
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.
