Groot first appeared on screen in Marvel's Guardians of the Galaxy in 2014, voiced by Vin Diesel, who recorded the line 'I am Groot' in many different inflections for scenes throughout the film. The joke became one of the movie's most quoted elements because other characters understand Groot perfectly despite his limited vocabulary. Clips of the line spread across YouTube, TikTok, and soundboards as a shorthand for cute confusion or stubborn repetition, and it remains closely linked to Groot's appearances in later Marvel films and the sequel series.
