After the teaser, fans have called out 'Alpha' trailer for plagiarism. People flagged how Bobby Deol's character monitoring Alia Bhatt's character as a child from outside the cage was similar to Homelander's origin in 'The Boys'. The scene where Alia attacks Bobby, and he holds her by neck, was compared to Arya Stark attacking 'Night King' in 'Game of Thrones'.
