Ego in Guardians of the Galaxy Vol. 2
A lot of MCU fans instantly found Ego likable the moment he was introduced in 2017’s Guardians of the Galaxy Vol. 2 not only because he’s the father of Chris Pratt’s Peter Quill, who is the main protagonist of the movie, but also because he’s played by the beloved actor, Kurt Russell.
But true to his name, Ego was eventually revealed to be a self-serving megalomaniac who’s willing to kill the myriad women he’s seduced and the children he’s sired to achieve his ultimate despicable goal: remake the entire universe via an omnicidal extinction-level event that would eradicate all life in the universe but himself.
