An appropriate way to prelude a fight for your life is to threaten, boast or insult the opposition. Here are some of the best intros in the game, including the newest DLC, Omniman.
Omni-Man: You're no match for a Viltrumite, Kratos. Kratos: I have killed gods before. Homelander: So you've actually killed gods before? That's actually impressive. Kratos: But you are no god or hero.
