I’ve been checking gallery for Dormammu’s quotes, and found out that he has 2 sounds (75 and 88) that are never used in game. Can this be a beggining and ending quote he says to a future DLC character? We will have to wait and find out.
75 - "I have waited a Millenia for a chance to destroy you."
88 - “And they call you the Lord of Chaos? Hah…I claim that tittle for myself now.”
P.S. Also found a hidden quote for Ghost Rider “I have this contract with Mephisto i want you to look at”.
