...When asked to comment on the rumors that Gamora, Guardian of the Galaxy is his daughter, Thanos answered with a proud smile.
“Why, yes she is indeed. And I would like to add, on the record, that I am very proud of her.”...
....Responding to the fact that the alleged father-daughter pair have actually opposed each other for months in the galaxy’s so-called “infinity war”, the Mad Titan clarified his position.
“Gamora is fiercely independent--emotionally, psychologically and ideologically. She stands up for her beliefs regardless of the consequences-- something that I like to think she learned from me.”...
...And finally, when confronted with the reality that Gamora would presumably have to confront each other at some point throughout the war, Thanos Titan shut down the conversation with the brutal efficiency that the galaxy has come to expect from its most infamous warlord:
“The fact that we are currently in disagreement has no bearing on our relationship nor ever will... Hmm, why so silent? Would you like some cake?”...
