I had this random thought and didn’t know if I was overthinking the MCU or the storyline between these two.

When Gamora and Thanos meet with Red Skull he immediately says something to the effect of “Gamora, daughter of Thanos.” Perhaps it was assumed by everyone that this makes sense since Thanos essentially kidnapped her as an orphan, but is there a chance that Thanos is the biological father of Gamora? Does he go to Gamoras homeplanet to kill half of the population as well as get his daughter back?

During the flashback on Gamora’s homeplanet, none of the people that I noticed have the silver defining features on their faces like Gamora does. It seems reminiscent to the designs on Thanos’ armor so I didn’t know if that was a subtle hint towards their connection or not.

Any thoughts or discussion on this? Does this make sense or am I overthinking all of this?
