I'm asking about the MCU version of Thanos, but I'll accept answers sourced from the comics if no MCU answer is available (which I think is likely).
Thanos comes from the planet Titan. We see in Infinity War that Titan was destroyed, presumably in a resource-driven civil war previously predicted by Thanos.
We also see, in Infinity War and in Endgame, that Thanos can fight off even the most powerful Marvel heroes at need.
I'm wondering if the other inhabitants of Titan had strength and abilities similar to Thanos. Because if there were a whole planet of beings like Thanos, it seems odd that they wouldn't have just seized whatever resources they wanted from others.
