One comic character I have grown to have a lot of respect for is the Martian Manhunter. While usually compared to Superman for their powers I think where the comparisons truly lie is in the topic of immigration. Superman was raised on Earth from infancy, never truly growing up as an alien. J’onn J’onzz meanwhile was born and raised on Mars with a job and was raising a family. In the Silver Age, Mars wasn’t yet a desolate wasteland and J’onn coming to Earth is more akin to going abroad.
