what a great fucking character
basically just superman but better in so many ways
Non white passing
Actually has to deal with being an alien (both senses of the word)
Fought in a revolution
Had a family and a complete life instead of not even remembering his homeworld
Way cooler powerset (shapeshifting, telepathy, density shifting)
Shows the struggles of immigrants and refugees to acclimate to their new home
Heart and soul of the justice league
Addicted to oreos
he's criminally underrated and underused. may J'onn J'onzz once again live on a red planet
Dude the fucking greatest moment in any comic book ever was when MM put on Dr. Fate's helmet. Shit is so fucking cool.
Also you forgot to mention the other cool depth to his character where the only other martians he encounters are handled in an interesting way
