Alright breakdown. The main thing is he wasnt born on Earth different planets so his birth chart would be unfathomable. But as far as personality and such seems to be pretty good evaluation...using Earth astrology which wouldnt apply technically but as comparison...fun fact both current Superman and Wonder woman are played by Tauruses in real life as the energy that most translates. When it goes from theoretical to what actually "fits".
No leo mars and ascendant sure but not sun. He does what he does to protect and has never required or even acknowledged gratitude and appreciation. He does what he does regardless. Oh and then there is the fortress of solitude. How dies that not scream cancer to anyone?
Recharged by the sun and his suit is pretty flash for the time. That giant "S" screams look at me.So ya let's go with leo mars and ascendant.
