I mean, how can one not answer Superman? Everything you said about Flash, PLUS crazy levels of superstrength, durability, senses, flight, heat vision, superbreath, freezebreath, virtually unaging, superheal, and oh yeah, Kryptonians are immune to mind control and are superintelligent.
My only threat is from a fictional material that even if it exists would be super-rare on Earth since there's no way the debris would get here since it can't travel faster than the speed of light without a ship.
AND unlike Supergirl or Martian Manhunter or Flash, I don't have the pathos. Supergirl remembers Krypton and the people lost. MM lived through a holocaust. Flash lost his parents at a young age (depending on what version you're reading).
Superman lost his bio parents, but doesn't remember them. He was raised by the Kents.
