The planet Krypton is destabilized from the mining of the planetary core.
Just before the planet explodes, Krypton’s supreme council chief advisor Jor-El infuses the genetics codex into his infant son, Kal-El, the first naturally born Kryptonian child in centuries.
Jor-El manages to send Kal-El in a spacecraft toward Earth before being killed by General Zod during an uprising. Kal-El lands in Kansas, where he is adopted by Jonathan and Martha Kent and named Clark.
As he grows older, he develops superhuman powers that Jonathan urges to keep hidden, even refusing Clark’s help years later during a tornado incident where he loses his life. Burdened with guilt over Jonathan’s death, Clark travels the globe hiding under various aliases seeking a purpose in life.
