Phaeton

Phaeton is the son of Apollo or Helios.

Being mortal, his peers didn't believe he was the son of a god and told him to prove it. Phaeton went to his father Apollo and asked if for one day he could take his father's sun-chariot across the sky, and Apollo consented. Unfortunately Phaeton was unable to control the horses and Zeus killed him with a thunderbolt in order to protect the earth from being scorched by the sun's flames.
