Dionysus
Dionysus was the god of wine. He was the son of Zeus and the mortal heroine Semele.
Dionysus rescued Ariadne after she had been abandoned by Theseus. Dionysus also saved his mother from the Underworld, after Zeus showed her his true nature as storm god and consumed her in lightning.
It was Dionysus who granted Midas the power to turn whatever he touched into gold, and then was kind enough to take the power back when it proved inconvenient.
