Summary
Hercules is having trouble dealing with Adonis, so when he mentions it to his father, Zeus tells him to show him who's in charge. Hercules warns it's not that easy, so to prove him wrong, Zeus spends a day as a teenager; at first as a god, then at Hermes' request, as a mortal. While he was very popular as a teen god, as a mortal Zeus is just like everyone else, subject to humiliation - and also, as Hades learns from the Fates, death. In an attempt to be rid of Zeus once and for all, he sends his troublesome dog Cerberus after Zeus while he's still mortal. Zeus gains his godhood back and defeats Hades, but learns a valuable lesson about how hard it is being mortal - though not before getting back at Adonis.
