Don't worry Hercules. I will come to the underworld and save you. You play a vital role in humanity's future so you must survive till the moment.
Zeus, as said goes to the underworld to get Hercules but he is met with Cerberus.
Get out of the way Cerberus, I need to save Hercules. His role in humanity is far too important for him to die now.
I am sorry Zeus, I am the guardian of the underworld so I don't let anyone take a spirit to the surface.
Zeus tried to convince Cerberus to let Hercules go, but Cerberus wouldn't listen.
Cerberus, I had enough. I challenge you to a battle. If I win Hercules comes with me. I accept whatever the condition is if I lose.
I accept your challenge Zeus. However if you lose, you must leave and never return to the underworld again.
Zeus and Cerberus had a long battle. Sometimes Zeus had the upper hand and sometimes Cerberus did. After sometime, Zeus was getting fed up and used his most powerful spell, which manage to defeat Cerberus.
Thanks, Cerberus. Next time, I won't let this happen.
Zeus, you won. So I accept defeat. Now I will go and get Hercules. Next time, make sure this dosen't happen. Otherwise I wouldn't be so nice.
Here Zeus, Hercules. Now go before I change my mind.
Oh, you will find out....... eventually.
So Zeus, why did you save me though? I thought getting someone from the underworld is not allowed unless it is a emergency case.
