Here's what you need to know about him:
* He transports souls to the Underworld. He is the ferryman who takes the souls of the dead across the River Styx to the Underworld.
* He is not a kind character. Charon is gruff and demanding. He only allows those with proper payment to cross the river.
* He plays a key role in the story. When Percy Jackson and his friends arrive at the River Styx, they have to bribe Charon to get across. This sets the stage for the climax of the story.
Charon is a significant figure in Greek mythology. He is a powerful and fearsome being who holds the power to control passage to the Underworld. In the *Lightning Thief*, he serves as a reminder of the dangers and mysteries that lie beyond the mortal world.
