The Lightning Thief
by Rick Riordan

Chiron/Mr. Brunner Character Analysis

Mr. Brunner is Percy’s mentor. Mr. Brunner is first Percy’s Latin teacher at Yancy Academy. He’s in a wheelchair, owns a number of Greek battle replicas that he uses for study games, and takes a special interest in Percy that Percy doesn’t quite understand. However, Mr. Brunner is the only teacher whom Percy cares about impressing. Once Percy ends up at Camp Half-Blood, he discovers that Mr. Brunner was just a disguise—Mr. Brunner is actually Chiron, the mythical centaur who trained classical Greek heroes like Theseus and Hercules. When in his Mr. Brunner form, which he often takes so he fits in buildings, Chiron’s horse body folds up into the wheelchair. Chiron is calm and kind, but he’s also exacting and he demands a high level of performance from his mentees. He also seems to know more than he lets on; Percy suspects that Chiron has heard a prophecy from the Oracle that mentions him, Annabeth, and Kronos, but Chiron is forbidden from talking explicitly about it. Instead, he contents himself with doing what he can to prepare Percy for his quest, including by passing on Poseidon’s sword, Riptide. Chiron is unable to provide assistance during Percy’s quest, but he helps Percy interpret events after his return. He warns Percy that Percy must wait and rack up training hours if he wishes to take on Kronos and Luke, since he’s not in a place yet to successfully face them. Despite Percy’s admiration for and trust of Chiron, he chooses to go against what he thinks Chiron wants and goes home for the school year.

Chapter 5 Quotes

“Will Grover be okay?” I asked Chiron.

Chiron nodded, though he looked a bit troubled. “Old Dionysus isn’t really mad. He just hates his job. He’s been...ah, grounded, I guess you would say, and he can’t stand waiting another century before he’s allowed to go back to Olympus.”

Explanation and Analysis:

As Mr. D leads Grover away for an uncomfortable chat about his subpar performance on his keeper assignment, Chiron explains to Percy why Mr. D is so cantankerous and unhappy: Mr. D committed some kind of transgression, and now his punishment is to run Camp Half-Blood. Though the novel never elaborates on what exactly Mr. D did to deserve punishment, the thought of a powerful god like Dionysus being grounded is funny. Through this humor, Riordan begins to humanize the gods, which shows Percy (and the reader) that though the gods may be powerful figures, they nevertheless possess distinctly human qualities. They make mistakes, receive punishments, and hate their jobs—just like many humans do.

This is shocking for Percy, mostly because up until this point, the gods have existed in his mind as archetypes devoid of real personalities or quirks. This moment forces Percy to recognize the humanity of the gods and to understand that he must treat them like gods, with respect and reverence, but he must also think of them as though they’re human. Like humans, they’re multifaceted and complicated, and it’s reductive—and, Percy discovers, impossible—to think of the gods as one-note individuals.

“You mean the Greek gods are here? Like...in America?”

“Well, certainly. The gods move with the heart of the West.”

“The what?”

“Come now, Percy. What you call ‘Western civilization.’ Do you think it’s just an abstract concept? No, it’s a living force. A collective consciousness that has burned bright for thousands of years. The gods are part of it.”

Chapter 9 Quotes

I felt so relieved I wanted to cry, though I didn’t think that would be very heroic. Grover was the only friend I’d ever had for longer than a few months. I wasn’t sure what good a satyr could do against the forces of the dead, but I felt better knowing he’d be with me.
