Arion

"I will trample you to death, silly Chinese Canadian baby man."

- Arion to Frank, through Percy

Arion is the immortal equine son of the gods Ceres and Neptune.

History
Neptune once tried to woo Ceres while she was searching for her kidnapped daughter, Prosperpina. She rejected his advances and transformed herself into a mare to escape him. Transforming into a stallion, the god chased her until she was tired, producing Arion as a result.

The Son of Neptune
Arion is first mentioned by Hazel, when she sees him in Alaska in her old life. She follows the horse around all day, trying to get close enough to it to ride it, but Arion always runs away, eventually using his incredible speed to run far away and disappear for several decades.

Arion was later caught by the Amazons (which took them many years), and caged because he couldn't be tamed by any of the members in their ranks. Queen Hylla says that Arion would only be released by the strongest female warrior, but Arion hates all the Amazons. When Hazel arrives, she pulls gold from the ground and gives it to Arion. Later, during Hazel's, Percy's, and Frank's escape, she sets Arion free and the latter pulls Frank and Percy in a chariot while Hazel rides on his back. He follows Hazel all the way up to Alaska and helps her in her fight against the giant Alcyoneus. He pulls Alcyoneus out of Alaska into Canada as the giant cannot die in his homeland. Arion then carries the group back to Camp Jupiter in four hours and Hazel rides him into battle against the army of the giant Polybotes, which they eventually win.

Personality
Arion is highly confident and proud, not taking criticism well, and has a distinct independent streak. He particularly exhibits notably profane language.

Despite his faults, he is very loyal to Hazel whom he chose to be his rider.

Abilities
"...Arion runs like the wind over land and sea."

- Hylla to Hazel


 * He can run 800 miles per hour, traveling faster than sound.
 * He can create sonic blasts when traveling at super speed, probably due to breaking the sound barrier.
 * He can run up vertical slopes.
 * He can run on water. The reason for this can either be because he runs fast enough to keep from sinking into the water or it is because of his father, Neptune.
 * He posses superhuman strength, Arion is strong enough to easily drag beings as large as Alcyoneus for more than fifteen km.

Prophecy
According to Hylla, there is a prophecy stating that the most courageous female warrior would someday master Arion and ride him to victory, ushering in a new era of prosperity for the Amazons. The exact lines of this prophecy remain unknown. This might have come to pass since Hazel mastered Arion and now the Amazons are working with Camp Jupiter instead of against them.

Trivia

 * When riding Arion, Hazel did not feel as if she was going to fall off the horse or fly backwards, but Percy and Frank in the chariot felt the backwards pull from the speed they were going and almost fell off.
 * Arion is a cavalry horse, not a chariot/wagon pulling horse.
 * Arion curses a lot, however Percy leaves out the curse words when translating what Arion is saying to people.
 * Arion is slightly racist as well, considering that he called Frank a Chinese-Canadian baby man and that he was going to trample Frank to death.
