Riptide

Riptide or Anaklusmos (in Ancient Greek, Ανακλυσμός) is the prized sword of Percy Jackson and his Primary Weapon, that is made of celestial bronze, a material that is effective only on gods, demigods, and monsters. When not in use it appears to be a BallPoint Pen, and when uncapped it becomes the sword Riptide/Anaklusmos. When used on mortals, the sword passes through them as if non-existent (shown in The Lightning Thief when Percy swings it at a street punk and The Titan's Curse when Percy accidentally swings it at Rachel). At least once, Riptide was seen as a rifle, and it was also described from a picture as "My sword was a metallic blur in my hands. It might've been a baseball bat or a lacrosse stick."

History
Riptide was formerly owned and used by Hercules and Pleione. The sword's dormant form was originally Zoë's hair clip, which she gave to Hercules to help him fight Ladon. It was he who forged it into the it's current form as a sword. Riptide draws its power from the ocean, which is why it works well for ocean spirits and children of Poseidon like Percy. Hercules did not give Zoë any credit for bypassing Ladon, leaving her to face the wrath of her father and sisters alone. This betrayal was the basis for her later hatred of male demigods, and the reason why she joined Hunters of Artemis.

Riptide is only wielded by a certain few in the series; Percy uses it multiple times, Chiron had it at Yancy Academy before he gave it to Percy and Hercules used it to defeat the dragon, Ladon.



The Lightning Thief
Riptide was given to Percy by Chiron in The Lightning Thief to fight Mrs. Dodds (Alecto, one of the three furies). Chiron gives Percy a ballpoint pen, which uncaped turns out be be Riptide. He tells him that the pen when lost would always return to him in his pocket, he also said that Riptide had a sad and painful past that they shall not go into. He also uses it to slay Medusa (AKA Aunty Em). Later he uses it to battle Ares at Santa Monica. Then Ares curses Riptide so that it would fail Percy when he needed it most.

The Titan's Curse
Percy has a dream in The Titan's Curse that shows Zoë giving her hairclip (which turns into Riptide) to Hercules. Chiron tells Percy the sword has a tragic history, which includes Hercules leaving Zoë to the wrath of her family, who are Atlas' daughters and Zoë's sisters, the Hesperides. This action of Hercules lead to her dislike of male heroes. During the fight with Atlas, Riptide becomes incredibly heavy and Percy is unable to use it. He then remembers what Ares had said when he fought him, and that his weapon would fail him when he needed it most. Percy can't defend himself and holds up the sky to allow Artemis to fight him instead.

The Last Olympian
Due to the line "A hero's soul cursed blade shall reap" in the Great Prophecy, Percy thought that the cursed blade was his own sword due to Ares' curse, which would cause Percy's sword to fail him in a time of great need (his fight with Atlas). The cursed blade turned out to not be Riptide, and was instead Annabeth's knife.

The Son Of Neptune
Percy wakes up with Riptide at the Wolf House. He is said to have used it to try to kill the Gorgons but they stayed alive. Reyna says that they used to have a few Celestial Bronze weapons in the armory at Camp Jupiter. Frank describes it as leaf-bladed with Greek writing on the hilt. For a short time upon entering New Rome, it was taken care of Terminus was able to keep it from returning to Percy's pocket, how he did so is unknown. Riptide is used as a light, both in the war games and when they first see the army heading toward Camp Jupiter. Riptide almost got frozen on Thanatos' chains until Frank helped him pull it free.

Appearance
In its dormant form, it is a disposable ballpoint pen that reads "Anaklusmos" on the side when not in use. Once the pen is uncapped, it transforms into its true sword form. Riptide is about 3 feet long including the hilt and weighs about 5 pounds with perfect balance so Percy can wield it very well. The hilt is about 4-6 inches long. Riptide is also said to have been shaped like a leaf, which is contrary to its appearance on the cover of The Lightning Thief and The Battle of the Labyrinth, where it has straight, triangular, diamond profile blade, instead. The hilt bends upward on the cover, which may be canon. It is almost impossible to lose as it is enchanted to appear in Percy's pocket if it is somehow lost. However, if Percy doesn't have pockets, it doesn't return, and this has led to a disadvantage, such as when the cannibals attacked in The Sea of Monsters.

Use
Riptide is used in close combat, and is light and balanced in its wielder's hands. Riptide can destroy monsters and hurt immortals. But, since it is made out of Celestial bronze, it cannot hurt or kill mortals, as "they aren't important enough". In The Titan's Curse Percy swings Riptide at a mortal named Rachel and nothing happens. When accidentally or even intentionally swung at mortals, the blade simply passes through them.

Riptide is used at least twice as a throwing knife, though that was for more of a distraction than an actual attack. In the books Riptide is summoned when uncapped, and stored away by recapping it on the tip, but in the movie it is summoned when clicked open. It is unknown how Percy stows back the sword in the film, although when Persephone hands him the bolt in the Underworld, it shows a zoom-up of his sword in his hand as it retracts into pen form. This is the only time that it is showed while being transformed. Riptide also reappears back into the pocket of whoever had it last whenever lost, misplaced, or even thrown.

In The Lightning Thief Percy defends himself against a gang of youths with Riptide, simply acting on instinct, but the blade simply passes through them, which infuriates the gang leader and causes him to chase Percy, Annabeth, and Grover down.

Film
"Chiron (handing Riptide to Percy): Take this to defend yourself. It's a powerful weapon. Only use it in times of severe distress.

Percy: This is a pen... This. Is. A. PEN!"

- Percy refuses to believe Chiron about Riptide

Riptide appears in the film, although the storyline is slightly altered. After Chiron scares the Fury out of the museum, he gives Percy the pen before he and Grover leave for Camp Half-Blood. Thus, he already has it when he fights the Minotaur. The pen is a click-pen, so that you 'click' it instead of taking the cap off. Interestingly, the name 'Riptide' is never mentioned at any point in the film, nor is it's connection to Poseidon or any other aquatic figure. However, it has a blue trident inscribed into the blade, near the hilt, so it can be assumed that it has something to do with a sea deity.

Trivia

 * The fact that Riptide turns from a pen into a sword may be a reference to the phrase "The pen is mightier than the sword."
 * Riptide was previously owned by Heracles and was given to him by Zoë Nightshade.
 * In the books, it transforms when uncapped; the movie version transformed when clicked.
 * In the Graphic Novel version of The Lightning Thief, Riptide is noticeably longer than both the books and the film. In fact, in the film, it's probably shorter than in the books, where it is about 3ft long; in the graphic novel, it appears to be a longsword -perhaps about 46 inches long, hilt and all, at most- a large weapon for a twelve year-old boy with little to no training whatsoever.
 * Percy has demonstrated at least twice that when stabbing the ground with Riptide he can make massive cracks similar to fissures: once when he destroyed the Williamsburg Bridge and more recently when he destroyed the fake Roman camp in Alaska. Whether this is his power wielded through Riptide or a power of Riptide's is unknown.
