Question

What did the Riptide sword give percy invisible or fly or a better fighter

Answer 1

Answer: Riptide is used in close combat and is perfectly 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 humans, as "they aren't important enough." As a result, when accidentally or even intentionally swung at humans, the blade simply passes through them. For example, in The Titan's Curse, Percy swings Riptide at a human named Rachel Elizabeth Dare by mistake and nothing happened to her. 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 Chase, and Grover Underwood into Crusty's Water Bed Palace

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 Laistrygonian Giants attacked Percy in the sea of monsters

Answer 2

The disguised sword that Percy’s father, the Greek god Poseidon, leaves for him is a symbol for Percy himself. Like the sword—which is variably referred to by its Greek name, Anaklusmos; its English name, Riptide; and its disguise as a pen—Percy has several warring facets of his identity. Just as the sword can masquerade as a normal capped pen, Percy has gone through life for years believing that he’s a normal kid. And yet, just as the pen grows into the magnificent sword when uncapped, Percy, too, grows into a hero and begins to embody the connotations of his real name, Perseus, when he finally discovers who and what he is: a demigod. That the sword came from Poseidon also drives home Percy’s divine parentage and his potential for greatness, another aspect of Percy’s identity that he struggles to come terms with.
