Perachel is the ship of Percy Jackson and Rachel Elizabeth-Dare, From "Percy Jackson and the Olympians" And "Hero's of Olympus" book series by Rick Riordan. Although many people prefer Percabeth, there are a few fans who choose Rachel over Annabeth.
During "The Last Olympian" Percy and Rachel were driving Percy's step-father's Prius. When Charles Beckendorf landed on the hood, telling Percy he was needed at Camp, Rachel kissed him good bye. One of the most defined Perachel moments.
Perachel in the PJO fandom is the ship that must never be shipped. It's made up of Percy Jackson and Rachel Elizabeth Dare. It is obviously impossible cause ya know, percabeth ftw. Perachel can't compete with everyone's OTP.
Oh my gods did you see the perachel ship sink? PERCABETH FTW!
