Arquiusprite is Dirk Strider's sprite after being prototyped with the remains of Equius Zahhak by Gamzee Makara and subsequently with Lil Hal by Dirk. His name is a combination of AR for Auto Responder and Equius. Similar to how other B2 sprites have a combination of the zodiac symbols of the two trolls used to prototype the sprite on them, Arquiusprite's symbol is the Sagittarius sign, with the bow replaced by the shape of Lil Hal's "body".
