Hippogryph
From the Castlevania Wiki, the Castlevania wiki
A medieval mythical creature, the Hippogryph is closely related to the Gryphon, or Griffin. In popular culture, Hippogryphs are now recognized for appearing in the Harry Potter series of books. The Hippogryph is a mythological animal that is born from the crossing between a Griffin and a mare. Their head, wings, chest and front legs are like those of an eagle, inherited characteristic of the father, and the rest of the body is like the one of a horse, like the mother. The Hippogryph has a harmonic body, like the one of the winged horse or the Pegaso. A symbol of the impossible thing is considered to the Hippogryph, since the Griffin used to imagine quite often like animal that detested the horses, hunting them and killing them.
There is one Hippogryph in Castlevania: Symphony of the Night, appearing as a boss in the Royal Chapel. It has three methods of attack, which it is slow to perform. The Hippogryph can fly around the room, occasionally stopping to divebomb Alucard, it can draw in energy in order to spit it back out as a jet of flame, or it can lay eggs, which hatch into little baby Hippogryphs. It is one of the easier bosses to kill.
Hippogryph appears in Castlevania: Aria of Sorrow and Castlevania: Dawn of Sorrow as a collectible soul in the game. In Aria of Sorrow, it is found in a hidden room inside the Castle Keep area. In Dawn of Sorrow, it is found in the first sandy room of The Abyss. It is an ability soul that allows Soma Cruz to do a super jump by pressing up and the L buttons on the ground, or by pressing the L button in midair. In Aria of Sorrow, if you hit the ceiling, Soma will flinch in a comical fashion, while in Dawn of Sorrow, he will stick to the ceiling for a second before falling again.
