Scipio

Scipio (nicknamed Skippy) is Reyna's pegasus. It is nicknamed after the peanut butter brand, Skippy, because it is colored like peanut butter. Hazel is jealous of Reyna because the latter owns Scipio and is able to wear a spatha (the problem is solved when Hazel finds Arion).

The Son of Neptune
During Camp Jupiter's War Game, Reyna acts as referee for the game and flies around on Scipio so she can get a clear view of the Field of Mars. Later, Scipio aids Reyna in the battle between Polybotes' army and Camp Jupiter by attacking Polybotes from the air.
