Described by Zeus himself as "A magnificent horse with the brain of a bird", Pegasus' behavior mixes elements of both a noble steed and bird-like behaviors such as his clicks and whistles and even perching on Hercules' shoulder at times.
Pegasus was created by Zeus using clouds as a gift for his newborn son, Hercules. That night, however, Hercules was kidnapped. Pegasus did not reunite with Hercules until the now-teenager, went to the Temple of Zeus. Zeus summoned a fully-grown Pegasus, while telling Hercules of their history. Zeus described him as: "A magnificent horse! With the brain of a bird...". Pegasus remained alongside Hercules throughout their adventures. He was not very fond of Megara at first, sometimes being openly hostile to her. When Hades plotted against Hercules, Pegasus was lured and captured by Pain and Panic, in the form of a female Pegasus. He was rescued by Meg, who convinced Pegasus to go find Phil. Pegasus became much more friendly towards Meg afterwards. Presumably, Pegasus remained alongside Hercules afterward.
Pegasus tagged along many of Hercules' adventures and acted as a mode of transportation. In Hercules and the Arabian Nights, Pegasus challenged Aladdin's Magic Carpet when Hercules and Aladdin battled. After they leanred they are apart of a shceme from both their enemies they team up while Pegasus and Carpet become good friends.
