Puck is one of the immortal Children Of Oberon and a minor villain from the animated series "Gargoyles" - though, somewhat ironically, he was not as antagonistic towards the group as his human alter-ego Owen Burnet.
In stark contrast to Owen Puck is a very mischievious being and has on occassion caused trouble, however he is not as malicious as some tricksters and actually has a certain fondness for humans: perhaps one of the traits that made him an enemy of the Manhattan Clan was his loyalty towards the Xanatos family, though this likely changed when David Xanatos seemingly redeemed himself.
