Gargoyles - Avalon, Part One Season 2 Episode 21
A mysterious man in armor arrives on the lakeside of Belvedere Castle in Central Park. As he walks into the city, he is attacked by the local thugs. It's clear that he's a better fighter than the three of them are, and easily beats them. However, Police Officer Morgan decides to take him in . . . telling him he can't be using a sword like that in the city.
It isn't until later when Elisa hears of this man from Morgan, and that he's looking for a gargoyle. Not just any gargoyle . . . he's looking for Goliath, and Elisa's shocked to hear that he knows the clan leader's name.
Arranging a meeting near Belvedere Castle, Goliath, Elisa, and Bronx meet the old man. The moment the man spots Goliath, he is overwhelmed with joy. As it turns out, he's the young boy Tom from the night of the Wyvern Massacre . . . and he's come to find Goliath for help.
For as it turns out, the Archmage is somehow alive and the eggs from Wyvern are in danger. Jumping on a skiff, Tom tells him his long and strange tale from the year 996 onward to Goliath & Elisa . . . .
