I had forgotten how amazing he was as an evil mastermind until I recently began to re-watch the series on YouTube. He's definitely up there on my favorites list. Even when he loses, he wins! He's like an evil Tony Stark.
Did I mention that I just recently borrowed the first season of Gargoyles? And became obsessed all over again. I -heart- this show. And especially Xanatos. He was always my favorite villain. Not that this should be a surprise. Nice stamp!
