Imagine how amazing it must be watching your creations brought to life around you. You make these characters and creatures up in your mind and draw them, then decades later you get to sit in the middle of it and be surrounded by them. It must be insane.
I would love for Stan Lee to turn out to be some all powerful character like the watcher.
