Goof: When Luthor grabs Gleek after he's playing on the control board, his green glove is missing. But in the next shot, his glove is present.
Goofs: When the senior SuperFriends return from their space mission, Superman is carrying the others in a yellow energy bubble. When they departed, Green Lantern had them inside a green energy bubble. And when Robin presents them with a shrunken Lex Luthor in a jar, his green glove is missing.
This is Green Lantern's only appearance in this series.
Luthor: The perfect operation and the perfect getaway. Sometimes, I even amaze myself!
