Animated World of DC Comics: Exploration Earth (All-New Super Friends Hour, 1977)
Aliens from the distant planet Zeno (or should that be Xeno?) invade Earth. Their attempt at "scientific study" is anything but, as far as the Super Friends are concerned. Scope out "Exploration Earth".
Looks to me like the Zenoian leader's designs might've been lifted from some similarly drawn aliens from Filmation's 1966-70 New Adventures of Superman, don't you think?
