Very memorable episodes

I watched this cartoon on Saturday mornings.There were a few memorable episodes I remember on which I only saw one time and never saw again was were the Wonder Twins,First Storm and,Robin are left behind while the Justice League goes off the save some planet.While the League is away the junr members have to go up agiast Lex Luthor.I never saw that episode ever agian.The other was were Batman is still affraid of "Crime Alley" the place were his parents were killed.I only saw this episode in the mid 90's when the USA Network showed cartoons.Although the death of the Waynes were emplied,I thought that was a pretty gutsy move on Hana Barbara's part.
