One of the magic arrows was dropped and activated, leaving GA and Speedy temporarily hypnotized. "Cougar" Cain and his gang stole the rest of the magic arrows and terrorized the town for days.

Oliver and Roy were taking a trip to Tokyo when their plane had engine trouble and crashed into the Pacific. The raft they got on did not have a paddle, and they drifted away from the other survivors. Soon afterwards, they washed up on an island inhabited by Japanese WWII holdouts thinking the war was still going on. Green Arrow was forced to cooperate with the Japanese, who believed they were scouts from the incoming war fleet (which appeared to be American ships on maneuvers).

World's Finest 98: The Unmasked Archers!
Oliver found bad news in the morning papers - he and Roy had been outed as Green Arrow and Speedy. They went on their last mission and confronted the commissioner - he thought Oliver and Roy were playing and told them he had business to attend. They picked up some other papers on their way home and realized what they'd seen earlier must have been a joke. Later, Oliver showed up in costume (without his mask) at a crime site. The commissioner laughed when his shots were way off. Speeding (hiding) was able to take down the crooks and show that Oliver couldn't be Green Arrow.

Adventure 256: Green Arrow's First Case
After seeing Starfish Island on TV, Oliver had a flashback and realized he and Roy had to get there to protect his secret identity. On the way, he related his origin to his ward. He'd fallen from a boat years before and swam to that very island. While away from civilization, he had to learn archery to survive. Trick arrows were created to make his catches easier. One day, he saw a ship anchored and swam to it - some of the crew were taking over the ship. Using his trick arrows, Oliver saved the ship from mutiny. He introduced himself to the captain as Green Arrow (he was wearing leaves as camouflage).
When GA and Speedy arrived, it was too late. The expedition was entering the cave in which he'd journaled his exploits years before. GA and Speedy shot trick Uranium arrows nearby, setting off their Geiger counters. The expedition left, not wanting to get radiated.

World's Finest 99: Crimes Under Glass
GA and Speedy were menaced by some crooks using lenses to commit their crimes. They'd used one to magnify the sun's rays to melt a safe, and escaped by using several on their helicopter to distort its image. Later, they used one to make themselves look like giants and rob an armored car. GA and Speedy shot the prism they were using with ink arrows so that it was useless. They were captured and the lens capers were through.
