They discover that two giant-sized children are the ones repsonsible for slinging the arrows through the warp.
Green Arrow and Speedy leave the scene and explore more of this strange new world. They eventually encounter an alien who calls himself Xeen Arrow. Like Ollie, Xeen Arrow professes to be a heroic adventurer, and even maintains his own Arrowcave. The three bowmen team-up to stop a group of alien criminals. Afterwards, Xeen leads them back towards the dimensional rift and helps them to return home.

- Black Phantom (Single appearance)
Synopsis for The Atom: "The Atomic Flea!"
This story is reprinted from The Atom #18.
Ray Palmer has been asked to assist in Project Spaceshot-N at a secret government lab, and is asked not to reveal the labs location to anyone. Along the way, Ray stops at a nearby amusement park when he hears a shot ring out. Changing into the Atom, the Mighty Mite goes to investigate and finds that crooks are attempting to rob the money earned at the carnival's arcade. Although the Atom manages to knock out all the crooks using his size and weight changing powers, he is also stunned in the fight and lands into the tank of a flea circus. He manages to avoid a nasty fall by shrinking himself down to the size approximate to the fleas inside the tank.
Stricken with amnesia, the Atom believes that he is also a flea, and unrecognized by anyone begins participating in the flea circus. Meanwhile, Jean Loring is about to go to the carnival with her friend Melissa but stop by Ray's lab to get him to join them. A spy working for an enemy country has taken Ray's place and answers the door. The spy politely declines Jean's offer to join them and resumes his "work" while Jean and Melissa check out the carnival.
While seeing the sights, Jean marvels at the flea circus and, her appearance manages to jar the real Ray's memories. They have also uncovered other memories as well: How when he was bombarding himself with Protonic Radiation to cure the issue of residual Time Pool energy effecting him, he was visited by a group of spies who take them to their hideout and use a hypnotic device to force Ray into telling them everything about Spaceshot-N and replace him with their spy, who plans on stealing the secrets and taking them back to their country. With their plot finalized, they used the same device to make Ray forget about the encounter.
Now finally remembering, the Atom rushes back to his lab where he catches his double taking photos of the Spaceshot-N plans and decides to hitch a ride within the spy's camera. When the spy returns to base. There the Atom springs into action, using his size changing powers to trip up the spies with relative ease and turns them over to the authorities.
Later, back at his lab, Ray Palmer reviews the whole scenario and realizes that he had bombarded himself with too much Protonic Radiation, causing the earlier black-out and amnesia. As another side effect, it also caused him to briefly influence others into believing what he did, thus why everyone who saw him in the flea circus thought he was just another flea. He sums up his adventure by going out to dinner with Jean and Melissa and is amused when Jean talks about the amazing flea circus act that she saw.
