The Story: "The Evil Connection!" by Gerry Conway, Dick Dillin, and Frank McLaughlin. Picking up from last issue, the Weaponers of Qward come to Earth and quickly encounter Green Lantern.
They blast Lantern and rescue Two-Face, and then tell them their plan to destroy the Earth and save the alien world of Dronndar. They ask Dent for his help, he flips his coin...tails!
Two-Face meets up with Superman and Aquaman, then Hawkman, Flash, and Atom, and places tiny power-blast devices on them. So, unbeknownst to them, when they thought they were fighting and defeating the invaders from Qward, they were actually siphoning off energy from Dronndar, doing their work for them!
Luckily the Atom figures out Two-Face's treachery, and tells Superman and Aquaman that the way to reverse the process is to let themselves get defeated by the Qwardians, which they do.
The the Qwardians stupidly piled on, blasting the heroes over and over, reversing the whole energy-transferring process, which burns out the transmitters Two-Face placed on them. Then it was short work defeating now-weakened Qwardians (confused yet?).
The issue ends with Two-Face back in Arkham Asylum, telling the story to another cell-mate:
Roll Call: Superman, Aquaman, Flash, Green Lantern, Hawkman
Notable Moments: I like how the Joker is about as chaotically insane as he's ever been--here he is, sort of wishing for the sweet embrace of death.
Thank God Two-Face decided to betray the League; otherwise they probably would've asked him to join!
