The tension between Batman and Guy Gardner reaches the boiling point in the Giffen, DeMatteis, Maguire, and Gordon story in Justice League 5 (Sept 87). Great cover for this one.
The top of the story introduces an everyday small town, Stone Ridge, Vermont. It's nothing special, except that the Gray Man shows up there. Dr Fate is about to enter his tower in Salem when he becomes aware of this, and mystically transports himself there.
Jack Ryder has just finished another news report slagging the new Justice League when he gets a tip about Dr Fate showing up in the town, and figures it is worth checking out.
The Gray Man has already taken over the town. Not only that, but he has captured Dr Fate. We learn that he was part of a group of mystics who probed the secrets of the universe. He managed to ascend and face the Lords of Order. For this, he has been turned into the Gray Man, given eternal life, and the task of gathering up the dream essence left by the dead, channelling it to the Lords. He has always considered this a punishment, and decided to start keeping some of the dream essence himself, increasing his power to the level it is now at. He intends to spread his control over the world, gaining enough power to be able to challenge the Lords of Order themselves. Dr Fate is not able to move, but does manage to send a message to the League, alerting them to the situation.
But before the message arrives, there are more troubles brewing with the team, centring mostly on Guy Gardner. He and Batman argue, which leads to the cover moment, as the two prepare to fight.
Delightfully, it's not much of a fight. Batman takes Gardner down with a single punch to the face. Guy remains unconscious for the remainder of the tale. Blue Beetle and Mister Miracle were onhand to witness this, but Martian Manhunter and Black Canary enter just afterwards. I love how upset Canary is that she missed it. Oberon is also back with the team, and is the one to alert them to Dr Fate's mouth emerging from the computer screen, informing them about the situation in Stone Ridge.
Batman sends Captain Marvel ahead to check the situation out, rudely ordering him not to take action until the rest arrive. Captain Marvel has been consistently insulted by both Batman and Guy, and starts to snap back. After he leaves, Blue Beetle calls Batman down for the way he has been treating Marvel, and Marvel's thoughts along the way show how his negativity has affected the hero. Batman has made Captain Marvel doubt himself and his abilities, and whether he really belongs on the team. That's not good leadership.
The rest of the team arrive just outside of the town. There is no sign of Captain Marvel, but they do find Jack Ryder's van, and then the Creeper shows up. He adds even more silliness to the situation, to Batman's fury.
But as the tale ends, we see that something very bad is going down in Stone Ridge.
The story continues in the next issue.
