The Story: "Crisis in the Thunderbolt Dimension!" by Roy Thomas, Gerry Conway, Chuck Patton, and Romeo Tanghal. We open in Keystone City, where the Flashes of both Earths are taking care of some particularly hapless crooks.
After wrapping them up and handing them off to the police, they head to the JLA Transporter Tube atop a local building.
While they're waiting for the tube to kick on, a giant pink lightning bolt comes out of suddenly-appearing storm clouds. Not only that, but it seems to headed right towards them!
The bolt seems to "push" Jay Garrick out of the way, but it zaps Barry Allen, knocking him out! Jay is shocked to see the lightning bolt is actually his fellow superhero, Johnny Thunder's Thunderbolt!
He tries to attack it, but T-Bolt blasts him, knocking him out for a moment. As he disappears into the sky, Jay sees that Barry is...dying!
Meanwhile, up at the JLA Satellite, the two sets of heroes are having a party. Except for Firestorm, who doesn't seem to be enjoying himself:
(By the way, coming in on Black Canary saying: "...oh, and it's about this long, and as wide around as a marking pen": is it just me?)
Anyway, Firestorm is mopey because Power Girl--who he has made a play for every time they reunited with the JLA since he met her--seems to be ignoring him. Elongated Man tries to cheer him up, but its Hourman who delivers the advice he wants to hear:
Hourman, mack daddy.
Suddenly the party is broken when the T-Bolt shows up at the satellite, and he blasts Firestorm as mercilessly as he did The Flash.
He then does the same to Zatanna and Elongated Man, but only barely touches the JSAers plus Black Canary and Red Tornado. In fact, it's Canary's Canary Cry that seems to drive him off.
Jay Garrick then shows up, with Barry is in arms, and they put all the comatose JLAers in Sick Bay. They then realize the only connection the rest of them have us they were all born (or, in Reddy's case, created) on Earth-2...but what could that have to do with anything?
They try and contact the other Leaguers, but they see a similar fate has befallen them:
...I always found this panel a tad unsettling, not seeing what happened. To be able to take out Superman and Wonder Woman before they even got the chance to get up? Wow!
While all this is happening, the JSA hears that a group of super-villains are attacking and robbing various places on the globe. The JSAers break up into teams to stop them, with Starman and Canary staying behind.
Starman has a hunch they might find out what's going on if they visit T-Bolt's home dimension, so using his Cosmic Rod, they go there, where they are sucker-zapped by the T-Bolt.
When they wake up, they are imprisoned by the T-Bolt, who is controlled by the evil, Earth-1 version of Johnny Thunder! Not only that, but he shows them something startling--encased in a glass coffin is her deceased husband, Larry Lance, plus...Black Canary herself! To be continued!
Roll Call: Flash, Green Lantern, Black Canary, Elongated Man, Red Tornado, Zatanna, Firestorm
Notable Moments: A rare Superman, Batman, or Wonder Woman-less JLA/JSA team-up. I guess with Batman out of the JLA, it made more sense to feature the other heroes.
A great, insanely-detailed cover by George Perez. The JLAers really look like they're in pain there.
