Reality as is so often in the DCU has been changed with the cities of Gotham and Metropolis having been apparently fused. Superman and Batman notice of course and are attacked due to being unknowns here. After easily surviving an attack by Commissioner White and his police they meet...
...the Justice Titans!
Mash Ups are fun.
We find out in the issue their secret ID names are
Aquaborg: Arthur "Art" Stone Night Lantern: Hal Grayson. Donna Wonder: Diana Troy Hawkbeast: Gar Katar Flash: Wally Allen Star Canary's name is sadly not said in the issue.
The groups quickly reconcile and agree to work together and find out about Gothamopolis' mysterious recent killings.
But before that Superman and Batman meet one more interesting Justice Titan!
Terranado! I welcome our newest DCU gynoid.
Thankfully she isn't a traitor from what I can tell in this universe.
Next a fun scene little scene with Night Lantern and Batman.
Bats then says "I just realized how MUCH they have in common"
And the rest of the issue shows the mysterious killer in Gothamopolis being DoomStroke who's apparently working for Lex Joker.
