With the Justice League team transported to Rann the comic explains how the Ultra Project, meant to bring a group of constantly warring worlds together in peace, has been usurped by a madman who plans to use the product of the genetic experimentation and transform it into the ultimate weapon.
Introducing Supergirl to the team for the first time (but making no effort to explain why she’s not wearing a Red Lantern ring as she has been in her own comic for the past several months), Justice League United #2 gives us the still-not-quite fully-assembled team with more of the Green Arrow and Animal Man banter that so far has been one of its biggest strengths. With Supergirl’s arrival I’m hoping writer Jeff Lemire has plans to develop strong dynamic between the two younger female members as well as Kara may finally find the friend she’s been seeking in Stargirl.
The genetic plot is pretty goofy, but I’m willing to let this opening arc play out and see if Lemire and artist Mike McKone can make it work. Worth a look.
