Spoilers follow for Worlds’ Finest #19.
We know that Earth 2’s Supergirl and Robin are stuck on the New 52’s Prime Earth as Power Girl and Huntress respectively.
On Earth 2, Huntress’ father is the deceased original Batman and Supergirl is the cousin of the returned from the dead evil Earth 2 Superman.
Well, starting in Batman / Superman #8 we get the first cross-over between these two DC Comics New 52 series called First Contact. Power Girl meets Superman and Huntress meets Batman (but these super-heroines respectively met Supergirl and the Damian Wayne Robin months ago).
In Worlds’ Finest #19, which serves as a prelude to the First Contact arc, Huntress breaks into Wayne Manor – with some assistance from “our” Batman. It is an interesting first meeting as the cliffhanger illustrates.
Thanks for reading. All feedback welcome. :)
