Supergirl personally has the most to lose in Crisis On Infinite Earths. 1 / 6
There will be 3 Supermen, played by Brandon Routh, Tom Welling, and Tyler Hoechlin. 2 / 6
There are also two Lois Lanes, and Smallville's Lois looks just like Kara's mother Alura. 3 / 6
Supergirl has dealt with doppelgangers before, including in past Arrowvere crossovers. 4 / 6
But multiple versions of Supergirl's family and loved ones could die in the Crisis. 5 / 6
Supergirl could be permanently scarred by such losses, even if she survives the Crisis. 6 / 6
