While investigating the appearance of strange graffiti at sites all over Metropolis, the girls run across a second group of heroes looking into the matter as well. This team, the Invinci-Bros, consists of Aqualad, the Flash, Green Arrow, Green Lantern Hal Jordan, and Hawkman; their leader is Steve Trevor, on whom Wonder Woman still has a crush. The Bros and the girls race to reach the next expected site, but find the graffiti appearing by itself and acting as a signal to open a dimensional portal. Three evil Kryptonian prisoners emerge - Ursa, Non, and General Zod, who had been locked away by Supergirl's mother just before Krypton exploded. The villains overpower both teams and threaten to crush a bus filled with passengers unless Superman surrenders himself to them. Hal sends Steve off to get donuts, snapping Wonder Woman out of her crush and sparking her to organize an offensive. The heroes keep the villains distracted long enough to drain their powers with a chunk of kryptonite (retrieved from the museum by Bumblebee and Hawkman) and drive them back through the portal. Afterward, the Bros credit Steve with saving the day, since his departure allowed Wonder Woman to think straight - to the girls' annoyance.
