Welcome to the chaos (Young Justice Season 1 Crossover)

Before Vash and Wolfwood left planet Gunsmoke, they discovered that it was biologically possible to have a kid, just in a way that's different than normal. Upon waking up after a particularly steamy night, they discovered a giant flower bud between the two. After a few minutes of freaking out, they investigated further, discovering that it was more than just a flower bud; it was an egg, or at least worked like one. Blame Vash's alien biology. After leaving planet Gunsmoke, the three got hit by a stray asteroid, causing them to crash land on the outskirts of Gotham, in its desert. While entering Earth's atmosphere, some of the Alien plants fell out of the ship, landing across the globe, a total of 10 out of the 500. Over time, Vash and Wolfwood fixed the ship up and buried it in the sand, building a house and an orphanage on top of it, with access to the ship via the house's "basement". After receiving information on the whereabouts of two plants located in Gotham, Wolfwood went to the location of the first plant, sending his accomplices to the second location. One thing he failed to realize was a shadowy figure following him from the rooftops above.
