YJ Fanfiction: Revelations pt 2

In walked Wally and Artemis. “So if Zatarra’s our babysitter for the week, why’s he still here?” Wally asked referring to Capt. Marvel “And why’s he eating my snacks?”
“That should do it” Sparx closed the panel just as the zeta tube revved to life.
“And just in time too.” added Breeze.
Recognized Batman 02
“Computer, national news” Batman got right down to business as the reporter Cat Grant began speaking.
“The initial attack was short lived but Metropolis was only granted a short reprieve.” The screen showed video footage of giant plants attacking Metropolis, tearing down buildings and the JLA swooping in to save civilians and fight off the vicious flora. “And despite the intervention of Superman and the Justice League, there seems to be no end in sight.”
“Should we get out there?” Robin asked eagerly as both Breeze and Sparx came over curiously.
“No.” Batman responded “The League will soon have the situation under control, that’s not why I’m here. According to your intel Sportsmaster supplied Cadmus Blockbuster formula to Cobra.”
“Who combined  it with Bane’s venom to create Cobra venom.” said Wally.
“Which the Brain used to create his animal army.” added Robin.
“And upgrade Wolf” Conner noted as he and Breeze patted the canine.
“The brain also used inhibitor collars.” put in Sparx.
“Like the ones used at Belle Reve Penitentiary.” said M’gann.
“Batman, is it possible these plant thingys are Cobra venom too?” Artemis asked.
“I had Green Lantern run a spawn analysis” Batman responded bringing up another computer screen hologram. “The vines cellulous does contain trace amounts of a Cobra Venom variant.”
“These cannot be coincidences” Aqualad stated. “Unrelated criminals cooperating with one another world wide.”
“Exactly” affirmed Batman “It’s now clear our enemies have formed some secret society of super villains. The attack on Metropolis is only the beginning.”
“Got that right” said Robin typing away on the computer he had brought up, setting up displays of other places that have been attacked. “The plant creatures have sprouted in Gotham City, Paris, Star City, Taipei-“ suddenly the screens went static.  
“Dude” Wally asked.
“It’s not me!” Robin insisted typing away “Someone’s cutting the satellite signal. All satellite signals!”
Then the gruesome face of a psychotic clown appeared on the screens. He tapped on the glass “Ladies and Gentlemen” the Joker smiled “We interrupt your regularly scheduled mayhem to bring you this-“ Joker whipped out a pocket knife “important announcement.” He turned the camera towards a group of notorious villains whom he called the Injustice League.
