Why don't they make an episode where Zeta gets hunted by The Hunter (the famous game hunter who had his spine replaced, in case I remembered his name wrong)? The Hunter could be re-hired by the government to catch Zeta. The government did it before, why can't they do it again? Another crossover episode I think would be cool would be Brainiac trying to take over Zeta's body, to use him for his own nasty plans. By the way, whatever happened to Brainiac in the late Batman/Superman and Batman Beyond days? Nobody's mentioned him as a possible enemy on Justice League either. Surely that computer must be around -- as the Joker would say, he's "harder to kill than a cockroach on steroids."
