Hey, I posted the following kind of long description in the general discussion thread of how I think Zod's role on Krypton should be portrayed, and how it could be used to build up to sequels(particularly in regards to Brainiac). The problem is I posted it right before the new costume pic hit, so it's gonna get buried in the thread, so I figured I'd post it up here so others can read it and share their thoughts.....
I think it would be cool if Zod had something to do with Krypton's destruction. That would really piss off Supes.
"You destroyed Krypton...I WILL NOT LET YOU DESTROY EARTH!"
Meh. I actually prefer kind of the opposite. I really liked Geoff John's take on Zod, that he was actually an ally of Jor-El at first, since he beleived Jor-El's predictions of doom for Krypton. Then when the ruling council refused to listen, he attempted a violent overthrow of Krypton's government, which Jor-El thought was going too far. It gives some nice depth to Zod, giving him an honorable motivation, but extreme methods. It would also help to distance this version a little bit more from SII's Zod, who was just straight-up evil. I say save the role of having something to do with Krypton's destruction for Brainiac in a sequel. Portray him pretty much like in STAS, as the artificial intelligence system that pretty much runs Kryptons infrastructure, and influences the council to ignore Jor-El's warnings because he wants to save himself.
If they REALLY want a great build-up, then have Zod's storyline building up to Brainiac, and give Brainiac the origin of being an AI that wasn't created on Krypton but rather discovered by Kryptonians on a crashed space probe from elsewhere in the universe,
his true origins unknown to even Brainiac himself. They study Brainiac and then over the years, begin to trust and use him to help run Krypton, even though Brainiac himself is really using THEM. He simply wants to catalogue all their vast scientific knowledge and then leave them to be destroyed in Krypton's impending explosion, which he discovers early on. Jor-El also eventually discovers that the planet will explode from ancient internal pressures, and when he attempts to use Brainiac to help study the crisis, he finds that Brainiac has known of it for some time and has hidden it from the Council. Knowing that he is outmatched by Brainiac, this is when Jor-El recruits the help of General Zod, a colleague of his who is active in the advanced military science division. With the help of Zod's resources Jor-El begins to develop the Eradicator, his own sentient AI, that he intends to use like a computer virus to purge Brainiac from all Kryptonian systems. But before he can finish development, Zod grows tired of waiting and launches a full scale coup d'etat, attacking the capital city of Kandor. Brainiac uses this attack as a ruse, secretly miniaturising the entire city to keep as a specimen, claiming that it was atomized and framing Zod for it's destruction. Jor-El, horrified by what he believes Zod has done, and wanting to atone for what he sees as his own part in it, assists in the capture of Zod and his banishment to the Phantom Zone, thus earning Zod's eternal hatred. But of course by now, it is too late for Jor-El to do anything about the fate of Krypton. His Eradicator AI is not complete. He must now focus on outfitting the experimental star-drive he was developing onto a small escape craft for his infant son. Hours from Krypton's destruction, Jor-El activates the incomplete Eradicator in an attempt to prevent Brainiac from also escaping Krypton, but this is unsuccessful. Brainiac is able to upload himself to an escape craft and now knows about both the Eradicator and Jor-El's plan to save his son. Jor-El places his son into the small escape rocket, and uploads the Eradicator program onto a holographic device, sending it with Kal-El, so that he can one day learn of his origins. The rocket is sent hurtling into hyper-space towards the planet Earth and Brainiac,now in a grotesque, tentacled, bio-tech android body watches from orbit, recording the planet's destruction and vowing to track down the child someday and claim the secrets of the Eradicator for his own study.
And so Both Kal-El and Brainiac escape the death of Krypton. Kal-El grows up on Earth, raised by the Kents as their son Clark,eventually becoming Superman, and facing a freed General Zod and his Lieutenants, who he manages to defeat, but not before Zod is able to tell him more about his origins and the truth about Brainiac and what truly happened to Kandor. In his attempt to conquer Earth and recreate the glory of Krypton, Zod even used the Eradicator(which Jor-El DNA coded so that only he and Zod could operate) to create a fortress full of Kryptonian technology at the Arctic circle, which after his defeat Superman uses for his own. However, this now active Kryptonian tech has finally alerted the malevolent A.I. Brainiac as to Kal-El's whereabouts. Brainiac comes to Earth in a sequel and confronts Superman, demanding the Eradicator device. In the course of his clashes with Brainiac through the film, Superman is able to rescue the bottled city of Kandor, and it's only non-miniaturized resident, his own cousin Kara Zor-El, who Brainiac has kept in stasis all these years, attempting to use her genetic relation to Jor-El to bypass the Eradicator's DNA coding in case he ever found it. Superman eventually defeats Brainiac, but also over the course of the film, Brainiac reveals to Superman his true purpose.....Krypton is not the only world he has pillaged for knowledge.....he has done so many times for nearly a millennia. He tells Kal-El that he is simply following his original programming, to gather all scientific and technical knowledge from any advanced races he encounters, and then eliminating the holders of that knowledge. Brainiac does not even know WHO originally programmed him or WHERE he originated from, only that his programming requires him to continue to gather knowledge from the known universe until he either finds or is himself able to calculate a certain.......
EQUATION. Naturally, Brainiac's defeat by Superman does not go unnoticed.
And that's just off the top of my head....

t: So, whattaya think?
