The original General Zod didn't need a Prometheus space mask and batman armor, all he needed to take over the world was a black pirate shirt.
On a separate note;
I think the counsel must re evaluate Jor-el in this matter. He has been stated by the accused to disagree with the counsel before; this is evidence of conspiracy. The fact that he didnt destroy them when he had the chance, supposedly banishing them only preserved them so that one day they could be released again is proof of this collusion.
