I've heard people say that their Dragon Zombies cast Pandora's Box regularly, but I wonder if the central pit ones behave differently then the ones on the right path. I've never verified it though.

If it's not a glitch, then did the game designers intend for only the first Dragon Zombie to know Pandora's Box? That would be pretty sadistic of them.

In a way the first Dragon Zombie acts like a boss and the others act like regular random encounters.

On a different note, hold off taking on the boss Goda in Wutai until you get the Highwind if you want Trine on all four E-skill materia. You can take on the Da-Chao subquest without affecting the pagoda battles though.
