I was thinking about this after watching The Clone Wars and seeing how the poor Zillo Beast was killed, it took technology and nerve gas to stop it, lots of poison and weaponry to finally kill it too, the Republic was lucky that it was able to bring it down at all. But what would have happened if the Yuuzhan Vong had invaded Malastare during The Yuuzhan Vong War and accidentally awakened another Zillo Beast during their attacks and Vongforming of the planet? Then in its rage at being disturbed it destroys their buildings and structures and creatures and wrecks havoc on them. The Yuuzhan Vong have no technology and thus very few ways to stun such a beast at all, they only use living creatures like Grutchins and other living weapons and creatures, no blasters at all, although those Corral Skippers might do some damage to it but probably would only piss it off, makes you wonder how much of a living hell it would have been for the Yuuzhan Vong if they had invaded the planet and disturbed a Zillo Beast after taking control, basically being powerless to stop it and on top of that the local residents decide to rebel in the chaos of the beast and its rampage, using its path of destruction to liberate themselves. Would make a cool story for Invasion, then if they defeated it the Yuuzhan Vong just like Palpatine might want to clone the creature so that they can use it, implanted with surge corral implants and improved with Yuuzhan Vong creatures being crossbred with it, a creature like the Zillo Beast seems to only be able to be killed with technology and the Yuuzhan Vong dont have this advantage at all, nothing they have could stop it, just piss it off even more.
