It it because all obstacles must be... REMOVED?

or is it because Cahdok and Gahdok are gone, and the Krana have gone mad?

Have they been mad all along?

The Bohrok are not just hurting the Matoran, they are hurting the envoronment! Was the "before-time" when there was nothing of value?

Are Cahdok and Gahdok working for Makuta? Is that why the Bohrok came only a day after Makuta's supposed defeat?

Are the Bohrok the good ones, trying to even out the imbalance after Makuta's alleged destruction?

And my final question: WHY HAVE THE BOHROK COME???

Uh, the Bohrok came right after Makuta's defeat in the online game. Makuta probably set them up as the next challenge for the Toa, therefore they are obviously bad. The krana are not mad after the defeat of Cahdok and Gahlok, Greg F says Bohrok parts will be used for something else....

yes lego nui you are right the borok parts will be used for something else the boxor because if you watch the movie on bionicle.com napuru takes a gahlok and makes the boxor

I knew about the Boxor already, but Greg F the comic writer of Bionicle, who is a member here said they will build something different with the Bohrok parts.

out with it what do they build? I really want to know. And I hope a good movie will come out soon.      

This sounds really stupid, but mabey they somehow build the toa and mask of light out of them

exo toa, boxor a.k.a. exo matoran, now exo turaga?

No, I meant tle last chapter on Bionicle.com. Do the Bohrok have to destroy the environment? And why?

... Maybe because when Makuta created them, the island of Mata Nui had no life on it.

Therefore, the Bohrok are 'programmed' to re-create such lifelessness.

i always thought of the bohrok as seperate from makuta.  the before time was probably long before even matanui and makuta even showed up.  they're trying to rip everything apart and turn it like when just the bahrag lived, nothing but chaos.

Because they are destructive by nature. Its pretty obvious... ;) And BTW I think Makuta placed the bohrok there knowing that if he was ever defeated the bohrok would run riot on Mata Nui until he could regain his strength!

The reason I think they are going on the war path is because, the bohrok goal has always been to return the island to the way it was before the Matorans.  As a result of the Bahrag being trapped, the orders to the Krana stopped.  Without specific instructions, the Krana only knew how to go about their main, original goal, bring the old Mata Nui back.  Instead of systematically changeing specific things, they are changing everything in their path, for Mata Nui was most likely a fairly barren place before the Matorans.  
I think the real question is, why are they trying to change it back?  Only the twins and the Krana are, at least, partially biological, so what is the big deal?  Well, we know that Makuta is not behind the next enemy, at least not like he was with the Rahi.  So, perhaps the reason is, the new enemy is what the Bohrok were preparing the Mata Nui for.  Inspite of the Toa's efforts, nothing has really changed.  The swarm is gone, but their goals and purpose live on! ( this is probably not true, because the Toa Nuva are supposed to play a part in Mata Nui's possible destruction )
