OUR theory boy, stop trying to steal it <_<

I remember one of the producers saying that the theory that the monster was made by DHARMA to keep the people in the stations separate was "very interesting, but not quite right", or something to that effect. And on the blast wall map, it says that there was an incident (not necesarily THE incident) when "Cerberus" - the DHARMA's name for the monster - malfunctioned.

My theory is that the monster was designed to protect some underground experiment from being discovered - Cerberus guarding the "underworld".

Perhaps, even, this experiment is still going on...?

Of course, this doesn't explain either the monster's apparent ability to "sum people up", eg Locke and Eko, or the flashing images inside the smoke cloud.

Unless this is the way that the monster used to see if someone was authorised to be in a specific area - effectively reading their mind. But because of some "incident" this broke and it started attacking/not attacking people at random - causing DHARMA to construct the sonic fence...

Coming from the angle of science (which they said everything on the island had a grounding in) I think the monster is nano-technology.... though this is an extreme in terms of explanation

They already shot that one down. I like the idea of it being a DHARMA guard dog, but I think its just a DHARMA experiment. :P Not much more specific than that I'm afraid.

Perhaps its microscopic flying robot aliens spawned from 'Batteries Not Included' and desperate to break free from the cutesy image handed down by their spielberg associated forefathers. Or perhaps they are just misunderstood...

i think the monster is...wait for it...YER MA!
