What're you guy's theories about the Lulusia eraser beam weapon?
Seems it doesn't disintegrate the affected area, but rather puts up a barrier like thing in the hole it creates. And probably teleports the targeted area.
If it merely disintegrated the target, obviously the hole wouldn't be there for but a super short time. It would fill up with water.
And it's implied that the water levels rising around the world is a direct consequence of this weapon use. If it disintegrated the island and the water around it all the way to the bottom, the water levels should be decreasing.
But since it increased, I think that what the weapon does is, teleport/erase the target, and then replace it with an invisible barrier that holds the shape of a gigantic hole in the middle of the ocean.
So, we might actually get to see Lulusia back someday. And whatever was inside Enies lobby too, as well as any other usage of that weapon we don't know of.
