just a few questions about them..

1) exactly how are they attached to the EVA?
and do they look something like cylindrical spray-cans
sticking out of the EVA's back??

2) Does having so many of them sticking out of Lucifer's
back in any way increase his strength?

3) An unrelated question. Is it really coincidence that
Lucifer got named Lucifer by DJ?

Thanks.
