I have seen this japanese movie and it's showesd how somebody defeats emerald weapon in one minute or so. I can see that they use an item on barret and that barret goes ballistic and uses some attack over and over. Now here's the question:

Does anyone know wich item is used, and what attack barret is using??

It looks like a limit break but I know it's not cause I know know what al limit breaks look like, and if I could read japanese I would know but I'm sOrry I can't
