BBLshield 

The ultimate defense of the ROFLcopter. It can block the lethal attacks of both the LOLLerskater and the LMAOplane. Although it is the ultimate shield, it does have a limited use time.

"Right before the onslaught of lollerskaters, I had to activate my BBLshield to defend against them."

"My ROFLcopter got shot down after I ran out of energy for my BBLshield"
