Junk Shield

Junk Shield (ジャンクシールド) is Junk Man's special weapon. It uses electromagnetism to pull junk, which rotates around the user for protection and can hit enemies multiple times, the chunks of junk disappearing as they hit objects. The junk can also be throw off as projectiles in diagonal directions.

Trivia

 * Interestingly, the official art for Mega Man's colors when using Junk Shield (as shown in the image above) almost resembles his standard colors. When using the Junk Shield in the game however, Mega Man's colors are much greyer. To further add to the confusion, in the Get Weapon screen for the Junk Shield, Mega Man is simply grey-and-white.
