Junk Shield

Junk Shield (ジャンクシールド) is Junk Man's Special Weapon. It uses electromagnetism to summon large chunks of scrap metal, which orbit around the user for protection and can hit enemies multiple times, but disappearing as they hit objects. The junk can also be thrown off as projectiles in three random directions across the screen, each projectile discarded from the two others by 120°.

Dr. Light: Yes, but the spheres can only absorb so much damage before they are destroyed.

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 grayer. To further add to the confusion, in the Get Weapon screen for the Junk Shield, Mega Man is simply gray-and-white.
 * In addition to the above, with Freeze Cracker's, Junk Shield's official artwork are the two official art that don't respect their in-game colors.
 * Junk Shield is the only shield weapon that diminishes in attack power (that is, damage when thrown) as it takes damage.
