Rolling Shield

Rolling Shield (ローリングシールド) is the weapon that X obtains from defeating Armored Armadillo in Mega Man X. It fires a blue sphere of energy that rolls along the terrain and bounces off walls. When charged, it creates a shield around X which can destroy minor enemies. The shield will remain active until it hits an enemy with over three hit points. This weapon is Launch Octopus' and Vile's weakness and is the weapon of choice against Sigma's final form.
