Lightning Bolt

Lightning Bolt (ライトニングボルト) is Dynamo Man's Special Weapon in Mega Man & Bass. The user will hover in the air and summon a rain of powerful lightning bolts that cover the entire battlefield. This attack will hit every enemy and object in the area. During use, the player is momentarily invincible, allowing one to avoid enemy shots and some moving obstacles (such as the spike traps in Ground Man's stage). The Lightning Bolt can also be used to jump again in mid-air, similar to Astro Crush. This weapon is very effective against Cold Man and King. The weapon has perhaps the greatest aid against King Plane, since if the player is about to fall into a pit or a flying platform is destroyed by the plane's fists, it can be used to halt the fall and land on one of the platforms.

Capacity
Activating a Lightning Bolt uses five weapon energy units and releases four downward bolts of lightning in random areas. It can still be activated if less than 5 units of weapon energy remains. The user can activate the Lightning Bolt six times with a full energy gauge. 

Trivia

 * Along with the Time Stopper and Tornado Blow, Lightning Bolt is one of the few weapons where the player doesn't have enough energy in one stock to eliminate the boss that is weak to it (unless equipped with Energy Saver).
 * In Mega Man Powered Up, Elec Man has a new special attack on Normal and Hard Mode that is similar to Lightning Bolt, but he shouts "Thunder Bolt!" instead.
 * When you get the weapon and Mega Man/Bass gives you a demonstration, notice that there is only one "n" in the word "lightning" making it "Lightnig Bolt".
