Lightning Bolt

Lightning Bolt (ライトニングボルト) is Dynamo Man's special weapon. The user will hover in the air and send down a rain of energy bolts in random spots. If the user himself is above an enemy, one of the bolts will hit. 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.

Capacity
Activating a Lightning Bolt uses five weapon energy units and releases four lightnings 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.
