Spark Shock

Spark Shock (スパークショック) is Spark Man's special weapon. This weapon basically shoots sparks, as the name implies. Some enemies merely get paralyzed when hit, but a few enemies like Magnet Man can be damaged by this weapon. It's downside is only two enemies can be stunned at a time and you cannot change your weapon while there's one stunned.

However, they changed this in Mega Man III, allowing you to stun enemies and still being able to switch weapons. In some cases, this comes very handy when dealing with Shield Attackers and Jumbigs.

Other media
Mega Man uses the Spark Shock and Gyro Attack at the same time in episode 8 of the Mega Man animated series. When obtaining the weapon, an electrode can be seen in its design, probably for firing the sparks.

It also appears in Mega Man Megamix, but it is not used by either Spark Man or Mega Man, but Dark Man 3. It states in his profile that the attack he uses is actually a Spark Shock, which is probably true, considering their similar appearance and effect.
