Spark Man is a Robot Master from Mega Man 3 created by Dr. Wily and Dr. Light to charge electricity. Spark Man is designed to resemble a spark plug, and does not have hands. In place of them are two high-voltage electrodes, capable of producing powerful electric shocks and channeling his Special Weapon, the Spark Shock. This enables him to fire sparks of pure electrical energy in multiple directions, that can quickly immobilize opponents in their tracks.

Friendly to his comrades, he usually helps to charge them up when they need extra energy, and can generate twice as high voltage as Elec Man- however, he tends to be scatterbrained, and thus is not as good at focusing his power. He also has an unusual fascination with catfish and electric eels due to their unique ability to naturally produce electricity, but tends to get depressed when left alone for long periods of time.
