Dynamo

Dynamo is one of the bad-guys from the Megaman X series.

Story
Dynamo is a mercenary reploid, who holds no allegiances, but works for anyone who pays him. He is hired by Sigma to sabotage the controls of the Eurasia Space Colony, changing it's orbit into a collision route with Earth. Meanwhile, Sigma is purposefully destroyed by X and Zero, which spreads his Sigma Virus in the entire planet. The Maverick Hunters then starts running against the clock to stop the colony, collecting parts for the Enigma cannon. Dynamo interrupts them, and being a fine sportsman sends a message for X and Zero challenging them for a battle. His mission now was to disturb the Maverick Hunters. He holds back and just play with X and Zero to test their abilities, but he is obviously defeated. As the Enigma plan fails, they start a new plan to enhance a space shuttle to stop the colony, and Dynamo once again challenges them, this time fighting with all his power. He is once again defeated, fleeing before being destroyed by X and Zero and alerting them of their future.

Dynamo would be once again seen during the Nightmare Incident, this time working by himself. He was collecting nightmare souls to increase his own power, but he is defeated by X once again. He is never seen after this.

Personality
Dynamo is the all-around nice-guy who is just carrying his job. He is very careful and never risks his life too much, preferring to play easy.
