Nitro Man

Nitro Man (ニトロマン) is a Robot Master from Mega Man 10. He can transform into a motorcycle and release several Wheel Cutters.

He is a stunt robot who has appeared in many movies and TV shows. He is willing to do whatever stunts he is asked regardless of the risks. Nitro Man is also the president of a robot stunt club which has 60 members.

Strategy
Nitro Man rides around in his bike mode and tries to ram into you. Afterwards, he will perform a wheelie and ride up the wall and change back or jump up and fire Wheel Cutter. He will occasionally fire Wheel Cutter while on the ground.

On Easy Mode, he only throws one Wheel Cutter at a time and never performs wheelies.

On Hard Mode, his bike mode is ridiculously fast and he tends to run around on a short path again and again instead of across the room.

Chill Spike works best as the spikes will damage him when he rides into them and can be frozen if hit by it while firing.

Trivia

 * Nitro Man is the third robot master with the ability to transform into a vehicle, after Turbo Man and Ground Man (the fourth if Galaxy Man's U.F.O. is counted as a vehicle, too).
 * Even though Nitro Man has a yellow light on his chest, it is white in sprite form because of palette limitations on sprites.
 * Nitro Man is the only Robot Master in Mega Man 10 to not enter the boss room in the normal fashion- that is, fall down from the ceiling. Instead, in his motorcycle form, he rides from the left of the screen, flying to the right, then landing and transforming into his humanoid form.
 * His stage music was featured in the first Mega Man 10 trailer.
 * Nitro Man has some visual similaties with the character Kamen Rider Accel, from Kamen Rider W series.
