Nitron[1] is an enemy first appearing in Mega Man 3. It is a blue or yellow robot with a circular design and various bulbs, the bottom of which can be used to drop exploding flame pellets as it flies overhead.
In Mega Man 3, Nitrons appear only in Gemini Man's stage (both the regular and Doc Robot version) and only in the first section, where they are paired with Bomber Pepes the first time around and Jamacys the second time. They fly in from the side at a certain height until they get close to Mega Man, then dip down in order to drop three pellets, with a certain distance between them. These pellets explode into flame pillars, similar to the ones created by Heat Man in Mega Man 2 or the Flame Blast weapon in Mega Man 6. After attacking, the Nitron flies straight up to escape.
Although Nitrons have only one hit point, they often spawn too high up to immediately be hit with the Mega Buster, but may lower themselves far enough to be destroyed while attacking. In the Doc Robot version of the stage, the Nitrons' blue and yellow colours are switched around and they create blue flames, though their behaviour is unchanged.
