Haiker N (ハイカーＮ,Haikā N?) is an enemy from Mega Man 10 that appears in Pump Man's stage. They can attach themselves between two pipes and spit the liquid flowing through them. In Easy Mode, it just spits liquid straight ahead at close range. In Medium difficulty, it spits a glob in an arc and in Hard Mode, it launches three of them.
Haiker N's name is probably derived from the Japanese word "haikan", which means piping.
