Blecker

Blecker (ブレッカー) is a block enemy in the Central Computer Stage in Mega Man X2 and Mega Man Xtreme. These will drop from the ceiling and fire energy blasts, if X triggers the security alarm by getting caught in the spotlight. One of them is right next to a gap in the ceiling, which you can climb up with an undropped Blecker, containing a Life Up. (Hint: Use a dash-jump and a charged Speed Burner.)
