Blocky

Blocky (ブロッキー) is a block stack with eyes. When damaged, a Blocky will throw the three blocks supporting his head at the player, causing the head to fall. He will, in turn, call three more blocks to him to support him, but upon being damaged a second time, he will be destroyed. In the English Normal mode, only one shot from the Mega Buster was required to kill Blocky. He appears in the stages of Metal Man, Crash Man, and Flash Man in Mega Man 2, Mega Man II and Mega Man: The Wily Wars.
