Appearing Block

Appearing Blocks (出現ブロック), also known as Yoku Blocks, Disappearing Blocks and Disappearing Tiles, are recurring obstacles in various Mega Man games, notably the original Mega Man series. Appearing Blocks are temporary platforms which appear and disappear is a specific pattern at a set interval (usually one second). The player can stand on them while they are solid. Groups of them form block patterns which often require memorization to pass and are considered some of the hardest obstacles required to pass without using special items or Rush.
