Appearing Block

Yoku Block, also known as Shutsugen Block (出現ブロック), Disappearing Block and Disappearing Tile, is a recurring obstacle in various Mega Man games, notably Mega Man Classic series. Yoku Blocks are temporary platforms which can be stood on a limited time. Groups of them form block patterns which often require memorization to pass and are considered some of the hardest obstacles required to pass without special items or Rush.
