Blocks are environmental units appearing in the Super Smash Bros. games that come in different colors, designs, sizes, and functions. Standard blocks act as unbreakable parts of the environment, while other blocks can be interacted with or broken. These unique blocks are listed below.
From the Mario series. Rotating Blocks are yellow with eyes. They rotate when hit, allowing players to go through them. They eventually stop rotating and can be hit again. They slow the knockback of characters flying into them, and can be teched on as well.
From the Mario series. Donut Blocks are yellow blocks with holes in the center that fall after a character or item lays on top of them briefly. After dropping, they reappear after a set amount of time.

From the Kirby series. Bomb Blocks explode and deal large amounts of damage and knockback when hit. The invincibility frames characters get from teching protect them from the explosions should they ever be knocked into one from below.
Original to Super Smash Bros., but analogous to Donut Blocks. After a character or item rests on it for a brief period of time, they shake and quickly plummet. Characters can wall cling on them without making them drop. When used on custom stages, drop blocks are able to fall right through characters and other platforms.
From Minecraft. These blocks can be broken by fighters jumping, attacking, and being knocked into them, though unlike Brick Blocks which are destroyed upon any impact, Minecraft Blocks can resist a certain amount of damage, which varies depending on the block's material. They can also be destroyed by Steve's mining, and produce materials for his use. While aesthetically similar to the blocks Steve can place, these blocks, as part of the stage, can exist indefinitely without player interference.
