Spiky

Spiky (スパイキー) is a spiked wheel-like enemy in the Mega Man X series that rolls forward in an attempt to collide with the player.

If a Spiky's health is nearly depleted, it will spin sideways (with respect to the player) and fall over, eventually self-destructing. They appear in the opening stage, Armored Armadillo's stage and Chill Penguin's stage in Mega Man X and Mega Man Xtreme, the Sigma stages in Mega Man X and Mega Man Maverick Hunter X, and in Noah's Park, Metal Valley and Primrose in Mega Man X8.

In Mega Man X8, they have two varieties of movement: simply rolling forward or rolling while jumping horizontally (similar to Spiky Mk-II). When a jumping Spiky is powered-up by a MAME-Q, they gain an extra vertical jump between their normal jumps, plus a 1.5X speed increase. Sometimes an abnormally large Spiky will appear, along with regular-sized Spikys, in Noah's Park Intermission stage.
