Spiky (スパイキー) is a spiked wheel-like enemy in the Mega Man X series that rolls forward to hit enemies with its spikes. If it is hit by the player, it'll spin sideways (with respect to the player) and fall, eventually self-destructing. They appear in the opening stage, Armored Armadillo's stage and Chill Penguin's stages in Mega Man X and Mega Man Xtreme, and in Noah's Park, Metal Valley and Primrose in Mega Man X8.
In Mega Man X8 they have two varieties of movement: rolling forward (like Spiky) or jump horizontally (similar to Spiky Mk-II). When a jumping Spiky is powered up by a Bulbrite, they gain a extra vertical jump between their normal jumps. Sometimes a large-sized Spiky appear in the Intermission of Noah's Park.

Spiky Mk-II, unlike its older version, stays its current shape, and hops about in hopes of hitting X or Zero. It's in Split Mushroom and Grizzly Slash's stages.
