Spike Ball

Spike Ball, also known as Spike Rope (スパイクロープ) in Japan, is the special Weapon that Mega Man X gains from defeating Axle the Red in Mega Man X5. In normal fire, X shoots out a green thorny ball of vines that goes a short distance, then returns to X. Charged up, X shoots out a purple spiked ball that ricochets across the screen four times (regardless of terrain) before leaving the screen.

This weapon is the primary weakness for Grizzly Slash and Sigma's final form. This weapon is also very useful in eliminating the Eagle Gs easily in the final stages of the game.

It seems, that in the prototype version of Mega Man X6, Spike Ball still exist as leftover data, which was replaced to Guard Shell during development. If the player charge the Guard Shell, X will shoot out bouncing black ellipse (which can be colored as uncharged Guard Shell if the player will press fire button while it on the screen), which strongly resembles charged version of Spike Ball.
