The "Yellow Stick" on the GCN controller. In SSBM, it can be used to perform any Smash Attack while standing, or any aerial while floating. Smash attacks performed with the C-stick are performed one frame slower than the fastest possible, which has little to no effect on its usefullness. The C-Stick can also sustitute for the control stick in some instances, as it can be used to roll or sidestep from your shield, direct the direction of a tech, and influence Directional influence.
