Thank god they got rid of PK Cross. I still to this day have not figured out what it's used for.
Uh, PK Cross? I think you mean PK Flash. If you charge it up to the maximum, it's insanely powerful. However it leaves Ness stuck in place. It's best for edge-guarding, or certain places where an opponent must pass through it to reach Ness. Not good for much else.
Heh heh heh...I sense a good chance to be evil on Norfair. In Melee, if there was ever something of impending doom nearby (an Onett car, an Electrode), sometimes I enjoy just grabbing a person and forcing them to take the hit with me. This lava wave is gonna be a source of great hilarity for me.
