Deadly Bound[from internal data] (also referred to as Sprint[Japanese title]) is a recurring attack used by various bosses (typically ball-shaped "soul" bosses) which involves the user bouncing along the background before slamming hard into the ground, creating shockwaves on landing and usually dropping Drop Stars in its wake. The first user of this attack was Drawcia Soul in Kirby: Canvas Curse, and it has since been reused by several subsequent ball-shaped bosses in the Kirby series.
The following table outlines in chronological order which games this attack appears in, which entity can use the attack, and any other pertinent notes.
