How about a Distort power where if the ragdoll or other physical objects are affected by this certain power it will distort the structure of the ragdoll or object causing it to disfigure and eventually break apart.
I was thinking of a power. Internal: It's a power which spawns a powder which when it collides with the ragdoll it will make it faint, temporarily, after a short period of time the ragdoll would start violently shaking before exploding into more powder to infect another thing.
