Quicksilver

Quicksilver is an attack used by Jinx, the former master of the dojo in Monstro Town, in Super Mario RPG: Legend of the Seven Stars. It does a high amount of damage, so it is usually a one-hit-kill attack unless it is blocked. When used, Jinx zooms behind Mario, or another member of his party, and strikes with the sound of an explosion. This appears to be the Japanese version of the Chinese "tie shan kao" (贴山靠), a Bajiquan technique.
