Embargo is Zoroark's Down Special Move in Super Smash Bros. Global Apocalypse. Zoroark covers herself with a dark barrier which reflect any projectile. It's function is very similar to Wolf's Reflector from Brawl, but not in sight. It can also deal damage if used on a nearby enemy. In the Pokemon games, Embargo was used on a different pokemon. Instead, here, Zoroark uses it on herself for protection.
