Force Crush was possibly the darkest Force ability known to both the Sith and the Jedi. It was a more advanced form of the Force Grip ability. This ability lifted the opponent into the air, and as they were floating, their body literally imploded as it was crushed from within by the Force. Common among followers of the dark side, by 3,951 BBY many Force users could use the ability. The opposite Force power, which expanded and exploded a victim, was known as Force Expand.
