Force Shockwave, also known as Focus Shockwave or Force Bomb, was a Force power that allowed a Force-user to emit a powerful destructive ring of energy, damaging or destroying anything in its radius.
The Jedi Master Obi-Wan Kenobi was a practitioner of this technique during the Clone Wars.
Savage Opress also released a similar massive Force pulse against large group of battle droids, eliminating all of them and knocking Anakin Skywalker and Kenobi aside.
