Force Maelstrom
From Wookieepedia, the Star Wars wiki.
Force Maelstrom was a devastating combination of the powers Protection Bubble, Telekinesis, and Force Lightning. First, the user would form a Force Bubble around their body, concealing and protecting them inside. Then, any loose objects/persons around the user would swirl around the bubble, through telekinesis. Finally, the user would devastate the objects by blasting them away, in a surge of Force Lightning. One such user was Galen Marek.
[edit] Behind the scenes
It was also an ability granted to a person with the Jedi profession in Star Wars Galaxies, where it was a cone of Force lightning generated around a Jedi that damaged all close by.
