Vector Field.
Quirk: Vector Field.
Quirk Type: Emitter.
What It Does: Vector Field generates a bubble around the user, surrounding their body and makes the user able to manipulate the vectors in that small bubble, which is just like a foot away from his actual body when it's activated. The vector field itself simply manipulates the speed and direction of whatever incoming object as long as the user actually touches it. If the user can't touch it… the vector field still slows it down, but the user might have to get out of the way before it actually hits them.
Drawbacks: The user feels dizzy, and often heavily so. So dizzy it often feels as if they're gonna puke up everything. And the user gets intense migraines and brain strain as they use this Quirk.
Limitations: The user can't manipulate Vectors outside of this small bubble, and it's really not much vectors.
I do hope this is a grounded concept for Vector Manipulation.
