Limits of unique and creative use of moves

[Reece]

So out of a thought experiment I decided to calculate how much force/weight Ururu's clawed gloves can exert (4,422.7 pounds of force per claw, calculated based on the mass of tungsten involved, and the average speed of a bullet). This made me think that Ururu could use the recoil to the advantage in very specific situations when she's not bracing against the force or in mid-air.

In addition to what's been said already, I figured I should just bring up one point: your calculation is off.

Sure, in reality, given the right mass and velocity, it might be possible to propel the claws of her gloves with approximately two metric tonnes of force behind each of them... but not in the Omniverse. If you read the rules thoroughly then you'll notice that the strength of moves is decided based on "Omniphysics", and Omniphysics is based on advantages & disadvantages.

Heavy weapons (such as the Buster Sword listed in the example moves section) are allowed to hit harder because they move more slowly than lighter blades such as katanas. Speed is an advantage, and so reduces the damage you can inflict, rather than increasing it.

Also, Ururu has 2 ATK, and two tonnes of force is way more than necessary to break concrete, which requires at least 4 ATK, so you should probably take into account that that will also reduce the force she can muster.
