So, in the Triva page, Storm Shadow is listed under Fake Nationality. I thought that they changed his nationality to Korean instead because of the actor playing him. So wouldn't it be some form of Race Lift instead?

Is there some trope to the effect of "weapons that were previously ineffective suddenly are"? Because it's notable that many of the same weapons with which the Joes attempt to stop the Neo-Vipers during the assault on the Pit to little effect, suddenly and without explanation are perfectly effective during the Joes' assault on the MARS undersea base.
