What kind of "Mk.V Armor" are you talking about? Mjolnir? Or some other obscure science-fiction thing I've never heard of? Also if it is Mjolnir, Nathan Fillion would be dead automatically. Normal humans literally cannot operate Mjolnir Powered Armor without the suit breaking every bone in their body, pulverizing and liquefying organs, and making one hell of a scene. Not to mention, even if he could operate it, it's more likely for him to wrench your own armor's arm back, breaking your arm in the process and causing you to crash the x-wing in this scenario. Fallout power armor is good, don't get me wrong, but it's not "casually flip several tonnes" good.
