[@Letter Bee] I'm not up on this setting's alt-history, but I have a character concept: a sort of Soviet style socialist Arms master, who has been given an Artificial Noble Arm by the Paragons of Science because they found themselves in ideological alignment.

Since they're constructing Arms, would it be possible for them to resemble weapons that are more "modern" than normal Arms? My first concept is for an Arm themed after nuclear weapons? Not out of a desire to nuke anyone, but as part of a Cold War/Red Scare kind of theme. I'm thinking, again, it wouldn't literally be a nuke, but maybe some kind of heat/light/radiation cannon. I'm strongly tempted to give it nebulous 50s-themed powers, like making insects gigantic or something.
