We'll Meet Again/YMMV


 * Complete Monster - There are several of these: Jose de San Martin, Napoleon Charles Bonaparte (the son of the one you know), Peter Cornelius, Jose Maria Torrijos etc, etc. Topped so far with Colonel Ricardo Goncalves.
 * Historical Hero Upgrade / Historical Villain Upgrade - Different people have different destinies, as a principle of good Alternate History. Noted example is Jose de San Martin; Liberator in our timeline, horrific monster in the Alternate timeline, although far, far more powerful.
 * Magnificent Bastard - -Edward Bismarck...very similar to the German we know and love in our timeline...only British, with the world at his fingertips, Maximilian Erhard and Sir Francis Tate.
 * Moral Event Horizon - Louis XVII when he starts shooting protesters who he believes threaten the war effort; San Martin when he shoots the Pope;
 * Nightmare Fuel - 'Case Study IV: Radiation Poisoning in the Public Domain'.
 * This Is Your Premise on Drugs - An alt-American Civil War...earlier...with a much bigger 'Confederate States of America'...and at the same time absorbed in a war involving a separatist Ireland and raving Classicists wanting to take over the world...and they're all allied.
