Let me copypaste what I wrote in an unrelated thread a few days ago:
Hitler's first Pokémon would have been a Smeargle, who sat by his side on the streets of Vienna, trying to help him sell his paintings. But as he delved into politics and became powerful, he forgot about his old friend. Smeargle watched him from the back of the Sportpalast as he delivered his speeches, growing ever sadder seeing what he had become. Now allowed into the bunker in Berlin after it had painted a copy of one of Hitler's early paintings over a propaganda poster, Smeargle was left to be raped by Red Army soldiers, and died of its injuries not long after the Führer committed suicide.
