DarkLordKiller is a Thai third-generation Unterganger who started making Downfall parodies in December 2014. He is known for making parodies that involve either video games such as Medal of Honor, Sniper Elite, Kantai Collection, and Undertale, not to mention anime shows such as Kantai Collection's own anime adaptation and Izetta: The Last Witch. The latter anime series served as the main subject of his story-based parody, Hitler and the Last Witch.
