Martroid 98 is a German Unterganger who started making Downfall parodies since 30 September 2015. Prior to this, he has made a few Stalin parodies (which he continues to make to his day, along with Downfall parodies) and gaming videos.
He is also known as the developer of the fan game Hitler's Epic Adventure.
His parody, Hitler and Co. in Corpse Party, is considered to be one of the longest Downfall parodies ever made (not counting multi-part parodies), with a runtime of 48 minutes. It has also placed 16th in 2016's Hitler Rants Parodies Contest.
