I found Russian dubs of #metalocalypse on #invidious

The bad: its a dubover; it goes off-sync; and the original English audio can still be heard.
The good: I can tell which character the actor is portraying without the character being on screen, and the Russians also dubbed some of the songs.
At first I thought it was a pirate or fandub of the show, but the talent behind the voices indicates otherwise. Seems the translation team didn't get the script and had to transcribe the English audio. So Dr. Rockso's song was dubbed (understandable), but Nathan's songs are mostly unchanged. (They did however dub the opening lines for the Duncan Hills Coffee Jingle.)
I am trying to find if they dubbed Thunderhorse or Murmaider. But I think those clips just aren't on yewtube to begin with.
