Be warned watching this is pointless without meeting some requirements: Part I-II you are not going to find very humorous without vaguely knowing or imagining you know edicate in 80's Japan. Don't think it parodies anything. Part III mostly parodies Ashita no Joe. Part IV is a kaiju plot parody of Gojira (Godzilla). You don't necessarily need to see the movies for some laughs. It seems to be loosely based on Terror of Mechagodzilla. Some looks like a sentai parody, I don't know which if any. I is the weakest and and IV is the best with everything in between fitting the line. Only Parts I-II are connected so youmay skip around if 7 minutes is too much for you.
