I'm surprised that Power Ranger YELLOW likes this, and I thought he/she hated parodies. Other than that, I am a big fan of Fist of the North Star and you did an above-average job at spoofing it. However, you need to set your voices to stream, learn to loop your background music, and work on the animation some more if you decide to do more of this.
What I like:
-Finally, a Fist of the North Star parody
-Reminiscent of old flash back in 2000-2001.
What I don't like:
-Voices went out of sync.
-Music wasn't looped properly
-Needs more sound effects
Overall: In spite of its flaws, this is getting a nine from this HNK fan.
