Heheh..."Damn you for being so badass!"
I liked most of the jokes in it, and I also liked your art style. The one criticism that I have on it, though, is it looks like Samurai Charlie's mouth is apart of it's nose, and a friend pointed out that if you weren't paying attention, it kinda looks like he's crying a huge drop of blood.
On another note, the music could've been better. Now, don't get me wrong, I'm very open for opinions when it comes to music...that's how Dream Theater got to be my favorite band of all time...And I have not heard of John Zorn before, and from your flash, his work sounds very mellow and peaceful, which is nice...but I'm saying that you could've used something that went more with the flash. That's all.
On another note, I didn't understand why Charlie had a gun, a sword, AND mystical chi powers...I mean, A sword and a gun I can deal with, (Cowboy Bebop's "Vicious") and Mystical Chi powers and a sword I can deal with, (DBZ's Trunks ( the only character I ever liked besides the really early kinda evil Piccilo) but ALL of them in one package? Don't you think he's a bit overpowered? He's gotta have his flaws, otherwise it makes for an uninteresting hero.
Other than these, this was a great flash, and because of it's unique art qualities and funny content, your chances are high in getting in the Weekly User's Pick or even home-page. Nice going, voting 5, Peace Out!
