Power Man and Afro Samurai

 My preference for a character's appearance is usually how I first encountered them, so I still have a great fondness for the classic chain belt and tiara look for Power Man.  That said, I can understand the need to update Luke Cage's appearance.  I'm glad Marvel at least still makes sure to usually put him in a yellow shirt, as a nod to the old days.

Seven Swordsmen

Back in another life, when I went to acting school, I took a fencing class, and it was an absolute blast.  There were a few offensive and defensive moves to learn, and once I had them down, it was easy to choreograph battles.  We would practice in slow motion until we got it perfect and then switch to real time.  Tons of fun!

Afro Samurai and Black Dynamite

A friend of mine loaned me the complete collection of Afro Samurai cartoons a few year back, and I wound up watching the entire run over the course of a weekend.  I loved the character design, over-the-top action sequences and the voice work by Samuel L. Jackson (in both of the lead roles, no less).  I definitely recommend it, especially to Manga fans.
