I've always thought that Blade was a pretty good character, but sadly created in a situation that ensured that he would never be accepted by fans. If Blade had been part of the cartoon, I think he would've been rather popular, but the decision to create him for the third movie in place of using an established character automatically made him hated by legions of young MOTU fans.
I got the figure as a kid and I liked it a lot. I also liked having a more human character on the villains side. It was also cool to have a guy who used two swords. I give him an 8.
