Poor, poor James.
That was mean of me. But in all honesty, while writing that I completely and totally forgot about him. Which...is more insulting than any kind of rant I could produce.
He's not a bad Piccolo, the Piccolo they create is just plain bad.
But it's like some sort of ninja bad that slowly sneaks up on you because for all interested parties, he does provide quite an entrance as he blows up an entire village with a ki blast in a very Daimao-like scene.
And you think, "Wow! This could be a good thing!"
But then, they kind of forget that he's in the movie. We mostly see his unexplained avatar Mai running from place to place doing his bidding.
Occassionally he walks around being spooky and says a few words.
From time to time he has his blood drawn to create unexplained mutants.
And in the end he has a couple lines talking about the dominion he holds over Oozaru.
Despite the rather clever intro he's about as fleshed out as a Hercules or Xena villain.
