Tetsugen 28 looks awsome.
BTW if anybody is interested in the live action Tetsugen 28 movie (avail through netflix, 2008) avoid it like the plague. While the movie is only average what kills it are the subtitles. I've never seen a japanese film with such bad subtitling. You literally need a translator to understand the subtitles, and the timing is way off. It gets old really fast, borderline torture...they even manage to get black ox wrong calling him black bear.
