Okay, so after seeing KA's thread about his newly acquired Mugenbine, my curiousity has grown. I've seen these at a local toy shop in SF about a year ago but didn't know what they were. Now I'm actually thinking about getting into this line thanks to Gen. Magnus. So what's the story behind these? Why are they associated with the alphabet? I saw on one site that Gen. Magnus sent me where it listed A-Z. Some of them had the letters on the side of their heads but others didn't. Is there an anime from this line? What's the average cost of one? I've seen anything from $8 to $20 for one.
