For a long time I have supported the idea that "Bionicle" is short for "Biological Chronicle". But then one day my science teacher began a lecture on her titanium femur. She refered to it as bionic. The kid sitting next to me is not a Bionicle fan, but he muttered "Bionicle" (perhaps making the connection in his head) and suddenly I understood.
bi·on·ic (b-nk) adj.
1. Of or relating to bionics.
2. Having anatomical structures or physiological processes that are replaced or enhanced by electronic or mechanical components.
3. Having extraordinary strength, powers, or capabilities; superhuman.
I no longer support the theory of "Biological Chronicle". The word "Bionicle" was created by LEGO as a noun describing a totally bionic creature such as the Toa or the Matoran.
The characters in this story line are bionic, and that is why the story is called Bionicle.
Feel free to contradict me! I'm open to suggestions!
