Approved Submission Resubmit: Origin M3 Gekido Mecha

A resubmission of the old Gekido Mecha to replace the version removed by its previous author. I used the old version of the article as a template, so the template URL goes to a non-existent page. This page has been reworded as well as had its DR updated to DRv3. Some of the linked lists contain links to unapproved accessories and weapons that I am also working on re-doing, and will be submitting individually as I finish them.
