From the preview:
o a break from the Grimm we've been previewing to look at new Heavy Metal. Meet M.O.D. the helpful Support Supreme. This little guy was originally designed as a war machine. But through accident or fate was spared destruction and reprogrammed to be helpful. Strangely enough it was Lady Cyburn who seemed taken with guy and the two spend a lot of time together. The relationship seems good for both of them.
Any ideas what M.O.D. could stand for? Tell us what you've got!
