In a not so distant future, Marth Icescape works as a nurse in a mental ward. The problem is: it crased down. Trying to save a few patients instead of running for his life, Marth lost almost his entire left side. unfortunately for him, even if you work in an hospital, they won't fix you better then your insurance allows it. And The Ward's insurance is very lousy. So they had to get some second hand parts and Marty had to go through heavy work to be able to use his new arm and legs. Then with a body and tools like that, they sent him to the "danger zone", where the heaviest cases are. After three years there, they moved him to a calmer department before he lost his sanity.

Also, note that Marth doesn't mind the new parts. As a technophile, he found himself sexier that way...
