'''Metabolic cascade failure''' is a medical condition suffered by [[Flash cloning|flash cloned]] [[human]] beings.<ref name="ilb">'''[[Axon Clips Chapter 3]]''', ''[[Media:ILB_Your_fault.ogg|ILB_Your_fault.ogg]]''</ref> It is a series of neurological diseases that occur in short succession, typically rendering the human dead within the span of a year. Metabolic cascade failure is the eventual fate of the majority of flash clones, although a select few are projected to live a normal lifespan. Because human flash clones are grown a hundred times faster than natural-born humans (hence the name), many anomalies appear. The clones lack the [[Wikipedia:muscle memory|muscle memory]] and [[Wikipedia:socialization|socialization]] of their hosts. While these problems can be remedied with intensive therapy, compounding biological defects cannot be corrected. Rapid flash cloning of such immense volumes of tissue induces gross DNA base-pair errors; congenital defects increase 42 percent and incidents of [[Wikipedia:Parkinson's disease|Parkinson's]]-plus syndromes increase 67 percent. The average half-life of a human flash clone is 14.7 weeks in laboratory conditions.<ref>'''[[Dr. Halsey's personal journal]]''', ''September 8, 2511''</ref>

Most of the clones used to replace the [[SPARTAN-II]] children succumbed to this condition. Contrary to Dr. [[Catherine Halsey]]'s expectations, many of the clones lived far longer than previously estimated based on laboratory conditions,<ref>'''Dr. Halsey's personal journal''', ''December 24, 2517''</ref> with at least four surviving until [[2525]].<ref>'''Halo Legends''' - ''[[Homecoming]]''</ref>

==Trivia==
While the biological degeneration of the SPARTAN-II flash clones is described in multiple sources, the condition is only identified as "metabolic cascade failure" in ''[[i love bees]]''.
