Before you say anything. yes i got this idea from EDICARTS.
About this creation
after Makuta Ugarax created his matoran body. he decided that he needed some help because of his bodies limitations. thats when he came across a skirmix (strangely enough there where Skirmix's on the new world) and used his mask of inner evils to transform the skirmix into a creature hellbent on destroying anything it was told to.
after some time Makuta Ugarax changed him even further by replacing his rapter hands with machine guns and chopping off the end of his tail to put a high powered rifle on the end. thats when Skarmax started to talk (not very well, he sounded like a caveman) and gave himself the name "Skarmax".
