So I decided to put Bionicle and Rockraiders together and this is the result. Rockoh Glatorian of junk collecting.
So back story for this character goes as such.
Rockoh used to live on Bara Magna as a collector trying to find anything he could and learned to horde anything he did get. So when Mata Nui defeated Makuta and reformed Spherus Magan he went crazy with all the new junk from the Matoran Universe and starting collecting like crazy. He got anything from Rakshi armor, kanoka disk, zamor spheres which he refitted his thornax launcher to use and also a powerless kakama.
As you can see he has a lot of junk.
