Aragami

An Aragami is a colony of hundreds of thousands of cells uniting under a cell core. These cells, called "Oracle Cells", are the only type of cell in an Aragami forming flesh, blood and bone all the same. Oracle cells have a devouring nature which caused them to spread and devour everything in their path. However, Oracle cells do not evolve like normal cells do; in fact, each Oracle cell in existence is exactly the same as it was before the outbreak.
Each Aragami has a "core", from which all the Oracle cells in the Aragami are controlled. The core is the command center over the entire colony while the individual groups of cells form working parts of the entity such as an eye, fang, or tail. So far there is no known way of truly killing one ( its not that you cant kill one it doesn't just stay dead) .Types that have been spotted so far ( this is a God Eater fan-alt)
