heres a snippet from the Description in my draft. been working on it for about a week now and has a few kinks to work out.
Description: SCP-XXXX's Anomalous Property is its Cellular DNA. The Entity is a Parasitic Lifeform that is capable of Assimilating the Bio-Mass of other Fauna based Organisms, and altering its genetic structure into any previously memorized Biological traits of its choosing, or taking on the form of whatever Biologically based Organisms it can make physical contact with (The Entity Does not need to kill the Subject in order to Achieve this). It is practically Immortal, with constant Repair on the genetic level credit to its Anomalous nature, preventing aging. It has some level of control over various aspects of its Bio-Mass such as Weight, Hardness, Viscosity, and Temperature, however, the levels to which it can control these aspects are not as keen as its ability to actively manipulate the structure of DNA. When a portion of SCP-XXXX is removed from its mass, it deteriorates into carbon dust in approximately 0.02 milli-seconds per cubic centimeter, hense no data on SCP-XXXX's Gentic structure has been researched (besides inconsistent carbon dates, probably due to it accumulating new Bio-Mass constantly). A brief summery of some of the things SCP-XXXX can currently manipulate its Bio-Mass into can be read in Addendum XXXX-b. Every Cell in its body has the full functionality of a "brain" and each retains a copy all memories belonging to SCP-XXXX and possesses full processing power, however the individual cells cannot work together to increase brain capacity or power.
SCP-XXXX does "feed" in a sense, that sense being its Bio-Mass will slowly deteriorate, exponentially slowing, and stopping naturally just above 1kg (monitoring of the air in the containment chamber has showed that at this point, the airborne organisms present are enough to sustain it) and while reportedly being extremely uncomfortable for SCP-XXXX, no ill effects of this have been recorded.
What i need help on is length, science, grammar, story telling, and just if the idea is too un-original. note that in my drafts, theres about twice as much as this in the total description, talking about this entities character traits, but first i just want to get this milestone up to scratch. making the entity logical and feasible. thank you in advance for any help!
EDIT: it should be noted that this is not all the information about this entity, i have various amounts of testing logs and interviews either writen or planned that go into just how far its abilities span and the difficulties in containing it (for the most part, it is keter)
