I recommend The Complete Idiot's guide to Writing Well.
You got structure errors all over the place, lack of capitalization, and punctuation issues.
It should look like this:
Specter X wrote:"So this is the great spirit hunter, hmm? Not as great as I thought!" roared the Emperor of Darkness, furious that his minions were killed off by humans.
But he had powers that revealed themselves as he dropped demon essence on the blood drop he was observing.
BOOM! The demon essence was scattered away from the tiny sample. "Interesting, that way, I can make sure I have an indestructible legacy, a human 'son' that fills in my place in the underworld soon."
He used ancient technology from the vast necrosis, his homeworld and his empire, to create a legacy, and by adding his own DNA, the process was a success!
Rising from the stasis chamber was a human boy with black hair and burning red eyes, the legacy of Specter. Specter named him Victor, on behalf of Frankenstein, the first man to create life.
We capitalize titles.
Use commas to separate elements in a series, add a little conjunction, set off introductory elements, and set off parenthetical elements. http://grammar.ccc.commnet.edu/grammar/commas.htm
You do not need a coma to follow every and.
Paragraphs are made by the separation of ideas. As soon as a new idea element is presented, a new paragraph is formed. For example, when Person A talks, they get their own paragraph until Person B talks. Actions can be included as well in those. Another example is this post. Note that every new idea is represented by a new paragraph, and made easy to read with spaces between paragraphs.
Avoid repetition. An example is your "dropped... drop" you have going in what is now the second paragraph. Expand your vocabulary by using a thesaurus.
Don't be afraid to get some meat on the bones of your story. You can expand events, describe backgrounds, thought progressions, and processes. Attempt to post your story by chapter or chapter sections instead of five lines of text. You can use things like Microsoft Word, Open Office, or Google Documents to create your story.
If you have over a hundred words, I'll be surprised. Good chapters and updates clock in the thousands range, and in my honest opinion, 3,000 to 6,000 is a good chapter.
All good stories start with a draft too (don't post it) that can be used as a flexible guide for the writer.
Also, if you need, get yourself an editor or a pre-reader to assist you with your writing.
