How to Create a Character from Scratch

In my opinion, characters are the most important aspect in a story. You don't have to agree with me, but just think of this: in the books that people seem to rave about (Harry Potter, Hunger Games etc) what is it that they reference most?
Not the plot.
Everyone remembers Ron Weasley (why didn't I say HP? Because, seriously, the clue's in the name) and Katniss. They are great characters, with personalities and goals. That's what drives a story.
Characters are also where a story can fall flat. You don't want to root for a cardboard cutout.

So, here's something to fill in to aid you in creating a unique character:
Name:
Age:
Internal Conflict:
What they will do about it:
External Conflict:
What they will do about it:
Enemy (ie the character's antagonist):
How they made this enemy and what they will do about it:
Hobby/skill:

Sometimes the answer will be short. Sometimes it won't. Whatever it takes for you to get a good understanding of your character.
Of course, this just gives you the basics. You won't have a full character quite yet. But this should be helpful for starting a story, plotting, and pin pointing the main things about your character.
