I actually think that an idea can't really show the stats, it more or less shows a concept. I believe that stats reinforce the idea that is the concept of a character. As an idea is the skin, the stats are the bones beneath. I mean you can't have a real character, be it PC or NPC, without a solid idea and concept. Just creating something, doesn't truly help, at least in my opinion. I really don't want to offend anyone, with me being new here and all. I'll just drop an example;
Tergus Kithkeras was born and raised like many githzerai, in a fortress monastery in the Plane of Limbo. Tergus Kithkeras grew into a great leader and fighter in the war against the illithids. Tergus has led many Rrakkma raiding parties; in each he destroyed many more illithids than other Rrakkma of the same size. Tergus was celebrated a hero after near a decade of successful Rrakkma.
A great illithid leader, Larkt, became driven with a new goal, the downfall of Tergus Kithkeras. He would bring him down after destroying his will to fight and then he would break his mind. First Larkt set forth his plan by secretly recruiting other gith from both sides through secret channels. His first goal was to turn Tergus’s friends and allies against him by making him look like a githyanki sympathizer. He planted a githyanki child and the doorstep of his wife, knowing she would hide the child and raise it. She did and after a year Tergus actually began to see this youth as a way to mend the bridge between the gith and maybe even bring peace to their broken people. His plan backfired when Larkt had the information leaked to several githzerai that had great hatred for the githyanki. Tergus Kithkeras was tried for treason for taking in the youth, his background saved his life, and Larkt knew this would happen. When Tergus was sentenced, the child would be executed, his wife would also be executed for treason and he would be exiled.
His heart broken and his life in shambles he was exiled, he was left in the underdark to die.
Tergus was heart broken and shattered, at his weakest he sat in the dark waiting for some creature to come and take his life. Instead, Larkt came to him and with promises of revenge for the death of his child and wife seduced him. Tergus Kithkeras submitted to his new master and became an enemy of his own people; before it was done one more tragedy would take place. Tergus changed his name to Gith’kirak -which means One who Kills Gith in his tongue- and undertook the ritual to become a half-illithid.
Gith’kirak now hunts his own kind, full of hatred for the death of his family. He has even come to discover Larkt was behind the whole thing but sees his illithid master as a savior, the one who opened his eyes to the evil of the gith, an evil more treacherous than what any illithid has ever done to him.

This posting as a character alone, doesn't do it justice at all, but leaving the stats out of it kind of feels empty. Together though, it feels much better, you can see how strong the character is, without spending a paragraph paraphrasing what he can do with his strength, you just look at the stat.
