Raging Raven

Raging Raven is a member of the The Beauty and the Beast Unit featured in Metal Gear Solid 4: Guns of the Patriots. She, along with the other members suffer from Post Traumatic Stress Disorder.

Early Years
Drebin tells Raging Raven's story over the radio to Snake after he had defeated her:

Born in Aceh, a place that had already seen years of war, she was captured as a young child by soldiers (whether they were rebels or with the government, it was unknown) and was kept in cages along with many other captured children. These soldiers beat the children every day due to all of the rage that they had built up by seeing years of war. The kids help on to hope and tried to cheer each other up by reassuring one another that help would soon come, all the while barely clinging to life by eating what little scraps of food there were, but soldiers would call them parasites and shit-eating ravens and beat them harder. Eventually, the soldiers left for an unknown reason, leaving the surviving,weak and helpless children to get eaten alive by the birds. The ravens picked apart the children one at a time but when they came for her, they instead somehow managed to cut her bonds and she was freed. In that moment, she was filled with an uncontrollable rage that smothered her soul. She tore apart the ravens and then followed the soldiers. When she caught up with them, she waited until night and then killed all the soldiers and the civilians that they had captured, all the while screaming and cawing. To her, there was no difference.

That is why she screams "Rage!" all over the battlefield, it was what those soldiers had imparted on her.

Guns of the Patriots
By this time, she is about 20.

Abilities and Traits
One of the more agile members of the Beauty and the Beast Corps, Raging Raven is a meld of aerial superiority and emotional wreckage. As she flies around the battlefield, she continually calls out to her opponents, "Show me your rage," shortly before attacking them. Unfortunately for most, this is the last phrase they ever hear, because Raven has many ways to annihilate her targets. If her razor sharp wings don't slice through people, the grenade launcher she carries in her hands or the missiles strapped to her wings explosively wipe most people off the face of the earth.
