(Hope it's all good! I made up the creature.
And I'm probably such a derp, but what is the technological limits including weapons?)
Name: Derek Ashan. Goes by Talon.
Age: 18
Gender: Male
Species: Dragon-eyrie. See other.
Job/Position: Guard on whichever team you want.
Personality: Derek is a dark guy. His history plays a big part in that. Most of the time he doesn't mind being around others, but if they mention something of his past it will irritate him to no end and he may snap. His anger helps him to be a good fighter. Often he likes to be by himself, especially when he's flying at night. It helps him relax. He absolutely loves being outside and is rather educated about it.
History: Derek lived on the edge of town with his parents in a house by the woods. When he was only a child, his father became a volatile drunkard. He began to abuse both Derek and his mother- Derek because he was a freak and his mother because she bore him. They were both almost killed multiple times. One night his father slashed his face and then managed to stab his right eye. After that Derek couldn't take it. He turned away from the world and began to get very angry. When he reached the age of 12, he finally did it. His father actually killed his mother before him. In a split second, Derek lunged forward and stabbed his father in the stomach, just enough to keep him down. He then proceeded to burn him to death. He burnt his whole house down and lived as a loner in he woods as his creature for a long time. When he heard of the expedition, he decided to take a chance with it.**
Looks:

He has shaggy red hair and bright blue eyes. He always wears a black eyepatch (on in every form) because his right eye is blinded. He often wears a leather collar-like necklace (that's also on in every form). His normal clothes are as they are in the picture- a maroon shirt, black fingerless gloves, dark gray pants and black boots. He keeps a dagger in his boot as all times and there are pointed metal spikes on the knuckles of his gloves.
Other:
He can shift in under a second. A dragon-eyrie is a mixture of an eyrie (body of a lion, head of an eagle, wings of an eagle), the neopet, and the movie version of Saphira (large dragon). His body is that of an eyrie without the mane (lion), 2 feet at the shoulders, and he has paws with silver claws and a silver beak lined with teeth. His wings (the 'spine' of the wing is strong and long and there are regular scales for a bit going down the wing. The wing itself is covered in feather-like scales), 8 feet across, and tail (it's a long and strong tail with small, triangular silver spikes going down it. It ends in a tuft of feather-like things), 3 feet long, are that of Saphira. His ears are supposed to be 'eagle like' but are more like wolf ears. His whole body is covered in black scales with silver, star-like speckles and his eyes are the same in this form as they are in his human one. His scales are rather tough and act like a shield, able to block badly-aimed sword blows and far-off bullets. However, well-aimed strikes, jabs or shots can harm him. He can also control purple fire.**Random side note- in order to become a dragon-eyrie, your parents have to only be carrying the gene. They don't have to have it in dominance. Thus, his parents were human carriers.
Derek crept silently along the ground, his boots barely making a sound as he stepped on the soft dirt. A few despairing rays of light percolated down from the canopy above, splotching the ground with golden speckles. The wind was non-existant and no sound filtered through the trees. As he came to a turn in the path, he stopped and instantly dropped to the ground behind a large boulder. There was something approaching and he didn't know what it was. He peered slowly around the rock and saw a group elves. There were rumors that a renegade band of elves had deviated from their people and turned to all manner of depravities. This was them. Derek had heard rumor by the Elfen leader that there was a reward for them, dead or alive. Derek wanted that reward. As they approached, he stepped out from the protection of the rock. The elves turned to him and grinned maliciously. "What's a little twig like yourself doing out here alone?" One aimed an arrow at his heart and let it go instantly, flying straight at him. It bounced off his skin. The elves looked on, dumbfounded, as he smirked in victory. "I heard that you guys are worth a lot. I'm a little low on money so you guys are my way out of that depression." Without warning, he leapt at them, shifting midair. He began to thwack them with his tail and nip at them. Eventually he knocked them all unconcious and picked them up, one in each claw, before flying towards the Elfen leader to claim his reward.
