Chapter 1: The Griffin (Hawkeye)

Before SHIELD was truly SHIELD they preformed an experiment which took the DNA of an eagle and the DNA of a lion and combined them. They created a creature of myth, a griffin. The griffin is chosen to become part of SHIELD but it has it's costs. Fury pairs him up with a new agent to see how he does. Clint Barton isn't sure how he'll adapt to having a creature that can kill him with one push but they become closer than either of them could either imagine.
In a different time a lion cub is taken from her mother and forced to live in a school for girls. She meets Natasha and they begin to train together. When they meet up with Clint and the griffin things happen. Budapest is a dangerous place and it is truly a survival of the fittest
