Normal POV
BOOM!!!!! another giant steel door was blown of it's hinges the Avengers walked in and as Thor summoned his hammer from the smokey remains of the door the Avengers observed the H.Y.D.R.A. (I know Hydra wasn't discovered until a few years after the Avengers lets just roll with it) lab. Mainly they were focusing on a circular tank filled with water was were a (H/C) hair colored women was floating. The women was covered in light grey fur, large paws forming with claws ready. A long scaled alligator tail extended from her butt it thumped against the glass.
A long grey dorsal fin protruded from her back with gills hidden under her fur. Her muzzle extended and stretched with sharp teeth filling her mouth with some hanging out of her mouth from her upper and lower jaw. She stood taller than Thor but a little smaller(by a few inches)then the hulk, yet bulkier and tougher. Feline ears perched on the top of her head with slight white feathery tuffs surround them. Her belly was covered with soft white swan feathers. Suddenly H.Y.D.R.A. agents were opening fire obviously determined to keep the women in the tube.
Steve shouted out, "Form a circle around them and advance" Steve walked forward with his shield raised taking out any enemies that were near him. Clint and Natasha were taking cover behind a couple of stray metal crates, Clint was shooting electric arrows to knock out the agents and Natasha was shooting at the H.Y.D.R.A. agents legs.
Thor was throwing his hammer at the agents while shouting the battle cry, "For Asgard". Tony was firing repulser blasts but being careful as he aimed so he wouldn't hit the girl. Hulk was, well he was smashing then only one H.Y.D.R.A. agent was left Hulk picked him up and dropped him immediately knocking him out while saying, "Puny agent".
Steve looked at Tony and said, "Can you open that tube?", while examining the panel Tony opened his Iron faceplate, looked at Steve, and said, "Sorry Capsicle I might kill her, Banner would have a better chance of opening it without her dying". Steve nodded and turned to the Hulk, "Hulk were gonna need Banner to help the girl" with a small grunt Hulk shrank until a regular sized Bruce Banner stood before the rest of the Avengers with a smirk Bruce said, "You called".
Tony smiled, "Good to see you Banner I need your help with opening this" while gesturing to the tube with the girl in it. Banner nodded and moved to the panel and after a few minutes of pushing buttons and setting levers with a sudden hiss the tube drained itself and opened up causing the girl to fall forward right onto Thor. The God of thunder gasped, "A little help" then the girl started shrinking to until she looked like a regular girl the only differences was the collar on her neck that read (F/N) (L/N) and the fact she looked like she had malnutrition.
All of the Avengers stared in absolute silence until (F/N) opened her (E/C) eyes and whispered, "Help" and closed her eyes. Immediately Steve tapped his ear piece and said, "Fury we have a injured bystander bring a medical team" then with another glance at the girl added, "We should also detain her for questioning". Fury's reply came quicker than expected, "Why is that Roger's?" Steve had a deadly serious look on his face, "Just trust me we have allot to discuss with her".

(F/N) opened her eyes and looked around the completely grey room the only other person there was a bald man with an eyepatch. Before (F/N) could start the conversation the man interrupted, "I'm Nick Fury the director of S.H.I.E.L.D. who and what are you?". (F/N) blinked a few times surprised at Fury's immediate need to get to the point after swallowing a breath of air, "My name is (F/N) (L/N) I'm a mutant". Fury nodded and looked at (F/N) again and asked,"Do you know what you are though?"
(F/N) nodded and thought back to the D.N.A the bad people had spliced her with she was 50% Siberian tiger, 8.3% alligator, bull shark, black mamba, hawk, wolf, and swan but that was only when she turned into that thing. So she said, "I was just a regular person that was captured by H.Y.D.R.A. they combined several pieces of animal D.N.A to mine but thats only when I want to look like that". "Why? wa the only response from Fury (F/N) shrugged and said, "They just took me one day".
Fury studied (F/N) and after a few minutes of uncomfortable silence Fury continued, "Miss (L/N) you are to dangerous to let go so I leave you with a choice you can either be killed or you can join the Avengers it's up to you". (F/N) took a deep breath and said, "I'll join" Fury nodded once more and said, "Good you start tomorrow" and Fury left the room leaving to (F/N) her thoughts which was far worse than death.
---------------Time Skip------------------------
"So let me know if you feel pain" Bruce said as he pulled softly on (F/N)'s tail after she joined the Avengers Fury took her to Bruce to have a medical examination. (F/N) couldn't believe this gentle man could turn into that angry monster the Hulk, "Let me ask you a question? Do you feel in control when you change into the Chimera" Bruce asked immediately snapping (F/N) out of her thought's she answered him, "I fell like another person that's driven by something and it scares me I feel like I might hurt someone besides myself". Bruce nodded as he was one of the few people that could understand what she were going through, "I feel that way when I turn into the Hu... I mean the Other guy".
Bruce looked down like it was to much for him than he looked up and said, "Any way I'm finished your in perfect health" (F/N) smiled at the man that she had to admit was kinda cute. She got up and started walking forward the elevator but stopped herself she turned around to the doctor and said, "Doctor Banner would you like to talk about it sometime". Bruce looked up at (F/N) and said, "You want to talk with me?" (F/N) nodded with a smile which Bruce quickly returned.
(F/N) continued with Bruce and said, "How about coffee sometimes" Bruce gave (F/N) a big smile and said, "I'd like that". (F/N) smiled and replied, "Great it's a date" Bruce nodded as (F/N) nodded back she turned and head to the elevator she had never been happier.
