Hey everyone! This is my first Marvel based fanfiction, but I've loved all things superhero for years and years. I'm excited to finally try and put a story together! I hope you all like it! And please comment/ review. The more I get the more I want to continue (especially if people enjoy it). I might change the rating as chapters progress so just an fyi. This story was based off a comic I started last year and I might try and finish it and post pics. on my Deviantart. So enough of this, here it is!

All characters belong to Marvel/their respective owners. I did create the plot though.

"Tony? Tony can you hear me?"

Static

"Tony? Maria he's not answering."

"Stark I need immediate confirmation on your location…Stark? Dammit Stark if this is one of your tricks…"

"We've lost his bio-signature."

"…"

"Maria?"

"I'll contact Director Fury. Pepper, try to locate the rest of the Avengers."

"Tony please…Please be ok."

"Felicia Hardy, known by her alias as Black Cat." Maria Hill slowly circled around the autopsy table motioning towards the cause of the victim's death. "One bullet in the chest. Clean. Precise. Definitely an expert kill."

"Well how many experts do we know that could have done this?" Steve Rogers said, solemnly gazing into Hardy's glazed eyes. "What monster could have targeted her?"

"Well see that's the problem," Hill sighed and pulled papers out of a file from under her arm. She laid them over the table for everyone to see. "We know too many expert assassins. Narrowing them down with motives is where things get fun." Knowing her last comment was directed towards them, both Tony and Hank crossed their arms in frustration. By "narrowing them down," Hill meant Hank and Tony would spend hours of researching in the lab to solve the case.

"Yeah fun." Tony's voice was thick with sarcasm. "I hope you have more for us to work with than this?"

"Did you find a bullet?" Hank asked.

"As a matter of fact," She lifted a small case from a nearby desk, "we did." She handed it over to Tony. "Happy Birthday."

"Just what I wanted." Tony replied with a forced smile.

"How can I assist Maria?" Steve asked, walking up next to Hank.

"I need you and Natasha to help me with the media. We do not want the world to know that one of our own has been murdered. Probably wouldn't make for a good evening news story."

"Of course ma'am. " Steve nodded in acknowledgement and dismissed himself from the room.

"See Stark when will you be more like him?" Maria teased. "You know follow my orders without witty back talk?"

"The day I decide to wear a star spangled flag for a costume." He retorted, examining the bullet closer. "And you really think I'm witty?"

"Contact Thor," She changed the subject, "I want him on standby until we know what's going on." She re-covered the corpse with a sheet and turned to leave. "But seeing as our killer has every intention of raising hell, we'll probably need all the help we can get."

Please review! Next ch. coming soon!
