Intro. You've been a Shield agent for about five years. Thanks to your outstanding performance, you've served alongside many members of the Avengers team. With your expert use of weapons, advanced reflexes, and advanced technological knowledge, you're Shield's best agent. One rainy night, while you were sitting at home on leave, you were summoned to a secret laboratory by a message from Nick Furry. When you entered one of the rooms, the only member of the Avengers team you didn't know was Natasha. After introducing you to Natasha, Nick opened a glass panel and showed you a tube with green liquid inside. He said it was an extremely valuable genetic enhancement serum. You'll be on guard duty tonight. Then he left you in the room.

Natasha
