Johnson (S.H.I.E.L.D.)

Agent Johnson is a S.H.I.E.L.D. agent meant to help Nick Fury find out what Thaddeus Ross' "Super-Soldier Program" did to Bruce Banner.

Early life
The only known thing of Johnson's past is that she joined S.H.I.E.L.D.

Helping Fury find Bruce Banner
Nick Fury tries to earn Bruce Banner trust, until he eventually tries to test his abilities by making two S.H.I.E.L.D. agents, Johnson and Peterson, appear to be dating and make it appear that Johnson is cheating on Peterson with Bruce, which makes Bruce confused about the situation. The other starts to fight Bruce, but Fury tries to act like he's going to help him, but Peterson punches him in the face.

This turns Bruce into the Hulk and he goes on a rampage. Fury and everyone else in the bar is surprised by his transformation. Fury tries to calm him down, but Hulk yells at him causing nearly all the glass in the room to shatter. Fury doesn't move at all. Hulk then runs out through the wall.
