Tiffany Michaels was born in San Francisco, California roughly twelve years before the Chrell Invasion. When the Invasion happened, she was was forced to flee her home and was taken in by S.H.I.E.L.D. From a young age, she has been a fighter and soldier, and that's her outlook on life, that life is nothing but one battle after the next. Her entire family was killed during the Chrell Invasion and she turned towards Dominic Smith as a surrogate father. When the Invasion was over, she expressed an interest in joining S.H.I.E.L.D. as an operative. Nick Fury was against this, as she was still too young to be doing anything in S.H.I.E.L.D. When she turned eighteen though, he didn't have much of an argument anymore, and she was accepted into the ranks of S.H.I.E.L.D.
