Claim to Fame

British born, biochemist genius specialising in human and alien life sciences


One of the youngest and brightest members of S.H.I.E.L.D.’s science division, Simmons obtained her first pHD at the age of 16. Simmons is also known as half of the “Fitzsimmons” along with her partner, another of S.H.I.E.L.D’s young, best and brightest Leopold Fitz.


British born Jemma Simmons was an extremely gifted child, obtaining her first pHD at the age of 16 that caught the attention of S.H.I.E.L.D. After being recruited to the Academy of Science and Technology, Simmons studied her second pHD in biochemistry which she completed in 1 year, at the age of 17. To date, this accomplishment makes Simmons one of the two youngest graduates of the academy.

During her time at the Sci-Tech academy, Simmons met and became close friends with another brilliant young scientist, Leopold Fitz. The two became research partners and it was during this time the pair became known as ‘Fitzsimmon’ across many levels of S.H.I.E.L.D.

On from graduating the academy, ‘Fitzsimmon’ was posted to a Sci-Ops facility to conduct research but Jemma wanted more and finally convinced Fitz to accept a field posting.

Character Details

Jemma has a bright and bubbly personality tempered by a calm, accepting, forgiving and merciful nature and a deep abiding love for science.


Image Name Relation Information
medium.jpg Leopold Fitz Joined at the Hip Fitz and Simmons have known each other since SHIELD academy. They are so close, and so often together that they are regularly called by a joint name - Fitzsimmons. She wishes it were Simmonfitz.
May2.jpg Melinda May Boss An extraordinary Agent who is not to be trifled with.
medium.jpg Phil Coulson Boss Much more genial than May, runs the show. Or at least the part of the show that Simmons deals with.
Triplett.jpg Antoine Triplett Field Agent A smart Agent who has been helpful in the lab before. Not afraid of taking blood from May, which is quite a mark in his favor.
Cap-Main.jpg Steve Rogers Hero A sweet man who has attempted to get her to step out of the lab every once in awhile. She's attempting to not use the time to study him like a scientist.
