Katee Sackhoff’s tattoos range from a large winged design on her upper arm to a small E=mc2 formula and a yearly series she and her husband, Robin Gadsby, make for their daughter. In October 2026, she posted the fifth family design: Wonder Woman.

The Winged Upper-Arm Tattoo

A Starbuck-era still shows the winged tattoo running down Sackhoff’s upper arm. A broad circle anchors the lower part; above it, an angular center opens into feather-like points toward the shoulder. The black lines form a tall, graphic shape across much of the arm.

Below the circle, a narrow line ends in a small loop, with a compact geometric mark beside it. Sackhoff’s sleeveless costume leaves the tattoo in clear view, though the cited coverage does not explain its personal meaning.

The Winged Design in the Starbuck Portrait

A closer Starbuck portrait makes the upper strokes easier to see: tapered black wedges separated by slim spaces of skin. The wider ring below them breaks up the dense feathering and gives the design a more open shape.

Another View of the Winged Upper-Arm Mark

An E! Online still shows the same piece from farther away. The ring sits near the elbow, while the feather-like forms narrow as they rise toward the shoulder. The broader view shows how much of the arm the tattoo covers.

The E=mc2 Inner-Arm Mark

A Tuko photograph shows E=mc2 on Sackhoff’s inner arm, a short line of characters beside the much larger winged piece. Tuko also lists a Chinese inscription it translates as “choice,” a Latin phrase and a black cross; those descriptions come from that profile.

The Wonder Woman Symbol in the Family Series

Sackhoff’s October 2026 Instagram post shows a small Wonder Woman emblem and identifies it as the fifth tattoo in the series. The compact outline is easy to distinguish from the broad black design on her upper arm.

CinemaBlend reports that Sackhoff and Gadsby add one tattoo each year for their daughter, following her childhood cancer treatment. The family ritual is the context Sackhoff gives for this series.

A Timeline in Five Small Marks

The five designs, in order, are a plane, a book, Sackhoff’s monkey, the heart of Te Fiti and Wonder Woman. Her caption names them but does not give a separate personal meaning for each one.

How the Collection Develops Through Time

That sequence is the only timeline the cited sources establish. They do not date the winged tattoo or E=mc2, so neither can be placed among the five yearly additions.

The photos show the winged design’s shape and placement, while Tuko describes several other marks. The available sources leave the personal meaning of the winged tattoo unstated; there is no basis here to assign it a story.
