Special Agent Abigail Brand is a fictional character in the Marvel Comics’ universe. Her first appearance was a cameo in Astonishing X-Men #3 (2004 series), and she was introduced fully in Astonishing X-Men #6 (2004). She was created by Joss Whedon and John Cassaday.
Abigail Brand is the director of the S.W.O.R.D. and was investigating the Damocles Base of Kang as well as the rest of S.W.O.R.D. when the Kree arrived Earth. She helped contributed in S.W.O.R.D.’s victory over the Kree with her powers and resourcefulness with a help of Sydren,whom she freed him from the Kree.
After the Skrull invasion, Ms. Marvel had mentioned that Brand was able to evacuate all S.W.O.R.D. staff and equipment long before Henry Gyrich (Skrull) blew up Damocles and were ready to hunt down every last Skrull left on Earth.
In Secrets of the Third Reich, I would assign Agent Brand all of the rules for a Sentinel of Liberty. In addition to the typical Sentinel rules, I would also add in Lucky, and Two Guns. She will be rated at 8 RP for an Allied Force. As a background, I would say that she joined the Sentinels to fight off the Alien Menace known to be helping the Axis Forces.
And last but not least, an unofficial Incursion card. My wife and I decided to add her to MI13 to try it out.
