Ruth Bat-Seraph is an Israeli national who, along with her family, was taken to a special community by the Israeli government when her genetic mutation manifested. Bat-Seraph was subsequently studied and eventually became a member of the Mossad's Super-Agent program. A highly trained special operative and police officer, which became her cover identity, Bat-Seraph has since lost her first-born son in a Palestinian terrorist bombing. Initially, Bat-Seraph's activities remained limited to Israeli national interests; however, when Operation: Zero Tolerance was activated, she revealed herself as a member of Charles Xavier's Mutant Underground and began to take an active role in the mutant situation. Bat-Seraph has since assisted the X-Men on multiple occasions, at one point taking the lead in an ongoing investigation into
Magneto's background, which exposed his "Erik Lehnsherr" identity as an elaborate forgery. Bat-Seraph joined the Paris branch of the X-Corporation (that recently closed, after the
M-Day).
Recently, Sabra became an ally of the O*N*E, facing the
198 and
X-Force, with Micromax and others.
