Manhunter is a fictional character, a superheroine in publications from DC Comics. Kate Spencer is the eighth DC Comics character depicted using the name Manhunter, and the first female to do so. The character first appears in Manhunter (vol. 3) #1 (October 2004) and was promoted by DC Comics as relevant to the popular Identity Crisis limited series.

Despite critical success, the first series has repeatedly had trouble gaining larger readership. DC Comics announced in May 2006 that the series would be canceled and that issue #25 would be the last. Dan DiDio, DC's executive editor, soon followed with another announcement, that fan outcry convinced him to extend the series for five additional issues in order to improve sales. The new five-issue story arc dealt with a ramification of the Infinite Crisis, again tying the series into a popular event. Didio also said that the storyline leads into another big event in the DC Universe. The series came back with issue #31 in 2007, but was cancelled with issue #38 in 2008.

She will have a 10 page co-feature in Batman:Streets of Gotham beginning in June.

Kate Spencer is a federal prosecutor who grows increasingly tired of seeing guilty criminals evade punishment. Copperhead, a criminal on trial for multiple murders and cannibalism, avoids a death sentence and escapes from custody after killing two guards. Angry, Kate steals equipment from an evidence room and kills Copperhead. Calling herself Manhunter, Kate blackmails a former weapons manufacturer for numerous villains named Dylan Battles — who is in the Witness Protection Program — into building, maintaining, and upgrading her armor, weapons, and gadgets.

Manhunter (Kate Spencer) has not been a contender in any CBUB matches.
