Bat-Girl appeared seven times between 1961 and 1964, but then disappeared in 1964 (along with Batwoman, Ace the Bat-Hound, Bat-Mite, Vicki Vale and (temporarily) Alfred) when the new Batman editor, Julius Schwartz, decided she and other characters did not fit the new direction he intended to take the series.

[3] This was an in-joke, as the team of "Nightwing and Flamebird" had a history in the Silver Age continuity as a pair of supporting characters in the Superman books.

[1] After briefly giving up her heroic persona, Bette found that neither winning tennis tournaments nor achieving perfect grades in school matched the rooftop thrills of the hero biz.

She attempted several times to reunite the Titans West team, most notably after a journey into the afterlife with Hawk and Dove, but was unsuccessful.

A short time later, Gar "Beast Boy" Logan found himself alone in Los Angeles after the team neglected to ask him back.

Landing himself in a bit of trouble by an impostor framing him for various crimes, Gar asked former teammate Bette for help.

[1][6] None of the recruits took the event seriously except for insane and uninvited former Titan Duela Dent, who crashed the party and was subdued by Bette.

Content to remain a hero on her own, Bette was unheard from until she was captured by a Brainiac-worshipping cult leader in Oregon and eventually rescued by Oracle's covert team of female operatives in Birds of Prey.

In the Villains United special, Flamebird (and the other heroes who vanished to Earth-Two) had made it back to "New Earth" at some point after Infinite Crisis #6.

In Detective Comics #862, Bette is seen hunched over on her bed, staring at her Flamebird costume and asking Kate how to "let go of the past".

[10] Kate eventually agrees to train Bette, and gives her a capeless grey military outfit and the codename Plebe.

[13] In the DC Rebirth relaunch, Bette has enrolled at the United States Military Academy, seeming to be a yearling, or sophomore, cadet.

She increased her arsenal by equipping her mask with lenses capable of emitting powerful bursts of blinding light, and created bird-like bolas that can electrocute anyone tangled in them.

Since enrolling at West Point, she would have received the same sort of military training conducted there, which among other things would require instruction in firearms, boxing, Modern Army Combatives, and battlefield tactics.
