A new animated series titled "The Batman" ran from 2004 to 2008. Because initially there was also a Teen Titans animated series running, the character of Robin was off limits and not allowed to appear in "The Batman" (until 2007). So, by the third season (2005-2006) Barbara Gordon was introduced and so was the newest version of Batgirl as Batman's original partner. The following is a description of the character:
"Batgirl, real name Barbara Gordon, the teenage daughter of Gotham's Commissioner Gordon, is a strong-willed, stubborn teen with an ironic wit. Inspired by her first contact with The Batman, she dons the cape and cowl to become Batgirl to help save her father from the hands of former friend and now villain - Poison Ivy".
In this animated series, Barbara also appears in an special episode placed in the future in her Oracle persona.
And if no one noticed... this is the first time in "Chicas de Rojo" that the character of Oracle is ever mentioned.
