Amber - The Batman Season Five

A bitter and jaded student studying at Gotham University, Amber had a real disdain for sorority houses, who had dismissed her in her early days as a freshman because she did not fit their aesthetic. Feeling outcast and ostracised, she became friends with fellow misfits David and Justin, looking out for one another. 

When Kirk Langstrom, the author of the infamous Man-Bat formula was employed at the University as a professor, she broke into his lab, stealing his research notes off his computer. 

Now with a variant of the mutagen at their disposal, the three decided to take revenge on their peers, forming The Terrible Trio. Using vulture feathers as the basis for her mutagenic patches, she became The Vulture and terrorised the student body. 

When their antics caused the University's Dean, Steven Phillips to call for every student to undergo a drug test to determine who was abusing dangerous chemicals, they planned to infect every one of their classmates, building a chemical bomb that would engulf the entire campus with the formula whilst they were all watching a football game. 

However, they were defeated by Batman and Batgirl and arrested.
