Amelia Ann McFly

Red Haired Amelia Ann McFly is a female bounty hunter that appears in the 2010 movie, Trigun: Badlands Rumble.

Background
Amelia Ann McFly was born one year after a bank heist by her father, a notorius thief named Gasback. Amelia's mother would not travel with Gasback due to his criminality, so she remained in their hometown and Gasback left her with money on which to live and a metal box containing what Amelia's mother describes to her daughter as "a precious secret".

Despite being left well-provisioned by Gasback, her mothers house was looted by rival thiefs, and neighbours refused to help defend the family of a notorius ciminal. Even doctors would not help her mother when she lay dying, and Amelia holds Gasback responsible for her mothers death.

Aged 19, she travels to Macca City with the intention of finding and killing Gaspack in revenge for the death of her mother.

Along her way to Macca City unknowingly runs into Vash and Vash of course immidiately flirts with her all the way to the city and also during their stay in the city.

She later spends time with Vash and friends at a local tavern and drunkingly causes a bar brawl that eventually esculates to attempted gun fire that failed due to Vash stealing everyones ammo during the brawl.

She later runs into Gasback only to lose him due to Vash's sudden intervention which allows gasback to steal a bulb from the local plant.

She immediately gives chase along with a large number of other bounty hunters but is the only one who successfully caught up to gasback along with Vash and Wolfwood.

She ignores Vash's attempts to make her stop shooting the bulb while aiming for gasback and is immediately shocked when Vash is hit and falls off the vehicle and lands in quick sand where even due to Wolfwood's brave attempt the only thing recovered is Vash's glasses.

Vash appearent death greatly affects Amelia and while wondering through Macca city realizes how badly the town needs the bulb and why Vash risked so much to protect it.

After enlisting Wolfwood in her raid on Gasbacks hideout she attempts to bring the bulb back to the city but fails due to the vehicle being chained down.

She is saved by Vash's spectacular reappearance after he saves her from an enraged gasback and is then a spectator to the duel between Gasback and Vash.

Later after returning the bulb to the city, informs Vash of her strong intent to follow his lifestyle and bids farewell to Vash and Co.
