Bianca only recently started traveling as her father just wouldn't allow her to start a journey when she wanted to. She is fully motivated for battling and getting gym badges but considers herself quite lazy when it comes to cleaning chores. She is also very eccentric and clumsy. Her purse contains many items that she carries around with her but the inside of it is quite dusty. When she originally met Iris and Cilan, she told them she had two badges at that time.
While on route to Shippo City, Ash Ketchum and friends bumped into Bianca. She had been looking for Ash Ketchum to deliver a badge case to him from Professor Juniper. Before she could deliver it to him a Chillarmy took the badge case because it was dirty. She instantly fell in love with the Chillarmy and decided she wanted to get it. She attempted to capture it by setting traps but it wasn't until she took out the monster ball to catch it that Chillarmy noticed was dirty and ended up capturing itself.
Bianca is also a main character in the 5th generation games Black and White. Players encounter and battle her throughout the game.
Link Trade Machine and Tag Battle Against Ash and Cilan
Professor Juniper brought her link trade device to investigate the influence the Electric Stones have on evolutions. She setup the device at her base camp outside the caves. She agreed to trade her Karrablast for Bianca's Shelmet using the machine after they figured out what was causing the electric abnormality that was affecting the machine.
After the battle, Professor Juniper checked both Bianca's Escavalier and her Accelgor's data to notice that their power has increased by a whole lot. She also noted that they fought really well even though their opponent Cilan was Gym Leader.
Isshu League Tournament
Bianca managed to get the 8 necessary badges in order to participate in the Isshu League. In the preliminary round of the Isshu League, Bianca's Emboar was matched up against Mikael's Watchog and easily defeated it. As a result Mikael was eliminated from the competition and Bianca advanced to the first main round of the Isshu League Higaki Tournament.
