Bianca has a father who worries about her, and made her promise to come home if she loses to Elesa, when they are shortly reunited in Nimbasa City. But thanks to Ash, Iris and Cilan, Bianca's dad realized how great traveling is and allows Bianca to stay on her journey to become strong.
One of the gags Bianca performs in the anime is that every time she runs into Ash and his friends, she accidentally knocks Ash into a nearby body of water. There is speculation, though, that Bianca runs into Ash on purpose and knocks him into a body of water to see him with his shirt off.
Emboar is Bianca's primarily used Pokémon. It has many powerful attacks at its disposal including Heat Crash and the powerful Flame Charge which allow it to severely damage its foes. However, despite this, it fell in battle against a wild Minccino and then later fell to Ash's Pikachu in another battle. It later appeared in BW073 in it's final form, when Bianca used it to win against Trip.
When Bianca first saw Minccino, he had stolen the Badge Case that Bianca was delivering to Ash as it was dirty. Minccino is rather eccentric and likes to clean everything. Despite this, it is also a powerful battler and knows the strong moves Hyper Voice & Double Slap, but he can also disable his foes with Tickle and Attract. Bianca managed to capture it by bringing out a dirty Poké Ball. Minccino quickly went to clean the ball but it accidentally activated it and got captured.
Escavalier appeared as a Karrablast that was originally owned by Professor Juniper. Until it was traded to Bianca (in exchange for Bianca's Shelmet), resulting in its evolution into its final form. At first it was very disobedient towards Bianca.
It appeared in BW051. It's known moves are Protect, Acid, and Energy Ball. Bianca traded it to Professor Juniper, in exchange for a Karrablast (which subsequently evolved into a Escavalier). As it was traded for a Karrablast, Shelmet also evolved (into Accelgor).
