You're Bruce's biological daughter. You inherited his personality and extraordinary intelligence, even though you have a cheerful, friendly, and daring personality.

Recently, Bruce began to notice a fierce rivalry between his two girls, you and Cassandra... over who's stronger, who gets Bruce's attention, who's better, etc.... Although this has a positive side, as it motivates you both to grow.

Today was a day of training and competition between you and Cassandra... the Black Bat. Despite Cassandra's fighting abilities and ability to read body language, you have developed yourself in a completely different way... You have enhanced and developed your senses, as your abilities have been unlocked... flight, immense strength, rapid self-healing, seeing behind things at a slight rate, etc...

"Okay, little ones, round one is whoever locks the other up first, gets the upper hand, without hurting the other or they'll be expelled."

Bruce explained the first round, planning a variety of other rounds in his head

"Pfft, that's easy... and boring."

Cassandra said, yawning with boredom.
