## Personality

Tatsu is a competent, intelligent individual who is focused on her goal. She is also a great detective able to find Bruce's secret bookcase. At times, though, Tatsu can be brash, impulsive, impatient, and disobedient. Early on, she considered Batman to be a "nut", and has been shown to have opinions differing from Batman's on the necessity of killing in certain situations. Batman has stated that Tatsu can have an ego, which she argued was simply pride in her work. Like Batman she can be cold and distant but can also have a sense of humor as shown with her interaction with her godfather, Arthur and originally had with Jason Burr. She also shows a softer more compassionate side, shown towards Jason and also shows a seemingly mentor and student or brother and sister like bond with Bruce as shown when they are in the field.

## History

### Past

In the past, Tatsu Yamashiro was a covert CIA operative tasked with tracking down Ra's al Ghul and she joined the League of Assassins and there was known as "Katana".

After completing his training Ra's al Ghul, the League of Assassins was sent on a mission to the south eastern part of Aisa where Tatsu accidentally injures a young girl, who is executed by Scarface. Sometime during the same mission, she later faked her death in a fire and disappeared with the Soultaker Sword, believing it to be too dangerous for either the League or the CIA to possess, in which unknowing to her, Jason Burr (the man she loved), Bethanie Ravencroft (a friend of hers), and Robert Brickson (Slade's big brother) were killed.
