Tatsu Yamashiro (山城 達 Yamashiro Tatsu), née Tatsu Hikari (ひかり 達 Hikari Tatsu) [2], is a Japanese samurai assassin code-named Katana (after her weapon of choice) and an infamous master of swordplay and martial arts who trained to the highest level in the ancient art form.
She is a proxy member of the Suicide Squad, and, of note, the only voluntary member who served as the personal bodyguard of Rick Flag.
Early life Tatsu Hikari was born on March 16, 1986, in Tokyo, Japan. She was the only child and supposedly developed deep-seated issues with her father. She trained in various martial arts at a young age, a trait encouraged by her parents. When she reached adulthood, two brothers began to compete for her heart: Maseo and Takeo Yamashiro, yet her decision to marry the former drove the latter into joining the Yakuza and be disowned by his family.
