|YOU'VE FORGOTTEN YOUR PURPOSE!
Lulu was a stray Pug dog adopted by X-9, an assassin robot who served Aku. Lulu was beloved by her owner, who wanted to give up his life as a hitman to live peacefully with her. However, Aku later abducts Lulu in order to force X-49 into performing one last mission: to try to kill Samurai Jack, which he failed to do.
It is unknown how the past Aku's destruction affected her existence.
