Several years ago a new (and surprising) character was introduced to the DC
Comics Universe. His name was Damian
and he was (and is) the son of Batman given birth by Talia (the daughter of the
arch nemesis of Batman: Ra's Al Ghul. This
all happened before DC revamped its universe and re-titled it The New 52.
Damian was a trained assassin and when Batman agreed to raise him he tried (and sometimes failed) to curb Damian's killer instincts. Eventually Damian came around. Unfortunately he was killed-but there are hints he will be back.
Warner Bros. Animation has just released a new Blu-ray/DVD/Digital HD Ultraviolet Combo that examines the genesis of Batman's sire and how he came about being with his father.
Ra's Al Ghul is a notorious villain in command of the League of Shadows. He, and his daughter Talia, are training an army of assassins to literally take over the world.
When an unexpected attack occurs on the compound by Deathstroke, who wants to lead the League of Shadows, Talia is forced to flee, taking Damien with her.
She winds up in Gotham City and seeks the help of Batman who soon discovers who Damian is-his son!
Together Batman and Damian face off against the League and Deathstroke and through a series of moves and counter movies discover that the only people they can trust is each other.
The Son of Batman Combo includes not only the movie but several special features including the story of Damian Wayne, how the characters were designed, a special League of Assassins featurette, a sneak peek at the next DC animated movie and four bonus cartoons.
