"Ra's Al Ghul
Name: Ra's Al Ghul
First appearance: Batman #232 (June 1971)
Ra's Al Ghul ("demon's head" in Arabic) is a centuries-old eco-terrorist. He knows Batman's secret identity. He utilizes special pits known as Lazarus Pits which enable him to evade death, and live for centuries. He is the founder of the worldwide League of Assassins, though exactly when this occurred is unknown."
"Batman gets involved with the conflicts in his new "family" i.e. Ras Al Ghul, Talia and Damian. This is the weakest of the four books in the Batman:RIP storyline. It covers ground between the three that is already very well covered. Still, the writing is good and this book is book-ended by some great stories."
