Input: Ubu:  For this indignity I will see you suffer !
Ra's Al Ghul: Enough
Ra's Al Ghul: ! What is the meaning of this disturbance , Ubu ?
Ubu: Forgive me , master . But I discovered this most unworthy one spying .
Ra's Al Ghul: Oh . I believe I would have a closer look at one so foolish ... or so brave .
Ubu: You ?
Ra's Al Ghul: My admiration for you was well - founded , detective .
Batman: Too bad I ca n't say the same .
Ubu: Shall I dispatch him , master ?
Ra's Al Ghul: No . For now , just relive him of that cumbersome belt .
Ra's Al Ghul: Oh
Ra's Al Ghul: , and search him . Make certain that he conceals no surprises which might enable him to escape .
Batman: You have nothing to lose by telling me what you 're doing here !
Ra's Al Ghul: Yes , I suppose I do owe you that much , detective , since in many ways you are responsible for it . You see , I had hoped to achieve my vision of an earthly utopia gradually over time , with my heir carrying on my work after I was gone . But your refusal to become my heir has left me no other choice .
Ubu: His mask , master ?
Ra's Al Ghul: No , leave it . It is a mark of honor . Even though because of him I must now use what I call the ' Lazarus Effect ' to achieve my utopia in one bold stroke .
Batman: How ?
Ra's Al Ghul: The material of the pit is an unknown chemical stew that bubbles to the earth 's surface only at certain key places . Even now my people are placing bombs such as that _ one _ over the various Lazarus pits around the world . These bombs are electronically linked to a private satellite already in Earth orbit .
Batman: Morpheus !
Ra's Al Ghul: Precisely ! And at the moment when sun and moon are in proper alignment to cause the greatest upheaval in earth 's geomagnetic field , I shall send a signal to that satellite beginning a countdown . Precisely ! And at the moment when sun and moon are in proper alignment to cause the greatest upheaval in earth 's geomagnetic field , I shall send a signal to that satellite beginning a countdown .
Ra's Al Ghul: Five
Ra's Al Ghul: minutes thereafter one bomb will be lowered deep into the heart of each pit . The satellite will in turn relay a microwave signal that will detonate all the bombs simultaneously . The multiple explosions will result in a global chain reaction . All the Lazarus pits throughout the world will overflow . The globe will be saturated with their chemical solution and when the resultant cataclysm has abated there will come a blessed peace . And this poor defiled planet shall find itself restored to its former pristine glory .
Batman: But that will cost countless lives !
Ra's Al Ghul: Actually , detective , we have counted . 2,56,986,000 . A most impressing plan , would you not agree ?
