Joker's Infection
Description: Joker uses Titan in Arkham Asylum and he is able to withstand it for a little bit, but we learn that Joker was poisoned by the Titan. He then poisons Batman and all the other residents in Gotham with the blood raising the stakes. Once Batman retrieved the cure from Talia, and then Clayface he was able to stabilize himself. However once Joker stabbed Batman he dropped the test tube spilling the entire cure on the floor. This eventually led to Joker’s death.
Question: What if Joker did retrieve the cure, what would happen?
Answer: He would gain his sanity back and live
How: The cure inserts the blood of Ra’s al Ghul who almost every day inserts the Lazarus Pit. The Lazarus Pit is a pool of chemicals that has been said to cure anybody and extend their life. However if you are healthy and you enter the pit most likely you will die. Only once Joker has taken a trip into the pit and when he got out he had his sanity back but that was for a brief moment. But imagine if he had to be cured, and he took the blood of Ra’s along with the other chemicals. He could gain back his sanity and be cured.
Final Statement: If Joker took the cure the clown prince of crime would be no more and Gotham could’ve been safe.
