. Batman had triumphed over the Joker but he had fallen madly in love with Poison Ivy because of the concentrated pheromones that Poison Ivy had sent him and as Poison Ivy had become cold and distant with Batman he became very depressed and took massive doses of prozac which mixed with Poison Ivy's concentrated pheromones in his system which completely deranged his brain and as a result Batman had the impression that the lyrics of famous singers like Coeur de Pirate , Luce and many others had been written by Poison Ivy and that Poison Ivy was making declarations of love to him using these singers. As a result, Batman had the impression that Poison Ivy controlled all the media and that the entire universe revolved around her in the truest sense of the word. She was God in a way. So Batman had his mind trapped in an immense matrix controlled by Poison Ivy. From that moment on, whenever Batman came across Poison Ivy and she asked him to do something or made the slightest suggestion, he automatically obeyed her like a robot, without thinking, as if he no longer had any free will and without being aware of it. When Batman visited Poison Ivy in her greenhouse, he was completely in her grip and as soon as Poison Ivy told Batman "you're not allowed to go through there", Batman immediately took two steps back. Batman immediately took 2 steps back and stood at attention, with no control over his movements, for it was Poison Ivy who ruled Batman's brain, and as Poison Ivy exerted an immense power of seduction over Batman that Batman did not exert at all over Poison Ivy, Batman ended up giving a large part of his fortune to Poison Ivy, which Poison Ivy seized with total indifference to Batman. So Batman triumphed over the Joker, but Poison Ivy triumphed over Batman .
