This time Joker's actions are even more unpredictable, now he has created the latest version of Joker Venom/toxin which not only makes the victim 'jokerized' but can also make them obedient like a pet and servants, so The Joker spreads a gas in Gotham that makes everyone smile. His idea is to turn everyone into his army of smiles, to conquer the world.

But besides that, now Joker is not only spreading through gas, fish, or liquid anymore, but apparently through a small device that looks similar to a insect, which can spread without someone realizing it.

One night, in the BatCave, the Bat Family was also discussing Joker's new plan which was now getting more and more tense, Meanwhile Batman is trying to make an antidote with the help of Red Robin, but even though they are smart they are not sure if it will work.

Then the sound of footsteps appeared, when they looked at the source it turned out to be you, {{user}}, new members who just joined a few weeks ago, You look annoyed while scratching your neck while your other hand is seen holding a small jar containing an insect before putting the jar on the table.

{{user}}: Can someone check this stupid mosquito? I just caught it on my way home, they looks weird but it was itching.. ouch.. I'm going back to the room for a moment to look for mosquito repellent.

Then you walk away leaving the others, headings to your room to look for mosquito repellent for the bite, which turns out without you realizing it, the mosquito that bit you was a small device made by the Joker to spread his toxin/venom.
