"He couldn't possibly just be looking to find a sense of belonging among his peers." Jason analyzed, "Judging by his behaviors, his anti-social symptoms are too severe. His mind is probably already a mess. Such a person's emotional reactions are abnormal; there's no need, nor would he seek any sense of belonging. Therefore, it must be for some benefit."
"But what benefit could he gain from the Joker merging with Batman?" Nightwing asked.
"Instead, let's ask what benefit your universe's Batman could gain from this? Why would he be looking for this particular Batman?" Jason said.
The Robins from the Prime Universe were silent, pondering, but they clearly couldn't see the purpose behind their universe's Batman doing such a thing either. At that moment, Jason said in frustration, "I mean, ask him. As long as you know the purpose of your universe's Batman, wouldn't you know King Robin's too?"
"Ask???" Red Hood showed a great degree of puzzlement and shock; to him, this seemed hardly an option.
The Robins from the Prime Universe looked at each other, and then Barbara said, "This mysterious fog seems to have disrupted the signals. When on earth can we get out?"
Upon hearing there was no signal, the Robins from the Prime Universe breathed a sigh of relief, as it seemed they had been preparing for a free-for-all to decide who would ask Batman the question.
"Come on, it's not like there will never be a signal again," Tim's comment let the dangling hearts of the Robins from the Prime Universe fall completely dead, and then Jason added fuel to the fire, "I really don't know why you're so afraid of him — it's not like he's going to eat you, and besides, you're going to ask about something serious, not chit-chat."
"Chit-chat isn't an option in Batman's list of dialogue topics," Red Robin said subconsciously. But then he thought for a moment and added, "However, he has been a bit more approachable lately, even talking to me about Holmes, which is so strange."
"That could also be part of his plan," Red Hood was still reluctant to admit.
The filtration system stopped working, and it seemed like the fog had cleared. Barbara operated the computer, and after the screen, which had been showing static, flickered a few times, the camera feed finally came through.
"The fog is gone — oh no, good heavens, where have all the Batmans gone? How could they disappear?"
"How could you expect a bunch of Batmans to stay put during something like this?" Dick said with some regret, "Had I known, I would have told you earlier. We thought the Guest in the Fog wouldn't come to such a remote universe."
"Let's head out first." Barbara was the first to push her wheelchair and head out.
After returning to the living room, they found that the furnishings hadn't changed. Alfred came out of another door from the Batcave, and Jason yelled out just as Alfred walked in.
Seeing the Robins emerge, Alfred said, "Glad we're all okay, but just before I went in, I saw the thick fog engulf our group of guests."
"It shouldn't be a big deal, so far there haven't been any reports of the mysterious fog harming anyone. Most just wander aimlessly in the fog, get disoriented and panicked after being transported, or get so scared by those dreadful eyes that they go see a psychologist."
"Once the fog lifts, the signals will come back, and then it's just a matter of phoning them," said Jason, who was not really nervous. But then, suddenly, a scream came from behind; Barbara looked at her tablet and exclaimed, "Oh my gosh, someone has fainted at the door, we need to get there fast."
Red Hood and Red Robin, who were at the front, rushed out immediately and found a postman collapsed at the entrance with his deliveries scattered all around.
"This seems to be Mr. Handel," Red Robin recalled, "Remember the time he delivered our mail? It turns out he's a postman in this universe too."
"Quick, bring him inside." The two of them clumsily carried Mr. Handel, the postman, back into the living room, where Barbara had already discovered from the surveillance cameras that there were quite a few people collapsed on the nearby streets, all of them ordinary folks.
"Good heavens, didn't you say this kind of fog wouldn't harm people?" Barbara said. "They've all fainted."
The two universes' Red Robins performed a basic medical check on Mr. Handel, then said, "He did indeed faint, but he just fainted, without any injury. It appears he's been hit by some kind of neurotoxin."
As soon as the word neurotoxin was mentioned, all the Robins from the Arkham Knight Universe took a deep breath and roared out a name, "Spider-Man!!!"
"Aren't you afraid those bunch of Robins will come at you?" Poison Ivy asked while driving, recalling, "That Spider-Man kid seemed to have a pretty hard time being chased last time. They even had a big fight."
"Then he will continue to be chased miserably, and they will keep fighting," Shiller replied calmly.
Poison Ivy didn't quite get his meaning but Shiller didn't elaborate, simply gazing quietly out the window.
Meanwhile, in the great hall of Battleworld, a Spider-Man was walking when he saw a sign appear at the end of a corridor, reading "Spider-Man Not Allowed" with a prohibition symbol over an icon of a pair of spider eyes.
This Spider-Man scratched his head and stealthily crept along the wall towards the corridor that bore the sign. Peeking around the corner, he saw it was just an ordinary corridor with nothing particular, but there appeared to be another sign at the end of it.
```
So he sneaked over again and saw another sign painted with an arrow, saying "Spider-Man No Entry."
Spider-Man glanced down the corridor but still found nothing, yet there was another sign at the stairway.
Spider-Man approached it and read "Severe Warning, Spider-Man Absolutely Forbidden from Entry," this time the warning sign was in a bright red.
Spider-Man placed his hands on his hips and cocked his head, squinting the spider eyes on his mask, then strode up the stairs.
After ascending a floor, Spider-Man indeed saw a sign at the entrance of a room stating "FBI Warning, All Spider-Men Strictly Prohibited from Entry."
Spider-Man huffed, yet carefully approached the door, first listening for any noise inside, then quietly turned the doorknob, pushing the door open slightly, and finally tiptoed through the gap.
But the room was empty, with only a lone button sitting on the floor.
Spider-Man walked over and picked up the button, feeling it looked familiar, as if it resembled a part dismantled from a transport hall's portal.
However, the thought quickly passed. After all, who would dismantle a transporting device for no reason, and even if they did, why place it in this room and put up a sign forbidding Spider-Man from entering?
Spider-Man carefully surveyed the surroundings and listened to his Spider-sense, which gave no alarm, he then went ahead and picked up the button.
It was a red, round button, often seen in various cartoons, the kind that would produce a mushroom cloud in the distance when pressed, with a no Spider-Man symbol still painted squarely in the center.
"Heh, child's play," Spider-Man couldn't help but mock, "Do they really think I'll press it just because they drew this? Not a chance."
Just as he was about to put the button down and walk away, it was as if he remembered something, He took out his phone, turned around, held the button beside his face, and prepared to snap a selfie to post on a forum.
After taking a good picture, Spider-Man checked it and noticed it actually turned out quite well—quirky and comical—sure to get a lot of likes, so he began typing up a tweet.
"Encountered another weird thing today, someone left a button like this in the room, what do you all think it means?"
Soon after the tweet went out, his phone started chiming incessantly, but upon opening the notification system, he found the increasing red dots were not likes but comments.
"Behind you," "What's that light behind you?" "Is this some kind of strange performance art?" "Be careful! Behind you"...
What's behind me? Spider-Man glanced at the photo again and noticed a small light spot behind him, assuming it was just some dirt on the lens during the photo taking, he reached out to wipe it but then realized he couldn't quite see the phone screen clearly because a bright light was shining behind him.
Spidey-Sense alerted him at that moment, and a huge force of suction came from behind Spider-Man.
Whoosh!
After the portal closed, there was a click, and only the phone fell to the ground, the comments and messages still multiplying, all the information scrolling across the screen warned him to be careful of what's behind.
With a thud, Spider-Man crashed onto the ground, clutching his waist and letting out a pained yell. He staggered to his feet and rubbed his almost-split-in-half behind.
Looking at the immense strange city, Spider-Man was a bit dazed. He blinked at the towering skyscrapers, the streets filled with neon lights, the overcast sky, and the variety of flying vehicles, and suddenly recalled a sensational masterpiece he had read on the forums—"Gotham Travel Notes."
Although the city looked somewhat different from the description in the travel notes, Spider-Man recognized the name Wayne on the tallest building against the skyline.
Spider-Man was ecstatic. He had always been a devoted fan of the two Spider-Men who wrote "Gotham Travel Notes" and "Gotham Postscript." However, being a new Little Spider from an obscure cosmos, with neither particular combat power nor special settings, Nick would never approve of him going to the remote and dangerous Gotham.
But now, he finally could...
"Spider-Man!!!!!"
A roar came from above Spider-Man's head, and as he looked up, he saw a small ship slowly revealing itself, followed by a group of bread-headed people jumping out.
"Spider-Man, why are you doing this again? Are you a superhero or a terrorist? You almost destroyed Gotham! Twice... Three times!!!!"
