Bonus Scene: One day, the dark and brooding guy looked at Doraemon and asked in a low voice, "So you're saying the Joker somehow fell into the water, then a goddess appeared from the water and asked whether the clown you'd dropped was this golden clown, this silver clown, or this wicked, hateful clown?" Doraemon nodded like a pecking chick. "Then I said I'd dropped the wicked, hateful clown." "And then the goddess praised you for being an honest child, and gave you both the gold and silver clowns?" Red Hood asked. Doraemon nodded again. The three of them stood facing each other outside Arkham, with the Joker in the background, being dragged into the water by the goddess in the Woodcutter's Spring while struggling the whole time. "Ha ha ha... glug glug... ha ha ha, Batman... glug glug...!!!" The goddess in the water tried to pull the Joker under, but he kept struggling and climbing back up, creating the sound of someone drowning. Red Hood picked up the hammer lying on the ground, stepped on the Joker's hand as he clung to the edge of the water, and knocked him under with one blow. After all that, he rolled up the Woodcutter's Spring spread across the ground, tucked it under his arm, and turned to Doraemon and the dark and brooding guy. "How about this? You two pretend you didn't see me today?" Completed: [Western Crossover] What's It Like to Take Online Classes in Gotham? Next: [Western Crossover] As a Wicked Female Lead, I Don't Fit in Gotham I wrote the beginning of this one a while ago, but stopped updating because I got stuck. I'll revise it and start updating after I finish this story. Feel free to check it out if you're interested. Reading Guide: 1. Doraemon is a lighthearted, silly children's manga, and this story has the same lighthearted, silly tone. The robotic cat will overturn all grim and gritty conventions! 2. There may be lots of references, as well as out-of-character moments and stereotypes. 3. The villains will be tormented!!! I haven't figured out the ending yet. Some of them will probably die, though Doraemon is just a kid and won't be the one who kills them. They might also be thrown into ancient times to live as cavemen, where they'll be made to start over! Theme: Love and peace
