So! Amity Park is a hub of weirdness of all sorts, mostly undead, but there are also a bunch of Multiversal oddities connected to the small town.
There are the minor anomalies. 5th Street has a bad habit of slipping into the Backrooms, Old Lady Jenkin's House sometimes has snow in summer, and of course the Night Sky had a 20% chance of swapping views to another Galaxy. Danny likes that one a lot.
But the biggest Anomaly is how many Multiversal Travellers get lost there.
They are always finding somebody wandering the streets with no idea where they are, and have to help them find their reality of origin. Other times they decide to stay for various reasons, ranging from a bad home life to being the only survivors of a Dead Universe. Half of the population if Amity was made up of the descendants of Lost Travelers, so their DNA was really a mixed bag.
Danny was flying over town when he spotted a Blur on the ground below.
He flew down to intercept, and found a boy in red and yellow panicking over his situation.
"Hey! Can I help you?" He called out.
The boy looked up, and gasped "Are you a Hero? I need help getting back to the Justice League!"
Danny chuckled, "Which one?"
The boy looked confused, "The Adult One? I guess?"
"Not what I meant, sorry. I mean, which Dimension are you from?" He clarified.
"Dimensions? What is going on!?" He shouted.
"Okay, let's calm down and restart. My name is Danny, who are you?" He introduced himself.
The boy took a deep breath, calming himself, before saying, "Okay, my name is Kid Flash, but you can just call me Wally."
