I had a idea of this in my head and thought I would make it. These are the characters in the story. I decided to use the LEGO Ultra Agents' villains in my story. I hope you all enjoy it!

Earth-77

On this Earth in the Multiverse, it's the monster apocalypse, and the only people left on Earth are four 13-year-olds. They're somewhat of a motley crew. Main character Jack is an enthusiastic, slightly awkward video game enthusiast. The rest of the team is rounded out by Jack's nerdy scientist best friend, Quint; brave ex-newspaper editor June, and reformed school bully Dirk. As the characters say, "It's the end of the world. No rules. No bedtimes." The kids live together in a tree house and navigate typical middle school issues like disagreements with friends, crushes, and trying to fit in. They're also trying to slay the monsters that have taken over the world, and they go on heroic adventures to fight them. Since no grown-ups survived the apocalypse, they live a version of every kid's fantasy, with as much video games and junk food as they want.
