In Lori’s Nightmare on Roblox, you cannot manually choose or change your role during a round.
Your role—Child or The Nightmare —is assigned automatically by the game at the start of each round, and it stays that way until the round ends.

Quick answer

  • You can’t change your role mid-round.
  • You can influence your chances of getting a certain role by playing more rounds and using coin/Robux boosts, but the game still decides who becomes The Nightmare.

How roles work in Lori’s Nightmare

Automatic role assignment

When you join a round:

  1. The game loads the server.
  2. One player is randomly chosen as The Nightmare.
  3. All other players become Children.

This is part of the core 1‑vs‑many horror mechanic: one monster hunts, the rest try to survive and complete objectives (restore the TVs).

What you can actually customize

You can change:

  • Your character (Child skin) – not your role.
    • In the spawn/start area, click the “Children” button on the left.
    • Scroll through the list, pick a character, and buy it with Coins or Robux.
  • Your in‑game abilities – some characters have different speeds or perks, but all are still “Children” unless the game assigns you as The Nightmare.

You cannot:

  • Open a menu and select “I want to be The Nightmare now.”
  • Swap roles with another player while the round is running.

Ways to influence your role (sort of)

While there’s no direct “change role” button, players often try to:

  • Play more rounds – more rounds = more chances to be randomly assigned as The Nightmare.
  • Use boosts or items from the shop (if available) – some horror Roblox games let you buy items that slightly increase your chance of getting the monster role, though for Lori’s Nightmare the guides mainly mention buying coins/characters, not explicit role boosts.

Even then, the final decision is still random and controlled by the game.

If you meant “community roles” (not game roles)

If your question was about Roblox community/role ranks (Owner, Admin, Member, Guest, custom roles) and not the in-game Child/ Nightmare roles:

  • Only community owners or higher-ranked members can change other members’ roles.
  • You go to:
    Community → Configure Community → Members → drop‑down under a user → select role.
  • Custom roles cost 25 Robux each and must have unique names and ranks.

But this is about group permissions , not Lori’s Nightmare’s Child vs Nightmare mechanic. In short: in Lori’s Nightmare gameplay, you cannot change roles yourself. You wait for the game to assign you as Child or The Nightmare , and you can only change your character skin, not your role.
