HIM enters the girls dreams and turns them into nightmares.
Power Noia contains examples of:
- Battle in the Center of the Mind: The conflict between HIM and the girls takes place entirely inside the girls' dreams, and thus their heads.
- Clipped-Wing Angel: HIM assumes a truly monstrous form before confronting the girls himself, but it doesn't do him any good as they beat him to pulp just as easily as they usually do.
- Creepy Monotone: The children in Ms. Keane's class speak this way.
- Darker and Edgier: It's an episode with Him as the villain and it focuses on nightmares, you do the math.
- Dream Walker: HIM when he enters the girls dreams. The girls themselves later on when they escape their own nightmares and team up in a Shared Dream.
- Living Toys: These show up in Bubbles' nightmare.
- Nightmare Sequence: A good portion of the episode focuses on the girls' individual bad dreams.
- Series Continuity Error: This episode shows Buttercup being afraid of bugs, but this contradicts the season 1 episode Insect Inside where it was Bubbles who is terrified by a cockroach while Buttercup only considers the bug gross but not terrifying.
- Shared Dream: The girls are given nightmares by HIM until they escape their individual dreams and team up in a shared dream to take HIM on
- Spiders Are Scary: Buttercup certainly thinks so, and her nightmare reflects this.
- To the Pain: The Him!dolls in Bubbles' nightmare take sadistic glee in describing how they're going to turn her into a toy herself.
- "What Do They Fear?" Episode: Blossoms nightmare is about her failing an important test at school, Buttercup about getting trapped in a room full of bugs, and Bubbles about her toys coming to life and turning on her.
