Late night reading
Twilight Sparkle is asleep in her bed when she's stirred awake by a lamp switching on. She sees Spike reading a comic book and tells him to go to sleep, but Spike asks for two more minutes. He proceeds to talk at length about the Power Ponies, their sidekick Humdrum, and the evil Mane-iac. Twilight sympathizes with Spike's investment in a book, but states they'll need to be well-rested to help fix up Princess Celestia and Princess Luna's old castle in the morning. Spike relents and goes to bed, but when Twilight sees him fumbling in the dark for his comic, Twilight allows him two more minutes to read.

Diving into a comic
The next morning, Twilight and her friends take part in refurbishing Celestia and Luna's old castle. Spike wishes to pitch in, but the ponies politely decline. Twilight tells him to find someplace quiet to read his comic, and Spike shuffles off, feeling useless.

Spike goes to Celestia and Luna's reading room to read, sympathizing with the bumbling Humdrum. When he suddenly reaches the end of the comic, he finds a footnote in small, hard-to-read text. As Twilight and the others take a break from cleaning and come looking for Spike, he uses a magnifying glass to read the footnote: "You can return to the place you started when the Mane-iac is defeated. Take a closer look to join the adventure in this book." This causes a magic in the comic book to surge to life, and Spike is sucked inside its pages. Twilight and her friends, in their attempt to save him, get dragged inside as well, except Pinkie who just jumps in after them.

Welcome to Maretropolis
Spike, now in superhero attire, regains consciousness on the roof of a building in Maretropolis. Behind him, he sees his pony friends in superhero attire as well and recognizes them as the heroes in his comic—the Power Ponies.

Suddenly, there's an explosion at the museum across the street, and the Mane-iac emerges from the smoke, laughing maniacally and holding an orb surging with electricity. When Applejack and Rainbow Dash wonder what's going on, Spike explains that they were transported into his comic book and that the only way out to defeat the Mane-iac. The Mane-iac attacks the ponies with a pretzel cart and a mailbox; as Pinkie Pie dodges the mailbox, she demonstrates the super speed of her Power Pony persona Fili-Second.

Applejack tries to wrangle the Mane-iac with her lasso, but it works against her, and she pins herself to a lamppost. Twilight's attempts at using the Masked Matter-Horn's powers fizzle, Rainbow Dash uses Zapp's powers to create a tornado instead of lightning, Rarity's powers as Radiance prove less than helpful, and Fluttershy's anger-based powers as Saddle Rager don't manifest because she's not angry. After watching in amusement, the Mane-iac takes her leave, but not before addressing Spike by his designated role as Humdrum.

Applejack reins in the tornado with Mistress Mare-velous' powers, and Spike once again explains to his friends that the only way out of the comic book world is to stop the Mane-iac from using her doomsday device. While Rainbow Dash is excited about having superpowers, Spike is less than thrilled about being the powerless Humdrum. Twilight encourages Spike by saying he's not really Humdrum, but he is still in low spirits.

Time to Power Pony up!
Spike leads the Power Ponies to the Mane-iac's headquarters: her shampoo factory. Before Twilight can come up with a plan, Rainbow Dash gives away her and her friends' position by zapping the building with lightning. As Spike stays back, the Mane-iac's henchponies emerge from the factory and attack. Despite Fluttershy's inability to get angry, the Power Ponies subdue and restrain the henchponies.

When the Mane-iac herself appears, she immobilizes the Power Ponies with her "hairspray ray of doom". She leaves Humdrum behind, considering it pointless to use her spray on him. Spike watches helplessly as the Mane-iac and her henchponies take the Power Ponies prisoner.

The sidekick saves the day
Spike sneaks into the factory through an air duct, all the while cursing his own uselessness, and finds his friends still immobilized and inside a big cage. Each time the effect of the spray wears off, one of the henchponies sprays them again.

The Mane-iac uses the Electro-Orb to power her hair dryer-shaped cannon, and tells the Power Ponies her plan to use it on them and the citizens of Maretropolis and cause their manes to grow wildly. When Fluttershy reminds her of Humdrum, the Mane-iac once again dismisses the little guy as useless. The Power Ponies disagree, with Twilight noting that in their world, he always comes through.

Encouraged by his friends' words of praise, Spike springs into action. As the Mane-iac monologues to the ponies in true villain fashion, Spike ensnares some of the henchponies in a large tarp and immobilizes more with the Mane-iac's hairspray, allowing the Power Ponies to break free. The ponies fight off the rest of the henchponies as the Mane-iac powers up her cannon. When a firefly gets in her line of fire and she swats it away, Fluttershy loses her temper, and the powers of Saddle Rager finally manifest, turning her into a large, muscular monster.

The Mane-iac fires her weapon at Saddle Rager, but its beam bounces back at her, and Saddle Rager smashes the weapon to pieces. The effects of the weapon entraps the Mane-iac in her own mane like a straitjacket. Spike declares the Power Ponies victorious, and he and the ponies are transported away.

Epilogue
Spike and the others are transported out of the comic book and back into Celestia and Luna's old reading room. As the ponies shake off the excitement of their latest adventure, Pinkie Pie offers the group cupcakes, which she picked up from the Maretropolis Bakery a half-second before their return home. Twilight commends Spike for his heroism, and Spike learns that he doesn't need superpowers to be a super friend.

When Twilight asks where Spike got the comic book, he says he got it in a store in Canterlot that sold "enchanted" comic books, not realizing that the comics were magically enchanted as opposed to telling enchanting stories. The ponies and Spike leave the room, and the comic book suddenly vanishes in a flash of white light.

Superhero theme
This is the show's second superhero-themed episode following The Mysterious Mare Do Well in Season 2. The references include:
 * The Mane-iac's origin involves falling into a vat of chemical liquid is similar to the Joker's origin in the 1988 graphic novel Batman: The Killing Joke (which was incorporated into the 1989 film Batman).
 * The Mane-iac's origin also involves being electrocuted by a downed power line, which is similar to Two-Face's origin in Batman: The Animated Series.
 * When Spike sees the Mane 6 in their costumes, he says, "Holy new personas, ponies!", which was a running gag used by Robin in the 1960's live-action Batman series.
 * Spike's Humdrum costume has a color scheme similar to that of Robin's.
 * Saddle Rager's (Fluttershy) anger transformation ability is similar to that of The Incredible Hulk.
 * Fili-Second's (Pinkie Pie) superpowers and costume are similar to that of the Flash.
 * The comic book setting is named "Maretropolis", a clear play on the city of Metropolis in the Superman comics.
 * Mistress Mare-velous (Applejack) wields a lasso similar to that of Wonder Woman.
 * Zapp's (Rainbow Dash) powers are based on those of Thor and Storm.
 * Radiance (Rarity) has creation powers similar to those of Green Lantern, although the color of her constructs is the same as that of the Star Sapphires, another group from the Green Lantern stories.
 * Masked Matter-Horn (Twilight Sparkle) has powers loosely based on those of Cyclops of the X-Men, although they are more varied in effect.
