A.N. Sorry for the long update! I got no reviews. No reviews greatly saddens me, so you'll review this time, right?

"Hmmm…It seems Amy followed the opposite of what Sonic told her so…" Tails said, peering at the dearmored and tied up Amy at the chair, the 3-D Hypno Ring on his finger, Shadow Underpants holding up an underwear to fire, just in case.

Tails waved the 3-D Hypno Ring in front of Evil Amy, putting her in a hypnotized state.

"Okay…You will remember being evil. You will not become good. You will remember Shadow becoming Captain Underpants, and you certainly won't bake us cookies tomorrow, and you won't fall asleep when I snap my fingers," Tails said, snapping his fingers. Amy fell asleep.

"Okay, I'm going to get Amy back to her apartment. You watch Sonic," Tails said, freeing Amy, and using some miscellaneous machine to carry her off.

"So I shall!" Shadow Underpants shouted, jumping upwards and landing on the top of the couch where Sonic was laying, still out like a light. He crouched like a vulture and stared blank eyed at Sonic.

A few minutes later, Sonic stirred, opened his eyes, and screamed when he saw Shadow Underpants staring over him, flying off the couch and clinging to a fan on the ceiling.

"Damnit Shadow! Don't scare me like that!" Sonic shouted, jumping downwards.

"I'm not Shadow. I'm Captain Underpants!" Shadow Underpants said, striking a pose, the falling off the back of the couch.

Sonic rolled his eyes and headed to the faucet. Time to bring back Shadow…

It was later in the day as Shadow, Sonic, and Tails sat about the living room, sipping lemonade and watching a movie.

Shadow, who had long ago learned it was pointless to try and get an explanation out of Sonic and Tails for the weird things had happened, studied the movie carefully.

"I don't get it…How are a yellow sponge and pink star supposed to be able to walk and talk? And a Plan Z? Hah! Why does he not simply use a Chaos Control to steal a 'Krabby Patty'?" Shadow demanded to know.

"It's a movie based on a kid's show…Deal with it," Sonic muttered, trying to enjoy the movie over Shadow's constant questions.

Afterwards, the three had dinner, and Shadow stuffed Sonic into the fridge for some reason. All in all, a typical day.

"Cookies?" Shadow wondered, the next day as Amy had appeared, with a tray of cookies. "Odd…You, know. I had a nightmare last night where you turned evil…"

Amy merely stared at Shadow and pushed her way inside.

"I baked cookies for you guys! Chow down!" Amy said. Sonic and Tails instantly appeared, and the cookies were gone in a second.

"You know…I wanted one of those…" Shadow muttered, picking up a crumb and placing it in his mouth. It just wasn't the same.

"Now for some milk!" Sonic said, dashing to the fridge, where a scream was heard.

Shadow, Tails, and Amy shared a glance, then headed to the fridge, where Sonic had fainted, the fridge door open, shining it's light on the prone hedgehog.

"Bartholomew?" Tails squeaked, wondering if that pranking penguin was back.

Tails glanced into the fridge, and gasped as well, and fainted, after he uttered two words.

"No milk…"

Shadow wondered why ominous music played, while Amy palmed herself in the face.

"Come on Shadow. This has happened before. We need to go get some milk to wake them," Amy sighed, stepping over Sonic and Tails, closing the fridge door then heading back.

"But where are we going to find a cow in the city?" Shadow wondered.

Amy faltered, nearly falling, "Shadow…don't take those picture books so seriously."

Shadow followed Amy curiously, wondering where they would procure this milk, were it not from a cow.

Finally, making it to the store, he paused. Something was familiar about this place, even though he could have sworn he had never been here before…Something else was telling him to run, though he suspected it might have been his morning's breakfast of burnt fruit smoothie.

Following Amy to the fridge section, Amy opened it up and pulled out a gallon of milk. Shadow stared in amazement.

"They have a cow back there or something?" Shadow wondered, trying to peer to the other wall.

"No Shadow…Look, I'll explain later. First we need to go pay," Amy answered. Nodding with a confused look in his eye, Shadow followed after Amy as they headed for the counter.

Amy muttered as she pulled out some money for the milk, Shadow standing in the background. They suddenly heard a clatter, and to everyone's amazement, evil laughter.

"Foolish mortals! No one can defeat me! I am the OctoMan!" a voice sounded. Shadow and Amy turned around slowly, seeing a strange man dressed in what appeared to be an octopus suit.

"I'll take care of this," Shadow sighed, cracking his knuckles and stepping forward.

Of course, we all know what comes next…

"Alright, give me all your scented towelettes, a bag of oyster skins, and some soda!" 'OctoMan' shouted, "And make it snappy!"

With this, the 'villain', snapped his fingers, as a change came under Shadow.

With a triumphant cry of, "Tra la laaaa!" Shadow Underpants bounded off quickly.

"Shadow! Where are you going?" Amy demanded. Her answer was soon given, as Shadow, now sporting a red ape, tidy whites, and an opened package of underwear under his arm came bounding back into view.

"Halt evil villain! In the name of Truth, Justice, and all that is Pre-Shrunk and Cottony!" Shadow shouted, posing heroically.

Amy sweat dropped, palming herself in the face and growling, "Shadow…what's gotten into you? Everyone is going to start laughing now…"

"Who is that mysterious hedgehog?" a customer asked one of the cashier workers.

"I don't know, but it looks like he's come to save us all!" the cashier said, everyone looking at Shadow in awe.

"I am Captain Underpants!" Shadow yelled, Amy now on the ground twitching at the stupidity of the population.

"Fool! You'll never defeat me!" OctoMan shouted, charging Shadow.

With yet another heroic cry of, "Tra la laaaa!" Shadow jumped on OctoMan's head, pulled out a spare piece of underwear, and shoved it over the villain's head, blinding him as he smashed into a pile of canned calamari, a cruel, yet ironic faint.

"And the day is saved again!" Shadow Underpants cried triumphantly.

"You're coming with me!" Amy growled, grabbing 'Captain Underpants' by the cape and dragging him off, taking the paid for milk with her.

"Go ahead and keep the underwear Captain Underpants!" the cashier shouted, waving happily to the hero, everyone giving a wild cheer of joy.

"Ah, good day! Are you dragging me through the gutter to show your appreciation of me? 'Cause if you are, that's an odd way to show it," Shadow said, Amy dragging him back to the apartment.

"No. I'm bringing you back to Sonic and Tails and getting this sorted out! Honestly Shadow! What's gotten into you?" Amy demanded, getting a few stares as the pink hedgehog dragged the Ultimate Life Form to an apartment building, then into an elevator, and eventually the apartment where Sonic, Tails, and Shadow lived.

"Ma'am, I am Captain Underpants. Not this 'Shadow' who you speak of," Shadow said, shaking his head as he was plopped unceremoniously unto Shadow's favorite chair.

Amy just sighed again and headed into the kitchen, using the milk to awaken Sonic and Tails from their cookie induced comma.

"Uh, hi Amy!" Shadow heard Sonic say from the kitchen. "You look kinda mad…"

"You two have a lot of explaining to do…" Amy growled, the Ultimate Life Form distinctly hearing a swish of mallet threatening.
