Amy held up her mallet threateningly, eyeing the aliens as they slithered closer. Suddenly, she placed the mallet down and turned to the side.

"Hey, if any little kids are reading this, you may want to skip a bit until Shadow returns, okay? And if you aren't a little kid and hate one sided fights…Go buy some novels at a video game store or something', k?" Amy said sweetly, then narrowed her eyes at the aliens.

-Note! The author has gone off to buy novels at a video game store, so the next part was written by his cat.-

Meow!

-Truly breathtaking. What's this? I've just found out I've been sacked. The actual fight scene will be written by Knuckles, who's wondering why he has yet to appear in any of the Captain Underpants stories yet.-

Okay…There Amy was, the three aliens coming at her. Normally I'd think she was a goner, but Amy's been getting stronger lately, and these aliens? I don't think they have spines, both literally and figuratively.

On with this fight…Wow! Xtry didn't expect that! Oh…What an underhanded blow! Even Rouge doesn't fight that dirty. I better be more careful around Amy.

Man! What a spectacular fight! You guys reading this should see it. I can't describe it…Wait…It's over!

-We now return you to your regularly scheduled author.-

Shadow Underpants reappeared, dress in a red cape and tidy whities, beaming proudly as he looked at the beaten and bruised forms of the aliens.

"What took you so long?" Amy demanded, placing her mallet into it's hammerspace and staring at Shadow.

"I was off with the author buying novels at a video game store," Shadow answered. Amy merely stared.

"Ooookay…Let's just find out what we can from these aliens," Amy said, pulling up Bob by his 'throat' and staring at him. "Okay, fess up, how can we get everyone back to normal?"

"I shall never tell you earthling scum!" Bob shouted, waving his tentacles at Amy and Shadow Underpants.

"Wrong answer!" Amy yelled, holding her mallet up with her free hand.

"Silly earthlings! Mallets are for ALIENS!" Bob suddenly shouted, confusing even the hypnotized Shadow. He pressed something on his belt device and trapped Amy and Shadow in a force field bubble!

"The fiends!" Shadow shouted, punching at the bubble but not destroying it.

"Shadow! We don't have time for this! Chaos Control us out or something!" Amy yelled, as Bob lifted the bubble with a handheld device and brought them to their ship.

"Who is this Shadow everyone keeps talking about? I'm Captain Underpants!" Shadow shouted, posing heroically.

Amy sighed as the bubble was displaced, having placed the two in a cell inside the ship. The ship rumbled and took off into the sky…

"Okay! Now that these Earthlings have been dealt with, we'll introduce the Super Powered Juice into the storm we're also creating, showering our loyal zombie nerds with the juice and we shall take over this puny planet!" Bob cackled madly, looking into the fridge which was conveniently right by the prison bars.

Amy and, and surprisingly Shadow Underpants were thanking fast, looking at the fridge while the aliens had their backs turn in a group evil laugh.

The pink hedgehog reached through the bars and opened the fridge carefully, taking the Super Powered Juice and the Explosive Juice out, then switching the labels. With a thought, she kept the Super Powered Juice for herself, hiding it.

"Ktry! Get the Super Powered Juice and load it into the cannon!" Bob ordered. The alien complied and pulled out what was labeled 'Super Power Juice', but really the Explosive Juice.

"Shadow…hold on to something…" Amy directed, Ktry loading the Explosive Juice.

Bob hit a button and their was a rumble, then a large explosion, rocking the ship, blowing up it's top as the three aliens screamed, jumping out and using their versions of parachutes.

"Excellent! Now what's your plan for escaping this crashing ship?" Shadow asked Amy as the ship crumbled apart, the two hedgehogs now free falling.

Amy blinked, thinking thoughtfully.

"You don't happen to have a glass of water on you, do you?" Amy finally asked. The underwear clad hedgehog shook his head no.

Amy frowned again, then looked at the approaching sky scrapers.

"Then we're screwed," Amy said, shaking her head slightly.

"Not necessarily!" Shadow shouted, pulling out a roll of…FOUR PLY TOILET PAPER!

"Why is it shining?" Amy wondered as Shadow grabbed her and threw the toilet paper as they came across the sky scrapers, grabbing a flag pole and wrapping around it. It held for a second, slowing their descent, then they began to fall again…

Amy sweat dropped as they fell, then, in a sheer force of luck, stupidity, and plot holeness, the two hedgehogs fell into a pile of mattresses…

"These are eerily convenient placed mattresses," Amy commented, Shadow hopping off the said sleeping devices, Amy following him.

"And those zombie nerds seem to not be here," Shadow Underpants commented. "Perhaps Tails found a cure!"

"Or perhaps it is time to face your doom!" a familiar voice shouted. Twirling around, Bob, Ktry, and Xlater approached them, having survived thanks to their parachutes.

"I didn't want to do this, but you leave me no choice!" Bob yelled, pulling out a vial of juice and drinking it…

With a yell of ferocity, Bob grew, over five times his normal size, tentacles multiplying and becoming much more muscular.

"It is time for you two to perish!" Bob yelled in a much louder and lower voice, Xlater and Ktry hiding in the background.

With a shove, he grabbed Shadow and slammed him into a wall.

Amy froze, then sighed, pulling out the true Super Powered Juice.

"This is our only chance…Sha…Captain Underpants!" Amy yelled, running towards Shadow as Bob's tentacles removed themselves from the prone hedgehog and shot at Amy, who dodged the attacks, but barely.

"Okay…You're the only one who can defeat him!" Amy yelled, getting Shadow's mouth open and pouring in some of the Super Power Juice.

Shadow Underpant's eyes snapped opened as he stood up, healing thanks to both the juice and his natural healing abilities.

"Alright aliens! I am Captain Underpants, Defender of Truth, Justice, and all that is Pre-Shrunk and Cottony…TRA LA LA!"

Shadow, a.k.a. Captain Underpants, attacked…

0000000000

A.N. WOOO! Sorry for the long wait, been busy with school! Thanks for all the reviews!

Okay…Next part, Shadow Underpants fights the powered up Bob the alien! Plus, afterwards, the beginning of the next fight for Shadow Underpants.

Also…I have an idea for the next Shadow Underpants, once I finish up with this one. It shall be called, "Shadow Underpants: Will The Real Captain Underpants Please Stand Up?" Unless that's to long a title…Heh…

I do not own Sonic, Captain Underpants, and all related titles!
