Cinder-"(sniff) Papa, how could you!?"

Magma remained silent, 'till he realised something.

Magma-"Cinder, this is all your fault!"

Cinder-"WHAT!?"

KND and mobions-"WHAT!?"

Magma-"Because of you intervened, and look what happened: you made your brother get killed!"

Cinder-"Papa, how can you be so cruel?!"

One-"HEY! It's not her fault! You think that we are thieves but we are not, THEY are! (indicates The Delightful Children and Eggman)"

Eggman-"Magma, do not listen to those little pests, just tell your lava men to destroy them and get this over with!"

Magma-"With pleasure. (to the lava monsters) DESTROY THEM!!"

The lava monsters charge at the heroes, but they as usual, fight back. The KND use they 2X4 technology weapons and their new mobion abilities: Numbuh One uses Spin Attacks, Numbuh Two pounds hard with his large firsts, Numbuh Three uses her cat claws, Numbuh Four punches them hard on their heads and Numbuh Five flyies around them with her bat wings. With the mobions, Sonic uses his spin attacks and break dance style moves, Tails flies around them tossing dummy ring bombs on them, Shadow launches Chaos Spears at them and Amy blows them away with her hammer.

Delightful Children-"Aw come on! Can't these guys just finish them off already?!"

Magma-"I have a plan, but first…(turns to see Cinder, but she's gone)…huh? Where did she go?

Cinder-"Papa."

Magma turns and gasps to see Cinder with the Chaos Emerald in her hands. Eggman and the Delightful Children turn and gasp too.

Magma-"Cinder, put that emerald back in it's proper place!"

Cinder-"You'll have to catch me first! (flies off with the emerald)"

Eggman-"Oh no, you don't!"

Eggman pushes a button on his control panel and the rod under the Egg Mobile withdraws and a robot arm comes out from it's place. It stretches out and grabs Cinder by her leg.

Cinder-"(being dragged toward the villains) AAH! NO! I'M NOT GIVINGG YOU BACK THE EMERALD!"

Meanwhile, our heroes notice this and gasp in horror.

Amy-"Cinder's in trouble!"

Sonic-"Damn that Egg-face and those brats!"

Five-"Hmm, hey, Tails!"

Tails-"Yes Numbuh Five?"

Back with Cinder, Magma was now over her with an angry look on his face.

Magma-"Cinder, give me back our treasure, or else!"

Cinder-"No! I'd rather die at the hands of my own dad you doesn't even deserve to be a king!"

Eggman-"(bored) Man, that is one persistent little brat isn't she?"

Delightful Children-"(irritated) Enough of this! MAGMA, FINISH HER OFF!!"

Magma-"Pleasure. (points his hand at Cinders face, forming a fire ball) Good bye Cinder."

But before he could finish her off, Magma was suddenly attacked by a double kick surprise attack from Numbuh Five and Tails, causing him to be trust back onto a rocky wall.

Eggman and DCFDTL-"WHAT THE!?"

Numbuh Five then pulls out her laser rifles and blasts the robot arm with it, thus freeing Cinder from it's grip.

Eggman-"ARGH! HOW DARE YOU!!"

Cinder-"Thank you for saving me."

Five-"No problem kid-o."

Tails-"You're welcome."

Back with the rest, they were still fighting lava monsters and Shadow was getting pissed off.

Shadow-"That does it! The rest of you stand back!"

Sonic-"Uh oh!"

Four-"What do you mean 'uh oh'?"

Sonic didn't answer, he just simply grabbed everyone in a blue streak of light and ran as far away from Shadow. The black hedgehog began to glow in a red aura, while growling hard. From the safe place, the KND looked at this in curiosity.

Two-"What's wrong with him?"

Sonic-"Just take cover; this is going to be a blast!"

Back with Shadow, the lava monsters all charge at Shadow, who was still growling with the red aura over his body.

Shadow-"CHAOS…BLAST!!"

Upon shouting this, a large dome shaped blast expanded from around Shadow, that swallowed and destroyed the lava monsters. When the blast died down, all the lava monsters were gone, only Shadow stood there panting. The KND's jaws dropped in shock.

Three-"(from shocked to thrilled) That was COOL!! Do it again, do it again!"

One-"Amazing! How does he do that!?"

Sonic-"He, THIS is why he's called, the Ultimate Life Form!"

Two-"Wow!"

Back with Numbuh Five, Tails and Cinder, they all saw what Shadow did and only Abby and Cinder were shocked.

Five-"Wow, Ultimate Life Form indeed!"

Tails-"And it's quiet shocking that it was Egg-butt's grandfather who created him."

Eggman-"WHAT DID YOU CALL ME!!"

Cinder-"Uh oh."

Eggman drives the Egg Mobile toward the flying heroes. Tails flies back to the others, followed by Numbuh Five who was embracing Cinder to keep her and the Chaos Emerald safe. Magma then appears in front of them, but they don't stop.

Magma-"Halt! (but they fly right past him) I said halt! (gets flown over by the Egg Mobile) OUCH!

Five-"Come on guys we are out of here!"

Two-"What about the Chaos Emerald?"

Cinder-"Don't worry, I have it. (shows the emerald) See?"

Sonic-"Great, now let's get out of here!"

Sonic grabs Tails and Amy by their arms, while Tails was holding Numbuh Five, who was holding Cinder, who was holding the Chaos Emerald; and Amy was holding Numbuh One, who was holding Numbuh Two. Shadow grabs Numbuh Four and Five by their arms. As they were set, they raced off to the exit as fast as they could.

Magma-"No! They are not taking my emerald away!"

But before he went after them, Eggman and the Delightful Children intervened.

Magma-"What is the meaning of this?!"

Eggman-"Sorry to disappoint you Magma but…"

Delightful Children-"We don't require your services anymore!"

Magma-"Huh?"

As a response, Eggman pushed a button on the panel that shot a large laser beam from the headlight, which swallowed and killed Magma, reducing him to ashes. After that, the whole place suddenly began to rumble.

Delightful Children-"(evil sneaker) Now let's see how those pest can get out of this one!"

The evil genius and the delightful children began laughing maniacally as they drove the Egg Mobile into the hole they came in through, before the chamber they were in crumbled on top of them.

Meanwhile, the KND and the mobions were still running down the tunnel when they heard the rumbling sounds.

Amy-"What's going on?!"

Tails-"The volcano's about to erupt, we have to get out of here quick!"

Sonic-"Don't worry guys here we go!"

With that, Sonic speed boosts into a blue streak of light, with the ones he was carring screaming at top of their lungs. Shadow does the same thing with Numbuh Four screaming like a little girl, but Numbuh Three was actually enjoying it. Soon they all got on board the H.O.T.S.H.O.T. and Numbuh Two and Tails drove it down the lava cave as they avoid any falling stalagmites from the cave ceiling. Everyone got inside as they dive the vessel into the rising molten lava.

Five-"Guys! Temperature is rising at a catastrophic speed! This place is going to to blow sky high!"

One-"Numbuh Two, pick up the pace now!"

Two-"Roger that!"

Numbuh Two pushes the speed lever to the max as everyone braces themselves from the speed. Soon after, the ship sailed right up into the surface whish caused it to fly up the air and crash on a rocky ground, which was luckily outside the volcano, causing the vessel some damage. Inside..,

Sonic-"Is everyone alright?"

Tails-"Yeah, we're fine."

One-"Come on, let's get out of here!"

Everyone walked out from the damaged vessel, some a little bruised and stuff, but luckily, they were okay. As Numbuh Two changes the H.O.T.S.H.O.T. back into a capsule by pressing a small button on it, Cinder walked over to the edge of the rocky mount just in time to see the volcano erupt and break down to bits. The tiny bat sighted in sadness about this whole thing as a tear run down her cheek.

Cinder-"Why…why did this have to happen?"

Numbuh Five walked over to her and placed her hand over her shoulder. Cinder looked at her with a soft smile on her face.

Five-"It ain't your fault Cinder, Eggman and the Delightful Children did this and they are going to pay for this."

Tails-"Yeah Cinder, I'm also sure he also didn't mean to kill your brother. But now, that's all in the past, just let it go."

Cinder-"Well…alright. (cleans off her tears)"

Sonic-"That's better."

One-"(to his teammates) Well Team, I have to admit, that was the most cruel parent I had ever seen in my entire life, not to mention that he had allied with the Delightful Children and Eggman."

Two-"Yeah Numbuh One, I still can't believe he had actually ended up killing his own son."

Four-"Who was teenager too!"

Three-"If only he was better, he would have sure survived."

One-"To tell the truth Numbuh Three, I would doubt that, cause the Delightful Children and Eggman helped him out too."

Everyone lowered their heads I disillusion about everyone that happened until now.

Cinder-"Now what will become of me? My family is dead, my kingdom is destroyed…"

Sonic-"I know! Why don't you come with us?"

Cinder-"(shocked) You really mean that?"

Sonic-"Hedgehog's honour, right guys?"

Tails-"Yeah!"

Amy-"She can come with us!"

Shadow-"Hmph, whatever."

One-"Yeah, okay, as long as she can hold herself well in combat."

Four-"Hmm, yeah, it's okay."

Three-"YAY! We get a new friend!"

Two-"Totally."

Five-"Yeah and don't worry, we won't anything bad happen to you."

Cinder-"Thank you…um, what were your names again?"

Sonic-"I'm Sonic, Sonic the Hedgehog!"

Tails-"My name's Miles Prower, but you can call me Tails!"

One-"I am Numbuh One, leader of Kids Next Door Sector V!"

Two-"I'm Numbuh Two, the mechanist of Kids Next Door Sector V!"

Three-"I'm Numbuh Three, the nurse of Kids Next Door Sector V!"

Amy-"My name is Amy Rose!"

Shadow-"Hmph, I'm Shadow the Hedgehog, the one and only Ultimate Life-Form."

Four-"I'm Numbuh Four, expert in hand-to-hand combat of Kids Next Door Sector V!"

Five-"I'm Numbuh Five, the second-in-command of Kids Next Door Sector V!"

Cinder-"Nice to meet you all! I promise you won't regret this, I'll do everything necessary to help you find the Chaos Emeralds!"

Soon after, they found the Tornado standing of top of a rock road waiting for them. They climb on to it and fly away into the sky.

KND Computer- "Chaos Emerald count: 5. Only 2 left to find."
