Welcome back to Chapter 2 of Joined Worlds. I hope you enjoyed the first chapter, and if you didn't, well, then maybe you will enjoy how I ramp things up this time. Anyways, back to where we left off…

"Eggman, you aren't gonna get away that easily!"

Team Sonic was close on Eggman's tail, while he applied maximum speed to his Egg Mobile, trying to flee. But the only reason he hadn't been caught yet is because he had the advantage of flight. Sonic's speed allowed him to keep up, but lacked the reach he needed. And because the majority of his base hadn't been rebuilt yet, there were no structures for him to use for gaining height.

"Those little pests have no idea what they're in for" Eggman thought wickedly. While those fools were giving chase, they were running straight for his trap. He glanced up, looking at the structure he was flying for.

"The one thing that has been completely finished in the ruins of Eggmanland is my main base, which was good thinking on my part" he thought. "Once I lure those idiots inside, I'll reveal my secret weapon to them. I saw them coming, those Chaos Emeralds lit up my radar like a Christmas tree."

Eggman had been working on something himself for the past few months, and had devised the perfect plan to wipe Team Sonic out.

"Once they're inside, those emeralds they have on them will be as good as ours, and afterwards, well, let's just say that it will be a very chaotic end!"

Minutes later, out front of the Eggmanland Tower Base…

Sonic and his friends watched as Eggman flew into one of the upper windows of his complex, disappearing out of sight. The hatch shut behind him, leaving no open roads into the base.

"Well isn't this just great?" Knuckles shot at Sonic. "You let him get away, Pin-cushion."

"Hey, don't blame me Mr. Blame Game" Sonic launched right back. "How did you expect me to jump a hundred feet into the air and bring Eggman down? If anything, you should've ran ahead and caught him. I may have been faster than him, but he was slower than you! You could've scaled the tower and locked him out!"

"Are you even listening to yourself, you self-righteous little-?"

"ENOUGH, YOU TWO ARE DRIVING ME CRAZY" yelled Tails. "CAN'T YOU BEAR TO GET ALONG WITH EACH OTHER LONG ENOUGH TO FINISH ONE MISSION?!"

Now, both Sonic and Knuckles were silent, and staring at Tails open jawed. Never had the heard such a verbal assault come from the sweet-minded orange fox. And after the initial shock of all of that coming out of Tails' mouth, they heard the sense behind the words. They both felt ashamed of themselves and mumbled out a quick "sorry" to each other, then proceeded to take great interest in their shoes.

"Okay, now, we need to find a way into that base" Tails said as he shot a quick glare at the hedgehog and echidna.

"Well, I could always try using my shovel claws to get though the main door" Knuckles proposed."

"I could probably drill through the door as well with my Spin Dash" Sonic added.

"Both are good ideas. I'm going to add to it too. You guys try your digging and grinding on the wall, but first, I'll detonate an explosive charge on the door. That should weaken it if not blow it wide open." Tails delivered his plan to the others.

"All right, we aren't moving from this spot until we make our way inside!" cheered Sonic.

"YEAH!" shouted the other two in unison.

Back over on Earth…

"This isn't good"

No sooner had the words left Goku's mouth, than did he realize how redundant they were. When is there ever a good scenario involving the fabric of reality tearing like some maniac slicing through a curtain with a knife?

Gohan rushed down beside his father to examine these rips in the universe. After a quick look, Gohan said "Well Dad, I do have just a little hunch on how this happened."

Goku turned towards his eldest son in hope. "That's awesome Gohan, what do you think is going on?"

Gohan closed his eyes and put on an almost meditative look on his face. Then, without turning his head, he answered, "Well, in the short theory, Buu."

"WHAAAAAT?" Goku shouted in surprise. "But Buu has been completely reformed, and besides, I would sense if Buu had gotten angry enough to do this."

Gohan opened his eyes and turned towards his father with a serious expression on his face. "Dad, I don't mean the current state of Buu. But from what you said…"

Flashback

Super Vegito hovered over the ocean, facing Super Buu, who had absorbed Gohan. Buu felt a severe hatred for this challenger, who had come out of nowhere and made him, the terror of the universe, look like some odd bystander in terms of power. He could feel anger boil up inside him, and he felt his power rise with it.

"GWAAAAAAAAAAAUUUGGGGHHHHHH!" he screamed. Super Buu's anger had pushed him over, and he began to scream with such ferocity, that the dimensional walls began to crack, split, and falter.

"Hrrgh, I can't let this go on" Vegito decided. With his mind made up, he launched himself at Buu, pushing with all of his might, until he got through the energy surrounding Buu, and struck him hard enough to knock him out of it.

Super Buu fell down into the ocean, and the splits in the air began to close, and had just finished closing when Buu popped his head up.

Flashback End

"Anyways, based on your account of that moment, it seems that the evil version of Buu attempted to destroy you by splitting dimensions. However, even though they sealed back up, it could've left the dimensional walls unstable, so if another event happened to affect them, they may collapse." Gohan finished his theory.

"AAUGGHH, this is terrible, isn't there anything we can do?" Goku asked in frustration.

"That's what I'm thinking about Dad, but unless we can find what's causing the split, there's not much we can do. And while this could be catastrophic, it's not as bad as you may think."

"Huh?" Goku wondered.

"When, sorry, if the walls collapse, then it won't mean anything like the end of reality. More than likely. Most possibly what might happen is whatever wall is breaking down, whichever world is on the other side, our two worlds will likely merge together."

"Well then, we'd better hope that it's a good world on the other side." Said Goku.

"What I'm wondering, is what could be causing this disturbance? It's all so strange, but if only I knew the source…"

Back on Mobius

BOOM!

"*Cough, *cough, see guys, nothing a little bit of firepower can't break down." Tails wheezed out. The explosion had been a bit more than he had thought, so when it went off, he got the wind knocked out of him.

Sonic stepped into the now open doorway into the base. At first glance, nothing seemed wrong. As he walked further in, the other followed him. They were about 20 feet in when the heard a loud SLAM behind them. They looked back to discover the door they had blown open had just been replaced with a reinforced metal gate.

"Well, something tells me that we're not getting back out that way." Sonic said. This new door looked a lot heavier and more solid then the last door they had gone through, which Sonic looked back on as suspiciously flimsy.

"Come on guys, let's move on ahead, because we obviously can't go back." Tails said, leading the group down the hall.

After the first 5 minutes, they started encountering little scuffles with various guard robots, but they were dispatched of easily.

Eventually, after about half an hour, they reached a large door at the top of the tower. They pushed it open, and as it opened, they were met with a scene which they did not expect.

"Shadow?"

Before them, was Gerald Robotnik's greatest creation, the Ultimate Life Form, Shadow the Hedgehog. He didn't even look back towards them, but they knew he had heard them.

But the real surprise was lying in front of Shadow. Eggman was standing on a platform connected to a massive cannon-like machine at the far end of the room. From the angle they were at, they could see inside the barrel, and noticed 3 Chaos Emeralds inside.

"What's he planning?" Sonic wondered.

"Perfect" Eggman thought. "You all have fallen right into my trap!" he gloated. "Now watch this. CHAOS MAGNET ACTIVATE!"

Immediately, a pulse came from the machine Eggman was standing on, and less that a second later, a Chaos Emerald was flying towards it from Sonic, Knuckles, Tails, and Shadow! All 4 emeralds locked themselves into the barrel of the cannon with the 3 others.

"Heh heh heh. Heh Heh Heh, HO HO HO HO!" Eggman reveled in his machine's success.

"Just what are you playing at Egghead?" Sonic challenged.

Eggman glanced down at him. "It's time I show you what happens to those who annoy me enough!" he shouted. And with that, he hit a button on the machine, which aimed itself at the group of 4 standing in front of Eggman.

"Now then, prepare to feel my wrath you meddlers. You will now see my full fury!"

"What's going on?" Tails asked in a meek voice.

"Tails, RUN!" Sonic yelled, and started to dash for the exit as well, only to find it had closed them off.

"No, I, it, it's over!" Sonic stuttered.

"Yes it is, Hedgehog. Now…" Eggman paused.

With a sudden motion, Eggman hammered a button on the machine.

"CHAOS CONTROL CANNON, FIRE!"

So here is the end of the second chapter. This one mainly focused on Team Sonic's chasing after Eggman, though we did flash over to Goku's side and learned a bit about the possible cause of the dimension rifts appearing on his side. Prepare yourself for the breakdown of the dimensions, and in the meantime, please review, as this is my first story, and feedback is greatly appreciated.
