A/N: Sorry about that delay, but it is almost Christmas so I had to be ready. Here is the Pikachu chapter.

Chapter 7: Pikachu:

Pikachu just arrived to see Lucario was about to kill Yugi when Luffy punched Lucario sending Yugi free.

"Thanks for the save" Yugi said, "whoever he is, he was about to finish me off."

Luffy coughed.

"You don't feel so good" said Yugi "but what happened to you must be affecting us all. Wing Dragon of Ra! Let's get him back to the space station so Naruto and Sailor Moon can check up on him."

Yugi flew off on his dragon with Luffy. Pikachu runs up to see them leave.

"Man, what are those guys?" Pikachu asked. He turned to Lucario. "Lucario, what happened? What are you doing at the Mushroom Kingdom? When I last contacted you…"

Lucario was still in the rage state. "Back off!"

"Whoa. What's the matter?" asked Pikachu.

Lucario looks up and mistaken Pikachu for Mewtwo. Mewtwo had killed Lucario's trainer in the past.

"You! Mewtwo!"

"What? Mewtwo? Where?" Pikachu looked behind him to see if his arch nemesis is behind him. But he isn't.

"I'd finally found you, you murderer!"

"What are you're talking about?" Pikachu asked.

"This time you won't get away! FIGHT!" Lucario shouted.

Lucario send an Aura Sphere but Pikachu dodges. "Calm down, Lucario! It's me, Pikachu!" But Lucario wasted no time on words. He was about to do palm burst when Pikachu whacks him with his tail. Lucario trips Pikachu over with his tail. Pikachu leapt back up and head butted Lucario in the chest. Lucario crashed to a pillar but realized to give up. Pikachu leaps over Lucario and thunder shocked him on his butt.

Lucario yelped as he felt the sting on his rear but snarled at Pikachu, Pikachu used Skull Bash to defeat an enraged Lucario. After the battle, Lucario slowly sat up when Mario appeared.

"Pikachu, Lucario, stop this nonsense! Explain yourself" Mario said.

"I don't know what happened. He just attacked me" he addressed to Lucario.

"I… I saw you as the enemy" Lucario said after being snapped back to senses "I thought you were… a threat… I couldn't explain it. I'm terribly sorry, Pikachu."

"It's OK" Pikachu said "You seemed to be snapped out of it."

"He must have been influence by the same force that affected Link" Mario said. At this, Link walked past him.

"Link! What happened to you?" asked Lucario.

"I was captured by the invaders. Fortunately, Mario rescued me" Link said.

"He was held aboard that vessel" Mario said pointing to the sky which shown a star.

"I've came to find you, Mario" Lucario said "I was attacked by two warriors. They retreated to that space station."

"I do not know who where these invaders come or who leads them" Mario said "But it clear that Smash World faces a grave new challenge. Our world is merging with another. I can feel it."

"But we defeated Bowser!" Link said "we stopped him from merging Smash World with the Dark World."

"The Koopa King might still live" Mario said "and these new warriors might be his reinforcements."

"Then let's do something about it" Pikachu said "Lucario, let's head back to base. We can do a counterattack from there."

"I'll stay here and figure out what this power trying to engulf me is" Link said. "Good luck you two."

Back at the base, both Pikachu and Lucario begin talking on what happened.

"When I got to Hyrule, you aren't there" said Pikachu. "I did find someone who has grey hair though. I had him taken back to the infinitely. Then I followed your signal to Mario's castle. You got to stop running off like that, Lucario. We're a team. You can't take on these creeps alone."

"I know" Lucario grinned "I'll work on it."

"Go get yourself patched up" Pikachu grinned back. "In the meantime, I got the portal to jump us straight to that space station. We'll take them by surprise."

"Sounds like a plan, Pikachu" Lucario said "but I have to warn you, the portal has been a little off lately."

"Nothing I can't handle" Pikachu said as he typed on a keyboard noticing something strange "He's right. The portal was having a hard time focusing. Probably a side effect of the two universes merging. This matrix should be stable. Just a few type of keys and we should be back in business. There. That should do it."

"AAAARRRGGGHHHH!!! PPPIIKKKAAACCCHHHUUUU!!"

"What the…?!" Pikachu turned around and gasped.

Lucario was almost near death… by Broly, who held him in the air.

"HAHAHAHAHAHAHAHAHAHAHAHA!!!" Broly laughed. His eyes glowing yellow.

"Ggghh… Pikachu… help…" Lucario gasped.

"WHO ARE YOU?!" Pikachu snapped "LET LUCARIO GO!"

Broly turned to Pikachu. He had mistaken him for Goku.

"K…Kakarot…" Broly snarls as he tossed Lucario aside and walks up to Pikachu "Kakarooottt… KAKAROOOOOOOOTTTTTT!!!"

"You touched one hair on him…" Pikachu said, his eyes glowing yellow too "And you're dead."

"KAKAROT, YOU SHALL SUFFER THE WRATH OF THE LEGENDARY SUPER SAIYAN, BROLY!" Broly roared.

Broly charged at Pikachu with a KI Blast ready to blast him. But being a speedy little tyke he is, Pikachu dodges it and send a Thunder to send Broly flying. Pikachu then used Quick Attack after him and kicked him back to earth. Pikachu then used Thunder to shock Broly more and more before Broly is out cold.

After the battle, Pikachu rushed to Lucario's aid. "Lucario, are you alright?"

"I'm fine. Thank you, Pikachu. But who is that guy?"

"I don't how they broke through our defenses but they know this is our base. Seemed to call himself Broly. He's a Legendary Super Saiyan, if that what he calls himself, and he seemed to want to destroy a person named Kakarot."

"Look like you put a stop to that" Lucario smirked.

"Only one way to be sure. Let's take out that space station" Pikachu said as he and Lucario entered the portal.

They arrived at the space station. But Pikachu only came out the portal alone. Worried, he contacted Lucario. "Lucario. Where are you?"

"We apparently had been sent onto different location on the space station. I think the portal still needs some work." Lucario said.

"We need to regroup" Pikachu said "Stay where you are. I'll try to…" then he sensed something "Wait. Someone's coming."

He sees a guard walking with Luffy.

"We hold up a temperature holding personality as requested, Sailor Moon. It should hold Luffy until he's recovered" the guard said.

Pikachu decided to do a sneak attack on him.

"My thanks. If this merge thing continues, everyone's powers might be affected" Sailor Moon's voice said "I'll shall join you soon with an unexpected guest."

"Understood" the guard said before getting knocked out by Pikachu's Skull Bash. Pikachu then leaps up and smacked Luffy across the face.

Pikachu looked up to see Luffy's eyes glow again.

"Well now, this has just got a lot more interesting" Pikachu said as he got into his stance to fight Luffy. Luffy stretched out his arm for a Gum Gum Bazooka but Pikachu ducked under it. Pikachu then head butted Luffy. Luffy snarled as he used Gum Gum Storm. Pikachu used Quick Attack to dodge each other.

Soon, after a long battle, Pikachu defeats Luffy and was now contacting Lucario.

"Lucario, area secure. What is your situation?" asked Pikachu.

"I'm fine. We need to find locate the main command centre to cripple the station's capably" said Lucario.

"OK. Stay where you are. I'll get your signal and meet you up soon" Pikachu said.

"You're not going anyway!" came a voice. It was Sailor Moon. Pikachu used his Thunder Bolt but Sailor Moon knocks it away with her staff. Pikachu then sees the captured Sonic with her.

"Sonic?" Pikachu asked.

"I'd take it that you two know each other" Sailor Moon said to Sonic.

"He's Pikachu. An electric Pokémon and a formidable fighter which you would soon find out" Sonic said.

"Well, Pokémon" Sailor Moon said to Pikachu "I don't know what you're universe is doing to mine or what you are doing to this station" her eyes turned yellow. "but true warriors do not hid behind others. And if it's a fight you want, you soon be joining your friend in a cell."

"I don't think so. Give me your best attack!" Pikachu said.

Sailor Moon was about to use Moon Spiral Heart Attack but Pikachu stopped her with his ultimate attack, Volt Tackle. The attack instantly defeated Sailor Moon as she skidded alongside Luffy.

Pikachu contacted Lucario again.

"Lucario, you'll never guess who I bump into. Sonic the Hedgehog" Pikachu said.

"Sonic? What's he doing up here?" asked Lucario.

"Obviously I was a captive" Sonic said "but it would appear that we are now allies."

"Appearances can be deceiving" Pikachu said.

"True, but you'll be a fool if you don't need my help" Sonic said.

"What do you think, Lucario? Should we trust him this time?" Pikachu asked.

"Better do then better don't" Lucario said.

"OK then, Sonic." Pikachu used his Iron Tail to free Sonic of his handcuffs "Tell us what you know."

"Only that these warriors are unlike like I encountered" Sonic said "I do not know who commands them."

"Any ideas?" asked Pikachu.

"My only local thought is that Bowser is up to his no good tricks again" Sonic said "he's trying to finish the job on what he started earlier. With this new army" he looked down at the defeated Luffy and Sailor Moon "Now I need to find someone. Sorry, Pikachu, but we have to ask Mewtwo for help."

"Mewtwo? I don't like the sound of that. I still don't trust him" Pikachu said.

"Like or not, we need him" Sonic said "with the start of the invasion, he usually knows something about it."

"Before you do that" Pikachu said "You have to talk to Mario for help. He still don't trust you."

"I know. First, I'll reason with Mario. Then, I'll find Mewtwo" said Sonic. And he zoomed off.

To be continued…

Next time Yugi fans, Yugi will free the space station from Pikachu and Lucario. So stayed tuned.
