E. Gadd was in his lab, fixing something up. "I wonder how Nitori is doing?" He wondered. "Why don't you video chat with her? I bet she's probably thinking the same thing." FLUDD suggested. "Brilliant idea!" E. Gadd exclaimed as he walked to his computer.
Suddenly, little dark orbs came up from the floor as FLUDD noticed this. "What is this?" He wondered as the orbs formed into something as it walked up to E. Gadd.
"Hmm?" E. Gadd wondered as he turned around. "Oh my!" He exclaimed.
Meanwhile...
Marisa and Reimu jumped out of the Warp Pipe and walked to Peach's castle. "I can't believe how they fixed it up so fast." Marisa said. "Those Lumas sure are something." Reimu said as Marisa nodded in agreement. They then noticed a certain airplane parked in front of the castle. "Oh, I guess Sonic is visiting." Reimu said.
"Are you telling me you had this crazy adventure and you didn't invite me?!" Sonic exclaimed. "Yukari was possessed by Shadow Queen, of course it'd be crazy." Luigi said. "And YOU..." Sonic said, pointing at Mario. "How the HELL did you die so easily?!" "It was Yukari and her crazy spell cards, I didn't think she was so powerful." Mario muttered.
Marisa and Reimu walked in and Sonic looked at them. "What are you freaking out about? I heard you complaining before we got to the door." Marisa said. "Oh he's just mad that we took on the Shadow Queen without him." Daisy said. "Ah."
"Honestly, you could've called me up after Mario was killed, that way I would've kicked Shadow Queen's butt." Sonic muttered.
"Hey, where's Rosalina?" Reimu asked as she sat down next to Peach. "She decided to take a walk." Peach said as Toadsworth gave both of them tea. "Would you like some tea, Master Sonic?" He asked. "Yeah, sure." Sonic said.
Rosalina walked around Toad Town and took a deep breath. "It just feels good not being hunted down by Ansem anymore." She said with a smile. "It sure is." Polari said as he was next to Rosalina.
"What the heck is THAT?!" A Toad asked as Rosalina and Polari turned around to see a strange being walking up to her, with a green sword! "Is that a Heartless?" Polari asked. "I dunno..." Rosalina said.
The being ran up to Rosalina and slashed her, but she quickly dodged it as she kicked the being, but the being blocked it with the sword and then kicked her down.
Rosalina sweep kicked the being as it fell to the ground, as Rosalina jumped up and kicked the being in the chest. She then grabbed the sword and raised it up in the air and then stabbed the being.
The being instantly disappeared along with the sword that Rosalina had. "What the heck was that all about?" Polari wondered. "I dunno, but it messed with the wrong girl." She said as she continued walking. "Why do I have this feeling something bad is going to happen?" Polari wondered.
"Look, all I'm saying is, if that Crystal Star was in Mobius, I would've helped defeat Shadow Queen with you guys, but no, it just had to be where Mega Man lives." Sonic muttered. "Would you calm down?" Marisa asked. "The Crystal Stars went off somewhere else after they revived everyone who was killed by either Ansem or Yukari. So we may never know where the hell they are now." She said.
The doors slammed open as Riku ran in. "We have a situation." He said. "Bowser again?" Peach asked. "Well no..." He said as he pointed outside as they all looked outside.
Strange beings were attacking the Mushroom Kingdom as Rosalina, Sora, Kairi, Roxas, Xion and Namine were attacking the beings. "We decided to come visit you guys when those things decided to show up." He said. "Heartless?" Reimu asked. "No...worse." Sonic said as he immediately ran out and spin dashed into one of them.
A being aimed at Rosalina and shot her, but Xion jumped in and used Reflega. "Thanks." Rosalina said.
"What are these guys doing here?" Sonic asked as he backed into Sora. "You know these guys?" Sora asked as he used Firaga on one of them who was going to punch a defenseless Toad. "Primids, we faced them a long time ago." He explained as he kicked one away who was running at them.
"So they're not Heartless?" Reimu asked as she fired danmaku at one of them. "Nope." Mario said as he grabbed one of the Primids and threw them to a giant Primid. "Makes me wonder what the hell they're doing here, we destroyed Tabuu a long time ago." Sonic said.
"Do you think maybe this Tabuu dude is back?" Marisa asked as she used Master Spark on a Metal Primid. "I doubt it, although it would make sense if Ansem's distortion thing would make him still be alive." Peach said as she kicked one down, followed by Daisy jumping up and elbowing the Primid.
"Distortion or not, I'm wondering how the hell these things are alive and well." Sonic said as he spin dashed into a couple of Primids.
Roxas and Namine both used Zantetsuken on some Sword Primids and both high fived. "TAKE THIS!" Xion yelled as she used Thundaga at them.
Rosalina and Riku were back-to-back as the Primids were surrounding them. "What do you think?" Riku asked. "I think we're going to have an interesting challenge." Rosalina said. "That's what I was thinking." He said.
Suddenly, water washed away the Primids that was surrounding them as the two noticed Nitori up in the air. "Good thing you have a moat or else that wouldn't work!" She exclaimed as Peach gave her a thumbs up.
"Hey guys?" Kairi said as she pointed to a portal that just opened up. "What the heck?" Sonic wondered as an old man walked out with a Keyblade. "Xehanort." Riku said.
So here's the next Mega Crossover. (You might want to thank Ziden for this idea.)
But seriously, after trying to figure out a good name for this new crossover story, the title was the best I could come up with. Oh well.
