"I can't believe it. A ride on the Startrain! Shooting across the sea from Paris to the UK. This is incredible!" Miles said.
"It'll be quite a fun experience." Tsuki said.
"You sure seem excited about this, Miles." Omnimon said.
"I'm a mechanical geek. I get excited by vehicles and giant robots." Miles said. "Plus they inspire new Animechs for development."
"I can imagine." Kazuichi said. " Maybe one day you could build a train Animech. And fashion it after a snake."
"But what if a villain strikes while we're gone?" Kendo asked.
"That's not for any of you to worry about." Marinette said. "Besides, I'm prepared." she said, taking out a small box. "This one has the Horse Miraculous inside. So if something does happen, I can get someone onto our side."
"Right. Cause it has the power of Teleportation." Levy said.
"Well, let's not worry about that now. We've got a train to catch… and ride!" Kazuichi said.
"A train hmm? At least it isn't a demon possessed one." Miriam said.
"It's...just a train." Miles said as they got onboard.
At the Agreste mansion…
"Hey Gabe." Dabi piped up. "What happened to that Akuma you sent out earlier?"
"I lost track of it. I was hoping to enlist Rogercop again, but his negative thoughts dwindled. After that, I lost its presence." Gabriel said.
"That can't be good." Techno said. "If that akuma possesses someone and we don't know who it is… we'll need to keep an eye on the news, they're bound to make a scene."
"I'll keep the news channel on." Boba said. "Gabriel, see if you can find the butterfly. Akumas are drawn to negativity, so whoever it's being drawn towards, they're going to do something big."
"Unfortunately, even my power has limits." Gabriel said. "I can only sense my Akumas presence for so long. If it's too far away, I can't track it."
"Hmm...so it's likely already off somewhere. Like a bus or a plane or…" DaDan said.
"A train?" Boba said.
"Yeah, a train." DaDan agreed.
"No, a train! The akuma's taken over the Startrain!" Boba pointed out, showing footage of the train in space.
"No wonder I couldn't sense it." Gabriel said. "Well, no harm done."
"Uh...sir...hate to tell you this but...your son and his class was on that train." Pete said.
"My god…" Gabriel said. "Boba, get to your ship. I need you up there to rescue my son."
"Damn it… be thankful I'm not charging you for this." Boba said as he ran to get to the Slave I.
Back on the Startrain…
"Uh… is it me, or have we achieved liftoff?" Scarlet asked.
"Uh...guys?" Miles said pointing to the window. "I don't think we're on Earth anymore."
"The heck? I know it's a startrain, but this is ridiculous." Kazuichi said.
"An Akuma must've snuck aboard and possessed Max's mom." Kendo said.
"Wow...that is incredibly specific. We gotta convince her to take us back to Earth." Miles said.
"I'll speak to her." Max said floating over to the PA System. "Mom!"
"Max, do you see this? I'm Startrain!" his mom replied.
"You need to stop this. Please go back." Max said.
"I'm not going back. We'll ride through the stars forever!" Startrain said as the car started to heat up.
"So warm...she must be messing with the temperature system." Miles said.
"We need to get to the front." Ladybug said after having transformed.
"But...what about Max? With the temps constantly changing, he's not gonna last long." Kazuichi said.
"Well...not on his own anyway." Ladybug said. "Max Kanté, here's the Miraculous of the Horse, which grants the power of Teleportation. You will use it for the greater good. Once the job is done, you will return the Miraculous to me. Can I trust you?"
"You can count on me 100%! I'll do anything to save these people...and my mom." Max said Ladybug then handed him a pair of glasses as flying out of them was a small horse like Kwami.
"And to whom do I have the pleasure of speaking to?" it asked.
"Hi, my name's Max." Max introduced.
"Are you Glorious and Famous?" she asked.
"Kaalki, this isn't the time for that. He's perfect. We're going to the last car, that's where Startrain is." Ladybug said.
"All you need to say is 'Kaalki, full gallop'." Kaalki said as Max switched his glasses with the Miraculous.
"Kaalki, full gallop!" Max said as Kaalki flew into the glasses, turning the glass in them black as his hair was styled back and tied in a ponytail as a brown outfit appeared on him with some horseshoe marks on it as he then posed.
"Okay, let's do this." Miles said before a hole was blasted in the side of the car behind them as entering was Boba.
"Well...look at this." Boba said. "Looks like I get to make Hawk Moth even more happy."
"Boba Fett?!" Scarlet said. "What the heck are you doing here?"
"I was going to take this train back to Earth and get the akuma into Hawk Moth's range… but, I've got a better idea." the bounty hunter said as he drew his blaster.
"Is this really the time for this?" Omnimon asked.
"Don't worry. I can get him out." Max said as they went into the next car as he tossed the horseshoe boomerang as it hit a button, locking Boba Fett in before ejecting him deep into space. "When you find some aliens, tell them you sent out courtesy of Pegasus!"
"God damn!" Boba cursed as he activated his jetpack. "Grr.. okay, that's it. I'm going to…" he said before his pack exploded. "Damn heat overheated it." he growled.
"Nice work, Pegasus. Now, let's get Startrain." Kazuichi said.
"Wait, we're just gonna leave Boba floating out there?" Cat Noir asked.
"His armor will protect him until he can get back to his ship." Scarlet explained. "Besides, do we really wanna go outside to get him?"
"Yeah...let's go." Omnimon said as they hurried to the front of the train as they fought off any fighter bots before reaching it.
"Cataclysm!" Cat Noir said, destroying the deadman switch.
"Okay. My turn. Voyage!" Pegasus said creating a hole in space as they flew through it, going into London...right through Big Ben itself. "Sorry, looks like I got the spatial coordinates wrong."
"Well, we were going to London." Miles said.
"I got this. Miraculous Ladybug!" Ladybug said as the train was transported back onto the tracks of a nearby station in London.
"Well...that was quite the ride. But...I think I'm not going to be riding anymore trains for a while." Miles said.
"Amen to that." Scarlet said. "I wonder if Boba got back to his ship okay?"
"He'll be fine. He definitely won't burn up on re-entry." Miles said.
Elsewhere….
"Ugh...didn't think this thing would ever get back. Okay. Least I'm back in…" he said before seeing a large bridge. "San Francisco?! Great, missed my mark by a few thousand miles. *sigh* This villain team thing has really done murder on my methods. Better call for a pick-up...except I can't cause my comm was back on my ship." he groaned. "Guess I better get a plane back."
