A/N: the characters from Sonic are from the IDW [2018], take place in Lupin III Part V.
In unknown city, everything was normal.
However there was certain phantom thief called Lupin The IIIRD, however Lupin was encounter something alternate universe.
In Sonic World/Mobius.
Big the Cat and Froggy asleep under a tree, fishing by a lake. He is suddenly roused by the sound of an alarm coming from Dr. Eggman's base, which is not too far away.
Eggman's base - Outside.
The tower's floodlights switch on, and several E-30 Laser Tanks make moves to protect the base from Sonic the Hedgehog, who is dashing their way. The treaded robots move outside the gates, which promptly close. As soon as Sonic comes into range, the Laser Tanks open fire. As Sonic nimbly outruns the lasers, several turrets fire a hail of rockets at him. The rockets explode on the ground behind Sonic, who uses the Laser Tanks as leverage to leap inside the perimeter of Eggman's base, evading their laser fire as he runs. Several E-12 Behemoth robots activate themselves and, leaping up, cut Sonic off, forcing him to break left. One Behemoth begins to chase Sonic.
The Behemoth chases Sonic down a tunnel. There is another Behemoth further down the tunnel, but Sonic runs to the left, causing the two Behemoths to run into each other and explode. On his way out, he accidentally steps on a spring pad, which bounces him into the air. His body is met with the fist of a Behemoth which sends him flying. Miles "Tails" Prower and Amy Rose, who are both seated in the Tornado, witnesses this.
Tails: Sonic!
The Tornado swoops down, but takes a few hits by the turrets. Amy cringes at the hits, but then is horrified to see that the Tornado is on fire.
Amy to Tails: Smoke! Do something, Tails!
Amy to Tails: Tails, the plane's on fire! What are we gonna do?!
Tails to Amy: Don't worry, Amy!
Tails pulls a lever next to him.
Tails: This first!
The Tornado launches a rocket. It speeds toward the falling Sonic, and its tip breaks off, revealing a Power Ring. It falls in the same area that Sonic is falling. A moment later, there is a bright flash, and Sonic barrels back toward the base. He spins right into the Laser Tanks, destroying them on the spot. He slices through two Behemoths like butter. A third Behemoth tries to pin the hedgehog down, but is uppercut when Sonic flies up from underneath it. He breaks through one of the tower's lights and enters the base. Meanwhile, Tails prepares for a crash landing.
Tails to Amy: Hang on, Amy!
The Tornado bounces a few times. Amy's eyes widen in horror, as there is a massive rock in their path.
Amy to Tails: We're gonna crash!
Tails to Amy: I know!
Suddenly a spiked fist punches through the rock, shattering it completely. The plane safely skids to a stop. Tails looks up to see who saved them.
Tails: [gasps] Knuckles!
Knuckles: Hmph.
Amy to Tails: What's the matter with him?
Knuckles the Echidna's gaze is fixed on Eggman's base. Smoke rises from the robots that Sonic had destroyed.
Knuckles: Overkill, just like always.
Eggman's base - inside. The base is undergoing lock down. All of the interior doors are closing.
Eggman's base - Eggman's control room. Dr. Eggman's along with Orbot and Cubot are looking at a radar. Orbot then turns toward his master.
Orbot to Eggman: Dr. Eggman, the facility is on 100% lock down.
Eggman to Orbot: Darn! Why does that Sonic always get in my way...
Cream the Rabbit, who is trapped inside a glass sphere with her Chao friend Cheese, answers.
Cream to Eggman: He doesn't get in your way, Dr. Eggman. Sonic just tries to stop you from doing all the bad things you like to do.
Cheese: Chao chao...
Eggman to Cream: Oh, is that so?
Eggman holds up a red Chaos Emerald.
Eggman to Cream: When I put this last Chaos Emerald into this machine, my machine will have limitless power!
Cream to Eggman: But you can't do that!
Cheese: Chao chao chao!
Rouge the Bat is perched on an overhead ledge, taking in the scene.
Cream to Eggman: That's right! Sonic won't let you get away with this!
Eggman to Cream: All the walls have been closed! It wouldn't be easy even for Sonic to... break it down.
Sonic breaks through the wall, startling Eggman.
Cream: !
Cheese: Chao!
Eggman: Oh no!
His look of surprise changes to an evil grin.
Eggman to Sonic: However... Your Too late.
Eggman places the Chaos Emerald into a slot in the machine, closes the hatch, and presses various buttons. He then holds up an activation button.
Eggman to Sonic: You'll never stop me now, Sonic. Hahaha! All I have to do is to push this little button. Hahahaha!
Sonic to Eggman: So. All I have to do is to take it away from you first.
Eggman cringes, then smiles in delight as an E-13 Guardbot appears behind Sonic.
Eggman to Sonic: Why don't you give it a try then.
The Guardbot fires at Sonic, who escapes its lasers with ease.
Sonic: Catch me!
Eggman: Don't let him get away!
Rouge cringes as stray lasers hit near her hiding spot.
Eggman: Stop him no matter what!
But Sonic lands right in front of Eggman just as Guardbot is turning towards them.
Eggman: 🖐 Whaaa! No! Hold your fire!
Sonic leaps out of the way just as Guardbot begins firing, forcing Eggman to duck. When the torrent of firepower ends, he stands up and reaches for the switch.
Eggman: Ha! Here we go!
Eggman presses the button, but is surprised to see that the machine is crackling and riddled with laser holes.
Eggman: Whaa? What have you done?!
Orbot: oh no...
Cubot: so..is this the end..?
Orbot to Cubot: don't break the fourth wall..
Everyone looks on as a strange energy build inside the machine. Then suddenly, a massive field of light spawns from the machine and pulsates outward, enveloping everything and everyone in its brightness. It escapes the base and keeps growing outward. Even Tails, Amy, and Knuckles notice it.
Amy: What... is that?
Knuckles: Chaos Control.
The light continues to move outward, enveloping the three onlookers and even Big the Cat.
An unknown location.
Sonic was laying on the road unconscious, when Fiat 500 F stop in front of Sonic.
two men came out from the Fiat 500 F, to take a look at Sonic the Hedgehog.
?#1: well this is something, you never see everyday..
?#2: are you sure that someone's wearing a costume got drunk and passed out..?
the man in the blue jacket touched Sonic, however it wasn't a costume.
?#1 to ?#2: there's no way that this thing can't be a costume.
?#2 to ?#1: so I guess this thing is some type of mutation sentient animal...?
?#1 to ?#2: you're right about that, this thing is definitely organic.
the man in the Blue Jackets put the Sonic in the back of the seat of the Fiat 500 F.
?#2 to ?#1: are you really sure about this..?
?#1 to ?#2: come on now, I can't leave this poor helpless animal in the road.
they drove off in their Fiat 500 F with Sonic in the backseat still unconscious.
