In Chicago there couldn't have been any trouble of confusions.

Well, if three bikes driving mice were counted as confusion a couple of years ago, that they beat their eternal arch enemy, Plutarkian Lawrence Limburger letting alone of his goons time after another, seemed become just stronger when mice scrapped poor Lawrence's tug transformer just few months ago, when Plutarkian fish tried to get a whole Earth to Plutark by that machine.

But now there was moving something on the nightly city's roofs, which nobody would want to even see.

That kind of nightmare, which only a lunatic would want to face.

One so disgusting and evil looking creature, whose long, about 5 meters tall clever black tail was flapping with the fall wind while its owner leaped from roof to another its drool pouring at the street.

"What the…" wondered on the dark, only by the streetlights' enlightened, street walking grey coat wearing man taking his hat from his head stopping, to look on his hat, which had drool on it.

"God damn juvenile delinquents just dare to spit on innocent citizens!" thought angry man while cleaning his hat when the creature started to get closer to him down the wall, even more quiet than mouse, smelling its prey's fear under that unconscious composition.

Its only life mission was only to kill or exploit other life forms which helped to breed more creatures like it.

Black, human-like creature touched a while its unsuspecting victim's right shoulder. Then the man started to wonder, who was behind him…

"Yes wha…" asked the man looking back.

And he froze in that place when the hissing, in the dark being creature grabbed from man's head and it did its job.

"NOO! NOOOOOOOOOOOO!" screamed poor man when the huge creature opened its mouth, penetrating its innocent victim by its tongue.

Let alone blood flown to the streetlight's iron and the horrifying, death leading scream.


"When these mice are riding on the road, Limburger's gonna be cold! When there's nothing to…" sang the Biker Mice when they suddenly heard horrifying scream from close stopping immediately.

"Ou mama! What was that?" wondered singing stopped Modo as his bros thoughts were returning.

"Maybe someone is in trouble…" concluded Vinnie Throttle adding: - Or even worse situation, bros…

"Well guys, if there hasn't been made anything more than Limburger's goons butt kicking and eating hot dogs, how about we checked that out?" suggested white furry Martian whole trio starting to shout.

"It's time to ROCK AND RIDE!"

After moment when mice arrived in the place the answer was straight before their eyes: grey coat wearing brown hair man's head was bleeding to a sewer next to the street.

"Who... could have even done something like that?" wondered Throttle looking man's bleeding forehead: it looked like that something had gone through it.

Drilling machine; maybe, but even the best machines couldn't get so bad damage like that, because a hole gone through the man's forehead was almost perfectly straight.

"Well if someone has done that, you have to be really heartless." said Modo stepping with Throttle to check out, who really was that man.

"Hmmm… It's Carl Tax, one of those foremans from that building and electric company. " told Modo giving the passport to Throttle to see himself how bad damage man's murderer had caused.

"That's right, bro! This is already a fourth Electrobuildmax incident in row of the three weeks. First a secretary supposedly jumps from the window a head in condition just like this. Then after a while a general manager falls from the roof although without this headmark, skull broken and then…" counted Throttle aloud two of the recent murders when Vinnie added the third one: "That third, one of Charley's former school friends, that company's chairman was scorched in fire just last weekend!"

"And what these incidents have in common? Surely that gill fish Limburger is behind this!" guessed Modo while unpleasant situation started to sink into his antennas.

"Maybe you're right, bro, but even Limburger hasn't acquired someone who could do something this raw and sharp to his worker." thought Throttle walking in a circle for a moment his head filling with questions. "Correct. Not maybe so far but I'm not going to guess anything yet though this doesn't look any good."

"But when something strange happens, you can bet even your tail that Limburger is behind things like this! Do you think, that there is something perfectly emotionless creature out there?" asked Vinnie looking to black and dark apartment building's roof feeling, that they were watched over by something unnatural.

But he couldn't even know how sly this darkness using creature was. It was watching them darkness disguising it while its drool was pouring down the wall to the street.

"Like my grey furry mamma used to say: "Only your own fear can be lethal, not even the ugliest bogeyman!" " blurted Modo out when Throttle took his glasses off for a little moment looking quickly at the apartment building while his bros wielded poor dead man with them wind pressing.

"This guy's family is going to have rough as well because of this." mourned grey furry mouse while lightning struck in the sky making his glasses wiping Throttle to startle.

After that petty second he almost shocked when he believed that he just had seen the murderer.

Black leathery creature remarkably bigger than human, which had no eyes.

"What now, Throttle? Was it that lightning what…" asked Vinnie while Throttle put his glasses back, trying to deny what he possibly had just seen.

"Let's take this man to the police and fast! I've really got a feeling that there's moving something on those roofs!" told Throttle putting the man into his sidecar with Modo's help.

"Sa… ve… me…" spilled the man getting mice to startle: how could that human still be alive?

"Don't speak, sir! It doesn't do you any good." recommended Modo putting the bleeding man into the sidecar when Throttle started to have a little conversation despite the recommendation.

"Tell, sir, who attacked you." asked Throttle while man got a heart attack: it was still there and it was only waiting that its prey was left alone.

"It... IT'S HERE!" screamed panicking man pointing to the dark building's roof, but there was nothing on it when mice looked in there.

"What 'it'? You don't mean human, Mr. Tax?"

"It's not hu… man… it's… it's…" blurted Carl while his breathing got word by word heavier.

"What then? Just say it!" exclaimed amber furry (amber = gold brown) when the man said just before his giving up to the ghost: - Xe… no…

"Some Xenno right? Oh man, is here some other gatecrasher than Limburger and us?" complained Vinnie enlightened only by the streetlights, when the drool poured on him.

"Oh man! This is even worse than that Plutarkian lawyer!" whined white furry Martian turning his back to the side, not suspecting what was coming closer to him.

"Don't kill those rats, my dear pet! Bring them to me, so I can finish them off personally." recalled diabolically grinning creature while crawling closer to Vinnie.

"Take out the smallest first, so the chaos may rise." thought the snakelike creature teasing Vinnie by pouring its drool to the Martian's antennas.

"What pipe is leaking up ther…" said the Martian when the black creature grabbed him in that second without any warning, lifting him up to the wall despite the resistance!

"Come on, Vinnie! Let's just get…" blurted Throttle turning back like Modo noticing that Vinnie was gone and he had left only his helmet on the street surrounded by drool.

"Vinnie? Vincent?" shouted mice hearing their bro's complaining from the roof jumping on their bikes to get Vinnie and his kidnapper stop.

But this creature just knew what it had to do, just like its sisters.

And there was no way to shoot it when it put Vinnie with its long tail to its chasers' line of fire!

"Ou mama! What on Earth is that thing?" shouted Modo when the creature leaped easily to the next roof resisting Vinnie in its tail's squeeze when the poor Martian hit his right cheek on the roof when creature just tightened the tail.

"OH MAAN! That's it, whatever masquerade clown you are!" snarled white furry Martian trying to get his hands off that tight squeeze while his face was hitting the roof and not quite prettily.

There would be a one long chase, unless Vinnie could get out of that creature's tail's squeeze and there was no way to shoot it, because Vinnie was just in his bros' line of fire.

"Time to raise some stakes!" thought the creature rushing through the water tank's boards while Vinnie got a piece of board right to his mouth.

That's what made him angry!

"Modo, look out!" shouted Throttle to his bro, who was driving straight to the water tank's water. And in no time grey furry Martian fell on his back letting alone of his bike. Throttle tried to continue the chase and tried to figure out, how that creature could be stopped.

Luckily Vinnie managed to get out one of his ignition sticks from his weapon belt, which fell from Martian's hand to back to Throttle's hands.

"I hope that this will take that creep down!" thought Throttle throwing flaming stick straight to the creature's big, bent, sex organ looking head, which only the amber furry mouse could see with his glasses from the dark night.

When the stick hit the creature's head, it screamed icily and it let Vinnie go of the squeeze when the Martian hit the roof once again. Throttle was shocked of that scream; it was something so unique and scary that it almost froze him.

He needed to take down that creature, but it was almost impossible when the creature's yellow acid started to leak from its head. It corroded every possible building on which that creature had jumped.

"Oh no! This creep's blood really isn't any kind of normal acid; this is way much worse stuff!"

He was right. It wasn't normal to see buildings corroded down and it could be risky to chase that creature even further, leaving amber furry Martian only one choice…

"Damn it! It's corroding everything under it! I just hate to do this, but I've got no choice!" thought Throttle braking on one apartment building's roof, shooting a tracker to fast creature's back when it lost to the dark to take care of its wounds…

"Hey bros! If you don't remember here's one wounded mouse!" complained Vinnie Throttle turning his bike to drive to his hurt injured bro.

"Easily Vincent! Just let your bike take you to the carage, so Modo and I will get that metal cover to cover it." told Throttle lifting his bro up while his red bike and Modo arrived there.

"Drive to the carage and pronto, Vinnie! Modo, you come with me to get that cover." said amber furry Martian putting Vinnie to his bike with Modo's help. After that the bike drove to garage with the sidecar and its poor shape being owner like there was fire under the tail.

But now there was going on even worse incident than that: now there were many lives on the line and soon there would become a pile of them!

"Well, Throttle. Why do we hurry like this? Is it about that masquerade clown?" questioned head-shaking Modo while Throttle recalled, what their mentor and educator Stoker had told from that creature.

"Seriously, big bro: it's not a masquerade clown! It's one of those diabolical tool head creeps, whose blood is deadly acid." answered Throttle trying to keep his head calm, although terrible horror events were spinning in his thoughts.

"One of them? They were supposed to be only lunatics' tableaus from their pervert fantasies!"

"Stoker just knew much better than us: those Xenomorphs really exist!" continued Throttle when Modo opened his mouth like struck by the lightning.

"Ou mama! We should have been more accurate with that. What's that leather freak going to do next?" wondered grey furry mouse driving with his bro to a baseball station. And when they got there, the duo flew into their giant scoreboard accommodation through the place of number 4.

"I don't even want to think, what that slime ball is doing here in Chicago!" said Throttle putting a trailer after the duo's bikes while Modo was searching metal cover made from Martian armor under the sheets.

"So – UNNGGHH! – let's hurry up, bro! It's already dark in the whole city." suggested Modo lifting the cover with Throttle on the trailer, and after that they drove as fast as they could to Charley's carage.

"Hmm. This is strange..." blurted Throttle suddenly making Modo to wonder.

"When I chased that death acid leaking leather freak over those roofs, I decided to give up the chase and to invoke to the tracker."

"What is it then? Is that tracker broken or what?"

"I'm not getting any signal from it! That devil must have already noticed that tracker I shot on its back." And in that the amber furry mouse was just right…


"Smart…" thought in the dark alley being creature while watching the mouse head like tracker, which it had just taken from its back.

"But not smart enough!" And in that second tracker was broken into many countless pieces, when the creature smashed it with its big tail.

Now that creature didn't have anything more to do than to return to its lord.

Just to tell about failure after all that adaptation to the city's environment.

But now it knew, after a couple of months training, who were its opponents. Finally it knew, how strong and fast they were.

And yet better, it knew the weakness of those rodents...

Group work and taking care of each other, which would only end up badly!

"The days of those mice are numbered." thought the snakelike creature crawling into the sewer, and after that it ran so fast that sewer rats almost fell on their backs when the creature ran with deadly speed along the wall to its home place.

But more than that it hoped that its wound would heal up and as fast as possible, or its lord would start to complain from that floor-corroding acid.


"Ohh! I guess that our snake friend has returned from its mission." guessed purple colour clothes wearing Plutarkian hearing from a before his eyes being sewer hole snakelike shrieking.

"Yes it is her, your incomparable moldiness! Lester has come to home!" mentioned Plutarkian's mad scientist professor Karbunkle making sure from surveillance cameras video, that the creature in the sewer was his boss's own.

Itself Lawrence Limburger's, that cocky Plutarkian's. He had lost his nerves because of Biker Mice always made jokes on him, but now he was happy to his 'pet's' work, although its killing way seemed even in his eyes maybe a little too brutal.

But when he had given it a chance to adapt to the environment several weeks and let it do, what it did best, it seemed like that his new 'pet' was worth all of that pain, when it had been captured. And after that capture, he couldn't have felt any better because he knew it already because of the metal collar, which was on the creature's left shoulder.

"Well then, my dear giant snake, you can friendly go to your cage to have some rest." said the Plutarkian looking his standing, about 2.3 meters tall 'pet', whose legs looked so thin but still so strong that it could kick men really far away.

"Hey, Lester! Could you give me some quality treatment?" asked in the glass cage being a crazy little masochistic mutant called Fredrik making Lester to hiss affirmatively for that. After that the Xenomorph got on its back and started kick the mutant to the glass, which could take every possible hit.

"OH HOH HOH HOH! This rocks!" yelled Fred while the Xenomorph kicked it into the glass trying to relax from voices and trying to remember smell.

And particularly to that smell which came from those motorcycles.

Lester pitied, because departed from its sisters it had to live under that Plutarkian fish's orders and do whatever he said to it.

Just that it could make it back to its queen, which really wasn't any kind of gentle mother…

And without that mini transmitter, which was under that creature's jaw and what made that snake to do whatever Limburger wanted it to do, it would still be free without worrying any kind of orders or other worries, like that it would be shot to dead.

With that tracker professor Karbunkle had realized one day one amazing thing: with the radio and that transmitter he could even translate that primal rage owning monster's tongue's moves and hissing as some kind of speech.

Though snakelike creature's understanding info about civilization was really primitive (= not much info about something), speeches were simply broken chatter of words, which Lester couldn't make into sentences.

And it didn't even understand why humans or any other life forms feel some moods or feelings.

From those moods it had experienced the most was the fear of those soldiers and civilians which that alien had killed, but that's why it was still alive.

It had deserved its life and some day that Plutarkian would pay for that creature's capture from its nest some time ago!

"Taste of blood is a taste of victory, my dear Lester. Try to remember that when you'll take out those Biker Mice out with that equipment of yours!" teased Limburger making Lester to hit its tail against the glass frightening the Plutarkian making him fall on his face.

"Gees, boss! Didn't I mention already back then when we acquired that tool leather freak to us, that it's dangerous and…" mentioned Limburger's number one man, grease pouring Greasepit to his boss, who just answered back to him sarcastically: "And what more, you foolish grease tank?"

"That it leaves its drool there wherever it moves! I'm already going to have some fears to come to here when here's dwelling a creature like that!" said Greasepit pointing to the Fred kicking monster, which just held its hands calmly behind its back.

"And with the creature just like that those damn bunny gearwheel hamsters are going to be beaten up, so remember this, Greasepit…"

"Yeah, boss?"

"DON'T EVER DISPUTE MY DECISIONSSSSS!" shouted Plutarkian straight to Greasepit's face making him faint on the lab's floor which was now full of grease and drool.

"Or actually, that our snake's drool is starting to be seen all over in my building. Luckily it has that transmitter on its jaw or otherwise my secretary letting alone the thugs would already be in pieces!" blurted Plutarkian out while taking the drool out of his shoes. That was a good example from that why Lester was good to be held in leash.

"So Mr. Limburger, why did we acquire that snake in the first place? I mean that tail freak does its job good, but…"

"You repulsive motor workshop's distortion will never understand, what all do I see in that what you petrol canister consider as weird! But as long as you asked, I just could start repeat my plan from the very beginning." answered Plutarkian while taking from lab's shelf his own worm dish from where he started to eat his from earth taken worms. That sound annoyed Lester, because it had itself liked from them.

Along killing and causing chaos.

"As you can see from recent weeks, my plan 'Electrobuildmax' has worked so far perfectly, big thanks for this drool pouring devil's work. That company takes care of Chicago's main electric and building projects, including the electricity in the city sewers."

"So what are you going to do with that electricity, boss? To fry this whole city?" asked Greasepit while his boss ate his worms.

"No no no no! Of course not, my dear grease tank! It's just one necessary step in this operation. Thugs have been setting many weeks those transmitters after every 10 meters in sewers just under our feet, so I could…" In the best part Limburger was suffocating making Greasepit to help his boss. Unfortunately he didn't remember, what was that famous maneuver which was used in the situations like this.

"Hemretch maneuver? No no no! Ovaretsk maneuver? No no no!" thought Greasepit over when his boss threw up the worms on the floor making in the cage being xenomorph to laugh a bit to its enslaver's pain.

"Oh that's it! It was that Heimli…" blurted Greasepit when his boss hit him to his head, continuing after that his speech.

"With the help of this xenomorph when the final principal (= 'big human') let's say 'gives up to the ghost by a mysterious reason', nobody wants to work in there and it's mine! MINE to use! HAH HAH HAH HAH HAH HAA!"

"But boss! If those principals from that company just said 'no' to you when you offered them a lot of cash, why do we need that company?" asked from hitting resuscitating (= to come back to senses) Greasepit making Limburger to sigh for that man's idiotic personality.

"Phase 1: Eliminate the principals of Electrobuildmax. Phase 2: Buy the company with ridiculously low price. Phase 3: Cause with transmitters short circuits to whole Chicago and turn off the electricity for a while. Phase 4: Put this deadly acid on the waterworks tanks and let the acid to go all the way shown by those transmitters to there, where are the main generators of city financed by Electrobuildmax. And phase 5: when the electricity comes back on, whole Chicago will be all ablaze every along every cement pieces and I'll just watch the burn of this city with our devil! And after that, when Chicago would be in ruins, I would just send it to my dear home planet Plutark…" Limburger sighed heavily with the ending word looking at the same time in a little tube being yellow acid, which really shouldn't be thrown everywhere you'd like throw it.

"But then… then there are those three damn mice, which just can't keep their noses off from my plans! Luckily I have this triumph and quoting my former lord Stilton: 'So fascinating life form just because of its emotionless and lack of moral!', although this tall and sharp-tail friend of ours isn't in that natural way fascinating." continued Limburger watching its rest having monster, which snored letting its tongue out occasionally.

"But still, boss! What if Lester runs away and those rats will find it? Then all hell breaks loose if they find out, who… I mean what is behind those company incidents."

"Don't you worry about it, Greasepit! Just let me to make out plans and Lester to do its job. That's what that distortion of devil does best."

"I still don't trust it even a bit, Mr. Limburger! Every time when it's out of its cage, it starts to tease me and goons by its drool. I say that let's just fry that monster before it makes from us sausage!"

"What is it, Greasepit? Don't you like, that your partner does its job better than you and gets its reward in the end?"

"That's not, what I'm meaning, boss…" started grease pouring man turning around for a second; "I mean that it will be busted, and I can't help with that feeling when there are mice in this town."

"Just get back to your work, you idiot! The days of those motorcycle rats will be numbered, and so are yours as well, so stop soon talking RUBBISH! DID I MADE MYSELF CLEAR ENOUGH?" shouted Plutarkian making Greasepit to step away his grease spilling all over the floors.

"Before everything was so easy and so enjoyable. I sold lands, slaves etc., but there's nothing, really nothing is comparable with this killing machine!" And when Plutarkian watched over the cage, he noticed that Lester's head wound was healing.

"Oh yes, your baronic cheesiness! You really must search better killer than Lester, though there would be available that Predator as well!"

"I just hate dreadlocks like that, my professor! And besides, although they've got brains and good technology, there's no way to get to the same level with Lester." praised the Stinkfish out aloud walking out from the lab leaving his 'pet' and professor there including Fred the mutant.

But if that stinking Plutarkian wouldn't keep his promise.

She would make him pay for that capture from her nest and heavily.

That nest, which was on the Mars planet's glacier's covered zone, where almost nothing grew.

Except that one little, orange, fragile flower, from what she took care of as best as she could.
