I do not own Transformers.

Shockwave was at the Predacon base, working on some of the still-sleeping Decepticons/Predacons when he received a call. Shockwave looked over to the computer as he punched a few buttons and said "Shockwave speaking. What is the current situation with the Predacon fossils?" "Knockout speaking. We have retrieved the last Predacon fossil. We're ready to return to base." "Excellent" said Shockwave "Opening Ground Bridge now" as Shockwave pressed a few buttons and pulled a lever. The Ground Bridge opened up, and Knockout, Breakdown, Vertebreak, and Laserbeak came in with the last Predacon fossil. "Where's Hun-Gurr and Airachnid?" asked Shockwave.

"They're still causing that diversion that we told them to do. Those two really wanted to cause as much destruction to the town as possible. We've lost track of them several hours ago" said Knockout. "You know as well as I do why Airachnid is needed" said Shockwave. He turned, then activated one of the still sleeping Decepticons in the Hyperevolution Chambers. The creature's optics onlined as they were a dull red, then began glowing a bright red. He then began growling upon entering the world of consciousness. "Is, is th-that who I think it is?" said Knockout as he trembled as the Predacon roared as the Hyperevolution Chamber opened up. "Yes it is" said Shockwave, before he turned to the Predacon and said "Welcome back to the world of the living. I have a mission for you."

Meanwhile, at the Rescue Bot base, Arcee was playing with Robo-Baby as all the other Autobots came back from their long battle that they had with the Predacons. All of them were seriously injured, and Ratchet was in for a long night of repairs. Only Blades wasn't the one hurt, and he was out. Jack was sleeping on the couch, as Miko stroked his hair while he rested his head on her lap. She was still wearing the same clothes from earlier, and Kade couldn't help but stare at her. Suddenly, the alarms went off at the base, as Chief Burns ran to answer the alarm.

"Chief Burns speaking, what's the situation?"

"This is Mayor Luskey! We have Doc Greene's crazy dinosaur is rampaging across town! Tell him to get over here and turn it off!"

"Ok. I'll have a talk with him, and we'll be right over. Chief Burns out."

Chief Burns then went back down to the main room of the base, and he walked up to the scientist. "Doc Greene? That was Mayor Luskey over the emergency line. He says that Trex is going wild again" said Chief Burns. Doc Greene looked at him and said "Looks like that I will have to repair Trex again. We just need to swing by my lab to get his controller. We'll need Chase to get there." Without warning, Arcee picked up her wings as she stared upwards at a wall, then began growling. Jack lazily opened up one eye, and he had a look of concern on his face. "Jack, what is it?" asked Miko. "Arcee senses something. She would then tell me to get behind her, or beneath her as she would growl at what's before us. It's some sort of ancient motherly instinct that she has" said Jack.

Blades walked into the base with a gigantic white fluffy ball as he said "Hey guys! I found this thing near Doc Greene's lab. I don't know what it is, but it sure is fuzzy." He placed the ball on the ground, and began petting it. "You said that it was near my lab?" asked Doc Greene. "Yes" said Blades "Whatever it is, it sure is warm. The fur on this thing is unlike anything that I touched before. I could pet it all day." Arcee kept on growling as she got into her super-defensive mode, and Jack couldn't help but be frightened. "Jack, what is it?" asked Miko. "Arcee only reacts like that if something bad or dangerous is about to happen" said Jack as he tensed up.

As Blades kept on petting the fluffy ball, it moved. Blades stopped petting for a moment, then began petting it again as it moved again. "Oooh! I hope that it's a kitty!" said Blades happily. Arcee, on the other hand, backed up as she kept her optics on the fluffy ball. The fluffy ball began uncoiling itself, as it took the form of… "Aaaaaaaahhhhhh! A monster!" shrieked Blades as he saw Airachnid's true form. The lamia hissed lazily as she stretched her spider legs. Arcee growled before she pounced on the lamia.

The humans ran out of the way as the Arctic basilisk fought the dragoness within the base. Arcee fought with her blades as Airachnid used her extra spider legs to claw at the dragoness. Using her pedes, Arcee pushed off the snake, then fired her blasters at Airachnid. Airachnid screamed in pain as her fur caught fire, then crashed through the walls as she fled the base. Arcee turned her head at Blades and snarled, then turned around to comfort the crying Robo-baby. She cooed at the little robot as she nuzzled him with her cheek.

Blades stood in shock at what happened, then turned around as he took in what happened. The place was trashed because he brought in Airachnid, as Jack glared at the helicopter. A number of the humans were frightened at what happened, as others just stared at Blades. Blades tried to say something, then closed his mouth, then opened it up again before he did something! He ran! He just turned and ran from the base into the night. "Blades, wait!" called out Dani, but it was too late. Blades kept on running farther and farther away from the base.

"I can't believe that Blades would bring that thing to the rescue station" said Chief Burns as he rode in Chase with Doc Greene. "Neither can I. That thing that Blades brought in would have been a great scientific study" said Doc Greene "But, it was…one of those things that Ratchet warned us about. My Electro-cage generator should lock her up after we pick up my invention."

By the time that the three arrived at the lab, they found Blades there. He was poking at something, with a look of fright on his face. "Blades, what are you doing here?" asked Chase as he transformed. Blades looked at him and said "I decided to come back here. This is where I found…that thing" in shame. He looked back at what he was poking at and continued "When I first picked up…it, I didn't see Trex here. I'm guessing that she destroyed Trex." Doc Greene rushed over, and he saw Trex dismantled. His head was severed from his body, his jaw was several yards away from his head, one of his legs was torn off, his tail broken in several places, and his body was ripped in two. Wires, metal parts, and circuitry were strewn all over the place. In certain parts of Trex were tufts of white fur and a few purple spines. In areas where the spines dripped poison, the metal fizzled and grass burned. "How long was he like this?" asked Chief Burns. Doc Greene studied Trex carefully, then turned and said "From the looks of things, at least five hours." "Five hours? But that's impossible. Chief Burns told me that Mayor Luskey phoned him and said that Trex was rampaging downtown half an hour ago" said Chase. "But that's impossible! Trex couldn't have done it" said Doc Greene. "Not unless that somebody is planning on framing you like last time. And I have a good idea of who it is" said Chief Burns.

Dr. Morocco was waiting outside the rescue station until everybody was out. The calls of a mysterious tyrannosaurus rampaging downtown made the perfect diversion, as the humans left with Ratchet. The medic grumbled on how he had to do the driving, but then again, he was the only one who could leave the base. Once the humans were gone, Dr. Morocco entered the base. He looked around, and he saw Heatwave, Boulder, and Optimus sleeping. He passed them, until he came to the sleeping forms of Predaking and Arcee. Taking out a canister that he had, Dr. Morocco unleashed his nanites. A loud screech caught Dr. Morocco's attention, as it woke up the other Autobots and Predacons within the base. Predaking roared as he woke up, then began screaming as the nanites entered his systems. The screeching woke up Arcee as well, and she began screaming as the nanites entered her systems.

"Dragons! Stop that thing!" shouted Dr. Morocco as both Arcee and Predaking obeyed him and began attacking the screeching creature. All of the loud noises alerted Heatwave, Boulder, and Optimus, as they rushed to the scene and saw the Predacons attacking Jack. Jack kept on jumping, but it was getting harder. Not because the Predacons were fast, but their large sizes made it dangerous as they caused a lot of damaged to the rec room. "I knew that those Predacons would be bad news" said Heatwave as he raised his arms as they transformed and blasted cold water at the two. Arcee and Predaking snarled, as Dr. Morocco held on to Arcee's arm and said "Let's get out of here." The three of them broke through the walls, then flew off into the night. Jack was panting as he collapsed from exhaustion. Optimus picked up Jack as he asked "Jack, what happened?" Jack tried to form words, but he was gasping for air.

Downtown, the humans were staring at a rampaging tyrannosaurus destroying the town of Griffin Rock. Plasma blasts came from the creature's mouth as it destroyed the town. "Dad! We're going to need backup!" called Kade through a walkie-talkie. "On it! I'll be there in six minutes with Chase, Blades, and Doc Greene" said Chief Burns over the walkie-talkie. "I'm not sure if we even got six minutes" said Kade as he watched Ratchet scream as the dinosaur bit his arm.

Blades and Chase made it to the scene as fast as they could, and they saw Ratchet trying to attack the T-rex with his blades, but the tyrannosaur kept on dodging the attacks. "Halt! Your constant roaring is disturbing the peace" said Chase as he tried to stop the dinosaur as he grabbed him by the tail, but the dinosaur snarled before he swung his tail hard, sending Chase flying into a tree. Blades also tried to stop the dinosaur, but it just sent a plasma blast at the helicopter. Ratchet tried to stab the T-rex, but the dinosaur bit down on one of the blades, breaking it.

A low kick knocked down Ratchet, as the dinosaur stared down at Ratchet, then fired a plasma blast at Ratchet before running off. "What was that thing?" asked Cody. "I don't know, but whoever built it must have a background in advanced military technology" said Doc Greene.

When they all returned back to base (Ratchet and Blades took the longest to get back), they found Optimus with a crying Jack as Heatwave and Boulder were walking around in circles. "What is going on?" asked Chase. "It's Arcee and Predaking; Dr. Morocco came by with more nanites, and now they're under his control" said Heatwave. "Hmm…well, I was wondering where he ran off earlier" said Doc Greene. Everybody looked at Doc Greene as he continued "He came by with the mayor earlier, and I asked him about a certain invention in the 'Best Left Forgotten' room. He told me that it was discovered in the mountainside years before the Hall of Inspiration was built. The device was discovered next to that weird fossil that's in the back of the museum." "You mean the griffin fossil?" asked Jack as he stopped crying for a moment as Doc Greene said "Yes." "With the fossils taken from the museum and the mountain, that leaves the device in the 'Best Left Forgotten' room as the only Predacon fossil on the island" said Optimus as Doc Greene said "Yes, but that was taken by the Predacons earlier." "Then, why would they remain?" asked Ratchet. Nobody knew how to answer this, until Frankie said "Come to think of it, it has been several hours since we've seen most of them, except for that spider-snake thing" (Blades looked away in shame.)

Elsewhere on the island, the tyrannosaurus walked as he hunted for what he was searching for. He paused, sniffed, and then headed towards the main power plant. Hun-Gurr was eating at the concrete walls of the plant as the dinosaur roared. Hun-Gurr turned around, then roared back. "It's been too long" said the dinosaur as Hun-Gurr said "Yes, it has." "Shockwave has requested that you return to base" said the dinosaur as the twin-headed dragon nodded, then the dinosaur requested a Ground Bridge. It opened up, as Hun-Gurr looked at it, before proceeding through. Once the bridge closed, the dinosaur looked around as he said "Now, where is that spider Airachnid?"

Airachnid was next to a freshwater river, her burns slowly killing her. Her fur was singed off, and she was bleeding badly. She collapsed from the pain before she could reach it, its cool waters just out of her reach. Her life was pain, it always was from the beginning.

The dinosaur continued to prowl Griffin Rock, but stopped when he heard some roaring coming from above him. He saw two dragon outlines, as a human shouted "Ah, Trex. You'll make a nice addition to my army of robots." The dragons landed, and the dinosaur saw that they were Arcee and Predaking, but something was off. They weren't their usual selves. No, they were in a trance. "Ok dragons, attack!" shouted Dr. Morocco. The dinosaur grinned. He had a few tricks up his sleeves.

Dawn broke out early that morning, and Optimus, Boulder, and Heatwave finished making repairs on Ratchet, Blades, and Chase. The six of them headed off for a long sleep, as they transformed into their vehicle modes to sleep. Upstairs, Jack was awake as he stared at the ceiling. Miko was sleeping on his chest as he stroked her hair. He was unable to sleep since his stepfather and second mother attacked him. They weren't themselves, and now…he didn't know what they were. The rest of the base couldn't sleep easy, and many of them had nightmares or a restless sleep.

The rest of the town couldn't sleep much either, since there was a Tyrannosaurus running around. The said dinosaur was roaming around, and he found Trex's remains. After contacting the base, Shockwave came through. "What is your status on locating Airachnid?" asked Shockwave. "She was here, and she destroyed this Grimlock look-alike" said the dinosaur. Shockwave inspected it, then looked back at the dinosaur and said "This specimen of Earth technology may prove useful. It may help me understand dinosaurs and help me discover what went wrong with the Dinobots. If not…it could be a drone for target practice. Meanwhile, locate your objective." The dinosaur nodded, then resumed his search for Airachnid.

It took a few hours until the call came to the base. "Hello, Chief Burns speaking" said Chief Burns on the phone. "Chief Burns! The power's out all over the neighborhood! Fix it!" shouted Ms. Neederlander over the phone. "Ms. Neederlander, it's a bit too early in the morning for you to be shouting over the phone" said Chief Burns. "I could hear her from here" shouted Jack from the couch.

When Graham and Boulder showed up an hour later, they were shocked at what they saw. Arcee and Predaking were tangled up in some high-voltage power lines, and Dr. Morocco…was charred and flat. Whatever attacked them was powerful enough to take on two Predacons. "We need Optimus and Ratchet here" said Graham as he looked at the two convulsing dragons.

Both Optimus and Ratchet showed up half an hour later, and they were in shock at what they were seeing. "I'm glad that you called us. What happened to them?" asked Ratchet. "I don't know, but the power lines have negated the effects of the nanites" said Graham. Ratchet nodded, then said "We need to get them out of there."

Optimus had to drag Predaking back to base while Ratchet carried back Arcee. Graham had to call the coroner to pick up Dr. Morocco as Boulder assisted him in repairing the power lines. Chief Burns was also called over with Chase to investigate the corpse, and they all noticed some strange dinosaur-like footprints in the ground. They were all over the place, and there were footprints of a second creature. It looked as if some sort of gigantic robot made them, but nobody was able to identify them.
