Dr. Z was dreaming when he heard the cries of a dinosaur he cared for when it was an egg until it was an adult. "My Therizinosaurus is calling for me! Don't worry my child! Daddy's coming!" Dr. Z said in his sleep until he rolled out of bed. As soon as he woke up, Dr. Z went to his dinosaur bones to try to detect the location of his Therizinosaurus. Then as soon as Dr. Z got a strong reading as to where his missing child was, he woke up Ursula, Zander and Ed by unconventional means such as tickling them with robotic arms or stomping them with a giant metallic dinosaur foot. "Can't we just use alarm clocks?" Ed asked drowsily getting out of bed. When the trio were in the same room as Dr. Z, the excited old man was telling them all about his dinosaur. "So you see, I raised Therizinosaurus from when it was an egg all the way into adulthood. What a cute baby." He said. Ursula tilted her head. "Haven't we heard this story before? Except last time it was that Pachycephalo-whatever-it-was." She pointed out. Zander yawned. "Then when we found it, it hated your guts." Zander said. Dr. Z growled and clenched a fist. "That was entirely different! I do see now that I may have spoiled Pachycephalosaurus a bit too much. However with Therizinosaurus, I enforced the strictest discipline. I put that dinosaur through its paces. It trained at night and day to be the best it could be. You should've seen how much that dinosaur appreciated me." Dr. Z cried tears of joy remembering the seemingly happy times that he spent with his Therizinosaurus. Dr. Z pointed to the trio. "Since it's too early in the morning to contact Gabriel, I'm sending just you three to go find my boy. Now fall out!" He said. Suddenly, the floor opened just underneath the trio and they full into yet another flying vehicle. They landed harshly on there seats. "We need seat cushions." Ursula complained. Dr. Z leaned over the ledge of the hole in the floor. "When you get close to the target, look for the colors of the rainbow." He called down.

"Right, the colors of the rainbow." The Alpha Gang trio replied. The giant fan propeller at the front of the vessel whirled to life. The vehicle began to pick up speed as it shot through a tunnel that led outside of Zeta Point. Soon the machine was in the air and off towards the next dinosaur.

The D-Team were climbing some stairs on a sidewalk and a hot day. "Alright guys, let's get this city fossil hunt started! Now this kind of homework I love." Max cheered. Ren had her hoodie tied around her waist today and had her stone in her sweatpants pocket because it was so hot outside. Ren was also carrying a backpack on her with a miniature cooler inside of it holding bottles of water for them and a couple of dishes for the dinosaurs. She even had her hair pulled up into a ponytail. "Agreed, even though it's not my homework, an adventure beats sitting around all day." Ren said. The dinosaurs in their chibi forms crawled up the stairs behind the D-Team. They were exhausted from the heat. When they reached the top of the flight of stairs, all four of the dinosaurs collapsed onto the pavement. The kids turned around. "Come on, don't tell me you're tired already. We haven't even started yet." Max told them. Ren took off her backpack and pulled out the two plastic water dishes and the cooler. She took out one of the bottles of water and poured it into the dishes before screwing the lid back on the bottle. Then, Ebony and Paris huddled around one dish while Chomp and Ace gathered around the other. The dinosaurs all began to lap up the cool water. "Maybe it's a bit too hot out here for them." Zoe suggested. She held her hand above her eyes to block out the sun. Zoe then pointed to a large building. "I bet that shopping mall is air conditioned. After the dinosaurs are done taking a water break, we can start searching there." Zoe told the group. The other three kids nodded in response. "Great idea, Zoe." Rex complimented.

The D-Team soon found themselves walking around the shopping mall. "It feels really good in here after being outside." Ren said. Max joined her up front. "Look at all the cool stuff! Let's go!" He said and began to race off. Ren wasn't too far behind him. "Reduce your voltage, Electro-boy! We should stay together!" She called after him. Chomp and Ebony were right behind them. Unknowingly, they were leaving Rex and Zoe behind. "And there they go..." Rex sighed. Zoe nudged him. "Hey, this way we can find more fossils quicker. Besides how much trouble could those two get into?" She asked.

When Ren caught up to Max, they were a good distance away from Zoe and Rex. "Good. I've finally caught up to you. Now let's go back to the..." Ren started before turning around and realizing that neither Rex nor Zoe were there. "...others." Ren finished. Max turned around to also realize the other half of their team weren't with them. "Where did Rex and Zoe go?" He asked. Ren facepalmed. "It's not where they went, it's where you went. You were so eager that you just dashed off." Ren told him. She followed it up with a sigh. "At least we can cover more ground looking for fossils in separate groups." She told Max. Max nodded. As the two searched for fossils in the walls, Max kept finding himself looking over at Ren. He couldn't believe she was the only one who followed him. The more he thought about it, the more he went back to the thought that it was somehow more calming this way. Ren looked over to see Max looking at her. "Hey, are you ok?" Ren asked him. Max snapped out of his thoughts. "Hmm? Oh yeah. I'm um.. fine." Max stumbled for words as his cheeks were dusted with a light red blush. Ren blinked at him for another moment before going back to looking for fossils. "Hey I think I found one!" She said pointing to the wall. Max walked over to be right next to her. He looked to where Ren's finger was. "Oh yeah! That's an ammonite! They're pretty common, but it's still a fossil!" Max said. Unknowingly to the two kids, Chomp and Ebony ran off. The two dinosaurs walked up to an escalator. Chomp tested it first. The mechanical stairs swept Chomp's foot from underneath him and he began to go up. Ebony bounded onto the escalator just afterwards. Max and Ren turned around to notice their two missing dinosaurs. They looked around before spotting them on the escalator. "Chomp!" Max called as he began to race after them. Ren was right behind him. "Ebony!" She said. When the two kids caught up to their dinosaurs and picked them up, they were exhausted. A sounds of an explosion caught their attention. They looked out the nearest window to see dust flying around a building. The kids looked at each other and nodded before rushing outside.

The Alpha Gang were walking down a street. "I think Dr. Z sent us to the wrong place." stated Ursula. Zander held up the Alpha Scanner showing the location closer to his face. "It says we're here, but no sign of the dinosaur." He said. Ed looked around. "There are no rainbow colors either, whatever that means." He said. Ursula sighed. "Why couldn't his mistakes send us to a beautiful spa and resort? It's extremely hot out here." Ursula went on complaining. Then, she looked up to the tall shopping mall building. "Hey, there's an observatory on the top of that building, I'm sure! We could try to spot the dinosaur from up there!" She said. Ursula clasped her hands in excitement. "Air conditioning!" Zander cheered. Ed perked up spying the tall building. "And snacks!" He said. The trio were off quickly towards the shopping center.

Rex and Zoe decided to take a break. They purchased some ice cream at one of the outside store vendors and sat on a bench facing a window with a pretty fantastic view. There were many stone buildings that were scattered around the city and the light reflecting off of all the windows and cars just made the view even more spectacular. Suddenly, the sun hit just right on their building that it reflected off in a spectrum of colors and hit a spot on another building. "Wow look at that!" Zoe exclaimed as she finished her ice cream. She looked to Rex with a smile as he finished his. Suddenly, a bright light shone from that building and a huge hole was made into the side of it. A dinosaur filled up the space of the light. The two kids hopped up and ran to the window. "No, look at that! It's a Therizinosaurus! You can tell by those massive claws." Rex exclaimed. Zoe leaned in closer to the window. "It's glowing! That's not normal." She pointed out. Rex narrowed his eyes. "Wait, wasn't there another dinosaur that glowed like that before?" He asked. Zoe looked to the blonde and nodded. "Yeah! The Pachycephalosaurus!" She said. They then looked back outside the window. "Wait, is that Max and Ren?" Zoe asked.

Max and Ren skidded to a halt in front of the giant claw wielding dinosaur. "It's a Therizinosaurus!" Max said. Ren took a step back. "Look at those claws. Definitely don't want to be hit by those." She gulped. A shadow loomed over them. The kids looked up to see a blimp and hot air balloon cross like carrier over them. "Right you are! This Therizinosaurus is one of my creations!" said a familiar voice. The two kids looked at each other. "Tell me it's not..." Ren said. It in fact was Dr. Z and he brought Seth with him. Suddenly, a giant purple caged looking thing dropped from the bottom of the blimp. Ren darted out of the way immediately, but after seeing Max hardly budged, she shoved him out of the way, getting trapped herself. The cage retracted, bringing Ren up towards the blimp. "Well we caught one, but her Stegosaurus is still down there. She's useless by herself. Drop her, Seth." Dr. Z told the taller blue haired boy. Seth nodded before pulling a lever. The bottom of the cage opened releasing Ren. "Oh no!" Max said and quickly pulled out his dino-holder and turned Chomp back into a card. "Dino Slash Go Triceratops, ROAR! Chomp save Ren!" Max said and slashed his Triceratops card. Chomp appeared in full size just in time for Ren to land on his back. Ren hugged Chomp. "Thank you, Chomp." She smiled. Ren slid down his back and down his tail safely on the ground. She hugged Max. "You saved me. Thank you." She told him. Max was about to hug her back when he essentially pushed her to the ground "Look out!" He called. Max landed on the ground next to Ren. Sliced up pieces of a light pole went right over them. They would've hit the two kids if they wouldn't have ducked. "That Therizinosaurus is going nuts!" Max said as he got up and helped Ren up. Dr. Z was now on the ground in front of the cage. "Come here, son! Come to Daddy!" He said beckoning the Therizinosaurus to come into the cage. "You miss all the good times you had growing up don't you?" Dr. Z asked. The Therizinosaurus remember the times as a child. They were not good times. He roared at Dr. Z. The Therizinosaurs swung its gigantic claws. Dr. Z darted out of the way, but the cage was obliterated. "What are you doing?" Dr. Z asked the Therizinosaurus. Seth lowered the blimp. "Doctor, I think you've lost control of the situation!" Seth called out from the blimp. Dr. Z turned around to face him. "I have not!" He called. The Therizinosaurus turned around and began to stomp away. "Hey, where are you going?" Dr. Z yelled at the Therizinosaurus. Max and Ren rushed past the old scientist after it. "It's getting away!" Max called.

The Alpha Gang came out of an elevator and straight ahead outside the window was the blimp holding Dr. Z and Seth. "For a minute there, I almost thought that was Seth and Dr. Z" Ed nervously chuckled. Ursula scowled at the rounder member of the trio. "Ed, that IS Dr. Z!" She hissed. Dr. Z was yelling at them, but no words could be heard. He suddenly fell out of the blimp only to be caught by the end of his lab coat by Seth. "I'm afraid these windows are soundproof." Zander said. The whole trio took a step back. "I don't need to hear him to know what to do... RUN!" Ursula said. The trio ran back for the elevator and went down.

It wasn't long until the two kids lost sight of the dinosaur. "Where did it go?" Max asked. The two kids looked around until there was a blinding light coming from the top of a large building. The two kids looked up. "There it is!" Ren exclaimed. Max shielded his eyes from the light. "I can barely see! It's like staring into the sun!" He said. The blimp came around in front of the Therizinosaurus. "My dear boy, why are you running from me?" Dr. Z asked leaning against the sides of the blimp. He then stood up and shook his fists. "How can you resist your own father? Say you still love me! Give me a sign!" Dr. Z told the Therizinosaurus with open arms and a smile. Suddenly, the dinosaur turned and smacked the blimp away with its tail. Dr. Z was knocked out of the blimp. Seth grabbed the back of his lab coat quickly and pulled him back into the blimp. "Dr. Z, it's no use." Seth hissed. Dr. Z sat up on the floor of the blimp. "After all the things I did for you. I will not stand here and let you treat me this way!" Dr. Z yelled at the Therizinosaurus. Seth pulled at the back of Dr. Z's lab coat before he fell over the edge again. "Just let it go." Seth told him. Dr. Z turned to Seth. "Instead of running away, why don't you do something?" Dr. Z hissed. Seth just blinked for a few moments. "I suppose I could analyze the dinosaur." Seth replied before turning to some machinery in the blimp. Seth's pupils shrank when he went to find some weaknesses of the dinosaur. It was more powerful than he thought it was. "Hey! Why don't you just leave that dinosaur alone?" Max yelled to Dr. Z from the ground. Dr. Z peered over the edge and down at the two kids. "You're scaring that Therizinosaurus! I don't think it wants anything to do with you!" Ren called up.

"But how can it be afraid of me?" Dr. Z asked. He turned around to face the Therizinosaurus that had its claws covering up its face, protecting it. "What have I done?" He asked. He remembered the excruciating training and rules he put the dinosaur threw as a child. "B-But I... I just wanted to make you a polite dinosaur... I'm sorry. I just wanted you to grow up to be strong... I thought I was showing you tough love!" Dr. Z said with tears welled up in his eyes. The Alpha Gang walked out of the building and looked up to see the Therizinosaurus backing away from the blimp as it drew nearer. "No way! There really is a dinosaur here! Dr. Z's prediction was actually right!" Ursula said. Ed shook his head. "It doesn't look like a happy reunion." He said. Ursula looked between her teammates. "Let's go." She said. The trio pulled out their Alpha Scanners. "Alpha Slash!" They all chanted together. The three Alpha Gang dinosaurs were on top of the building with Therizinosaurus. They roared at it. "What are you doing? Back off you numbskulls! Therizinosaurus and I are just about to have a break through!" Dr. Z yelled at his henchmen. The three Alpha Gang dinosaurs rushed at Therizinosaurus. The dinosaur slashed its claws at Tank and threw her off the building. Tank turned back into her card on the way back down. Then, the Therizinosaurus began spinning in circles like a tornado with its claws ready to strike. It ran straight into Spiny and Terry. Those two were also knocked off the building and turned into cards on their way down. "It just used Gyro Claw!" Ed said. Max took a step back and kept his eyes glued to the battle. "Man that thing's powerful." He said. Ren nodded in agreement. "I just want everybody to leave my Therizinosaurus alone!" Dr. Z yelled. Suddenly, police sirens were heard down below and a news reporter was on the roof of the building with her crew. The bright lights made the Therizinosaurus charge and then jump until it was climbing up the side of the shopping mall. Chomp raced off after it. "Chomp!" Max called. The small Triceratops ran until it could jump and bite the tail of the Therizinosaurus and hold onto it. "No! This is bad neither of them will survive if they fall." Max told Ren. Ren looked to him. "Then let's help them out." Ren said. The two kids rushed toward the shopping mall and towards the elevators.

"I'm sorry I was so hard on you, my boy. I didn't know! I'll be a better daddy to you from now on, I promise" Dr. Z told the Therizinosaurus as the blimp got closer. Therizinosaurus turned towards it and knocked it away again. "We can't get any closer to him, Doctor." Seth told the short man. Dr. Z growled in anger. "I said that I'm sorry, what more can I do? He leaves me no choice other than to teach him a lesson." He hissed. Seth looked to him. "What are you talking about? Doctor, you've already done enough harm." Seth said. Dr. Z looked up to Seth with tears in the corners of his eyes. "I was only going to have him fall so he'll turn back into a card." Dr. Z said. Seth continued to stare straight towards the Therizinosaurus. "Perhaps, but it's also possible he wouldn't survive the fall." Seth scowled. Dr. Z turned to Seth and shook his fist. "It was just an idea! Oh I don't know what to do. My boy hates me." Dr. Z pouted. He folded up his arms on the side of the basked and put his head down into them. "Let's go get him back." Seth said looking from the doctor to Therizinosaurus.

Max and Ren rushed out the elevator Rex and Zoe were about to go into. "Turn back!" Ren said and pushed her best friend and her brother back towards the large room. Max rushed to the window and pressed his face into the glass. "I'm coming, Chomp! Hold on!" He said. Zoe looked from Rex to Ren. "Chomp? What happened out there?" She asked. Ren looked back at her. "Long story." She said and pulled out her stone. She turned Ebony into a card. "Dino swipe! Stegosaurus, let's rock and roll!" She called. Zoe and Rex looked at each other before pulling out their dino-holders and turning their dinosaurs into cards. "Dino slash! Carnotaurus, blow them away!" Rex shouted. Ace appeared next to Ebony. "Go! Dino slash! Parasaurolophus, bloom!" Zoe chanted. Paris was now in the room at full size. Ace, Paris and Ebony broke the window where Therizinosaurus was. Before the dinosaur could fall, the three D-Team dinosaurs grabbed it with their mouths and dragged it up into the room with them, launching Chomp onto the floor. "Here we go, Chomp!" Max said turning the Triceratops into a card. "Dino slash! Go, Triceratops! ROAR!" Max cheered. Paris, Ace, Chomp and Ebony were lined up ready to take on the opposing dinosaur. The Therizinosaurus roared and suddenly, its claws extended out further. It attacked Paris first and sent her flying into the wall. Paris immediately turned back into a card. It then attacked Ace, sending him flying into a wall of windows. Ace hit the windows with a thud and cracked many of them before turning back into a card. Zoe and Rex picked up their respectful cards and looked at each other with shock. "This dinosaur is super strong!" Zoe exclaimed. Chomp rushed the Therizinosaurus and his horns collided with its claws. Ultimately, the Therizinosaurus outpowered Chomp and sent the Triceratops into the wall. It then turned to Ebony who tried to counter with her tail spikes. The Therizinosaurus also outpowered Ebony and sent her into the wall next to Chomp. Max's dino-holder flashed red, showing that Chomp was on low health. Max and Ren exchanged a worried glance at each other. The extended claws of the Therizinosaurus disappeared. Dr. Z was watching from his blimp outside. "That was Claw Blade. I see you have learned well, my son, my super tough secret dinosaur. But now it's time to listen to your daddy! I'll give you one more chance to come back home with me, ok? If you behave yourself, I'll even play tag with you like we used to do when you were young. Remember? That was your favorite thing to do after a long, hard day's work of training. I used to turn my back on you and you would chase me like this." Dr. Z turned around and pretended to run. Therizinosaurus looked at the doctor and roared with happiness as the dinosaur approached the broken window. Dr. Z turned back around. "You remember! See, we did have good times together! Come give your papa a big hug, my child!" Dr. Z said. Suddenly, the scientist jumped from the basket in the blimp towards the Therizinosaurus. The dinosaur caught him and carefully gave him a hug. "Doctor! Your weight's throwing him off balance!" Seth called from the blimp. Suddenly, Therizinosaurs fell off of the building. Chomp and Ebony rushed up and caught Therizinosaurus in their mouths by the tail. "Pull them back up, guys!" Max called out to the two dinosaurs. Chomp and Ebony began to slip. "Chomp! Ebony!" Both Max and Ren said when they realized that both dinosaurs were being pulled down with the old man and the other dinosaur. "Chomp and Ebony are loosing energy." Max told Ren. Ren's pupils shrank. "That means they'll be pulled down too." She said. Right on cue, Chomp and Ebony fall off of the edge. Max and Ren rushed to the edge of the window and called out for their dinosaurs. Ren took a couple steps back before running to jump down after Ebony. Rex caught her arm. "Are you crazy? If Ebony can't survive that fall, you would stand no chance!" Rex said pulling her away from the ledge. Chomp and Ebony both turned back into cards on the way down. "Let's go down." Max told the rest of the D-Team. They all rushed to the elevator.

Seth deployed himself into a small little flying capsule to try to save Dr. Z. The Therizinosaurus pulled Dr. Z close to him as he leaned back to land belly up. Therizinosaurus was protecting Dr. Z. The dinosaur was nearing the ground right where the Alpha Gang trio stood. Therizinosaurus landed with a thud and turned back into a card. The card landed in some bushes nearby. "You saved my life, my child." Dr. Z said as he hung on a tree branch by his lab coat. Suddenly, Seth swooped in a picked him up and flew off. "Wait! Where's my Therizinosaurus?" Dr. Z called as they flew off.

On the way down the elevator, Max and Ren feared the worse. They both knew their dinosaurs survived the fall by turning into cards, but what if the cards couldn't be found. They both stared blankly out the glass wall on the elevator as it went down. "Guys look!" Zoe suddenly erupted. Both Max and Ren rushed over to her. "Did you find them?" They asked at the same time. Zoe shook her head. "No, but I did find a really big fossil!" She said and pointed to a giant rock that had a very familiar looking dinosaur skeleton embedded in it. The other three members of the D-Team gaped at the gigantic fossil that was right under their noses the entire time. The D-Team got off the elevator and it didn't take too long before Max and Ren found Chomp and Ebony's cards. Max looked over and pulled a third card out of the bushes. "I also found the Therizinosaurus card!" Max cheered.

Back at the Taylor household, the kids showed Dr. Taylor the picture Zoe took of the fossil they found. "This is excellent! You kids really did a bang up job on your project. I'm very impressed." Spike said. Max smiled and looked between everyone else before returning his focus back to his father. "Thanks, Dad. Hey, do you know what kind of fossil that is?" Max asked. Dr. Taylor studied it. "Hmmm. Looks like it could be in the same family as Tyrannosaurus... but if I had to guess..."

"A Therizinosaurus?" The kids all asked at the same time. Dr. Taylor looked up at them. "Well that would make sense. That's also the dinosaur that appeared in the city today." He said. Max held up the card. "Yeah and it was pretty powerful too." He said. Zoe nodded. "Even with all four of our dinosaurs, we couldn't do too much against those claws." She said. Dr. Taylor looked to her. "Artificially strengthening a dinosaur the way they do is very dangerous and irresponsible." He said. Rex chuckled. "Yeah, after all your own dinosaur could turn against you." He said. Ren giggled. "Serves that old geezer right." She said.

"You can say that again." Zoe laughed. The D-Team found themselves in laughter after another successful mission.
