Scootaloo returned to the crash site with a golden yellow crane and a sky blue ambulance. Scootaloo changed to robot mode. The ambulance transformed into a sky blue robot with yellow arms, legs, and head with pink metallic hair. She also has red crosses on her shoulders. This robot is Fluttershy, the Canterbot medic. Taking the hook from the crane, Fluttershy went to help Rainbow Dash. Scootaloo went with the medic.
"Where did they get you?" Fluttershy asked.
Rainbow recovers to answer her. "I..uh..I think it was my...my drive train."
"Can you transform?"
"I....I don't think so."
As Fluttershy hooked up Rainbow Dash, Scootaloo sadly went to her fallen friend. "I'm sorry, Rainbow Dash. It's my fault. I shouldn't have fired on Grogar."
Rainbow chuckled weakly. "You...Shouldn't have missed you mean."
"Huh?" Scootaloo soon felt a little better. "Yeah. Right!" She then called to the crane. "Big Rig, pull her up!"
The crane started to pull up the fallen Canterbot warrior. Meanwhile, looking out at the desert is a teal robot with lavender arms and head, and dark purple legs with black feet. She has a purple helmet with pig tails. This is Aria Blaze, one of the Tambelocon seekers. She is joined by a trio of look alike gray robots with black helmets. One of which has a lens on its chest.
"I can't believe that the Canterbot survived." The trio said in unison.
"Huh! Neither can Grogar." Aria replied roughly. "I though he'd blow a fuse when he found out."
Suddenly, she sees something tracking across the desert. "Hey. What's that?".
The triplets also see the movement. "Let's find out."
The trio transformed together into a camera, and landed in Aria's hand.
"Okay, Raptorian." Aria said as she aims the camera. "Let's see what you can see."
The seeker soon took a picture. She then looked at the picture with interest. It was of a four wheeled vehicle. Back at the Tambelocon base, Sombra received a message. Aria Blaze to Sombra. Aria Blaze to Sombra.
As Aria continued to watch the movement, she hears Sombra responding. Proceed, Aria Blaze.
"Alien vehicle approaching." Aria replied. "Possible Canterbot."
At the base, Grogar gives an order. "Release Dark Scratch!"
Minutes later, the vehicle stopped in front of the wrecked power station. Two male workers came out rto survey the damage.
"I don't understand it, Joe." One worker said. "Looks like a tornado hit this place."
"I...I don't like it." The other worker replied. "Something's wrong. Really wrong."
Suddenly, they were jumped by a black mechanic panther. After they were pounced on, the men went back to their vehicle, and drove off. The panther's eyes glowed red. Meanwhile, back the Canterbot base, Rainbow Dash gave out a report while being worked on.
"And, that's all we heard, Twilight." Dash said. "They're going to put the energy in some kind of cube then, haul it back to Equestria."
Twilight Sparkle then turned to Starlight Glimmer. "Starlight, organize a battle unit. We're going after them."
Outside, the Canterbots were ready to go. Starlight soon called for the volunteers. "Sunset Shimmer!"
Sunset soon swirved her lower body to let her transform into a police car. Scootaloo transformed into her scooter mode.
"Bulk Biceps!" Starlight called out. Bulk converted into a white van.
"Micro Chips!" Starlight continued. Micro raised his arms and locked them above his head as he laid back to transform into a race car with the number 539.
Starlight continued her role call. "Applejack! Trixie Lulamoon! Rarity!" A white curvy robot with midnight blue hair converted into a luxurious car. "Sweetie Belle!" A young red robot with white legs, arms and head, and a helmet in swirls of pink and lavender converted into a red car.
"Canterbots," Starlight said, "start your engines!" The vehicles soon revved up as she turns to her leader. "Ready, Twilight."
"Let's roll!" Twilight commanded.
The Canterbot leader transformed into her truck mode. Starlight quickly switched into a teal race car with a yellow '6' on it. Soon, all of the Canterbot vehicles rolled off to fight their enemies. Meanwhile, the evil hawk, Shadow Squawk, returns to the Tambelocon base. Sombra approached his leader with vital information.
"Grogar," Sombra reported, "Shadow Squawk has returned. He has found a source of energy."
"Excellent." Grogar replied pleasingly. "EXCELLENT!"
At an oil rig, many men and women work to keep the oil rig going. One of the female workers, Megan Williams, looks at an area, and calls out to someone.
"Give me a hand, Danny." Megan said. "We need to raise this bit. Flush it out!"
"Right, sis." The young man replied. "I'll get the bailer."
From the skies, Grogar leads his troops to the oil rig. "Dive! Dive!"
The workers see these giant robots invading.
"Look! Up there!" Megan shouted as the Tambelocons landed. "What is it?"
"What are they?" Danny added.
"Everybody. Come on!" Shouted one of the workers.
The workers started throwing small tools at the invaders. But, obviously, no damage. Grogar picked up a steel pipe, and rolled it towards the workers. They dodged it, some of them dove into the water. Garble grabbed Megan, which made Danny mad.
"Stop!" Danny said with force. "Let go of my sister!"
Danny tried to fight back. Garble pushed him back. When Danny fell in the water, Megan pushed her attacker away to rescue her brother. "Danny!"
As Megan dove in to save Danny, Grogar gave a command to one of his seekers.
"Adagio," Grogar said, "activate your null ray. Now!"
Adagio Dazzle fired a ray to paralyze the machinery. Grogar then turned to his communicator. "Sombra, prepare the Energon cubes!"
From his chest compartment, glowing cubes came out, one after another. The Tambelocons filled the cubes with oil. Soon, they smashed some cube stacks down. The cubes started to glow.
"We did it! We did it, Grogar!" Adagio cheered. "The energy is ours. We can go back to Equestria!"
"You fool, Adagio Dazzle!" Grogar protested. "This is just a small fraction of the energy we need. We must suck this planet Earth dry!"
Adagio then saw something in the sky that scared her silly. "It's the Canterbots!"
Indeed it was the Canterbots heading for the oil rig. Grogar gave an order to his troops. "Tambelocons, transform! TRANSFORM!"
Grogar soon shifted his body into a rifle with a scope. Adagio caught the rifle and fired it at the Canterbots. They dodged the fire and charged after their enemies. As Twilight Sparkle came along, Grogar changed back to robot mode to confront her.
"Don't interfere, Twilight!" Grogar said brutally.
"Give it up, Grogar." Twilight replied.
"The universe is mine!"
Micro Chips and Garble fired at each other high above the rig. Applejack and Adagio Dazzle fought each other with steel rods. Fights broke out everywhere. Sonata and Raptorian gathered cubes. They zipped off before Sunset and Starlight caught up to them. As Twilight battled Grogar, Shadow Squawk started pecking at Twilight so his master can escape. With energon cubes in hand, the Tambelocons left the rig.
"So long, Twilight Sparkle." Grogar said as he aims his fusion cannon. "Have a nice swim!"
He fires at the rig, breaking it into pieces, the Canterbots and humans slid off the rig. But, Grogar isn't done yet. "Here's something to keep you warm!"
Grogar fired at a storage tank, setting the area of fire. He laughs viciously as he and his Tambelocons escape. Soon, the voice of Megan can be heard. She and her brother are trapped behind a grate.
"Help! Help!" Megan called. "We can't get out!"
"Somebody!" Danny added. "Save us!"
Twilight swims over to help as Megan continues to panic. "The fire! It's coming closer!"
"I..I can’t lift it." Twilight said, trying to lift the grate. "Too heavy." She turns to the people she's trying to rescue. "Grab on to me. Keeps your heads above water."
With the rig area erupting in flames, the Canterbots hope they can rescue the workers.
