Smaug startled Rainbow and Indominus by punching them in the air, The attack caught the fighters and spectators by surprise. Indominus didn't think that Smaug was capable of using his arms to attack while trying to stay airborne. Smaug dropped a few feet, but easily spread his wings out and was flying again.
"This dragon is just full of surprises," Rainbow said to Indominus after the sneak attack.
"He's definitely got more brains than Black Death ever did. Regardless, we'll still beat him."
With one beat of his wings, Indominus was going after Smaug again. The dragon lord swung another punch at him, but Indominus was ready for this one. The scaly fists collided against each other and sent shock waves echoing across the sky. While the spectators were being rattled by the collision, the dragon and dinosaur shared a smile at each other. They were both pleased with how the fight was going, and Indominus decided that his girl deserved a chance to show her strength.
Indominus pushed himself off of Smaug's body, and flew back as Rainbow Dash came speeding forward. Smaug saw the mare coming and zoomed towards her with another punch ready. This time Rainbow met the attack head on with her clawed hoof. Smaug was surprised when he got the same powerful shock waves after his fist collided with Rainbow's hoof. It amazed him how a pony could be just as powerful as a dinosaur hybrid. The dragon lord wanted to see what else the two lovers were capable of.
He flipped his body over and smacked Rainbow down with his tail. Smaug used the momentum to follow up with another punch as Indominus lunged at him. All three fighters were heading out of the sky and back down into the volcano. Smaug shut his wings to gain speed on the falling warriors, but Rainbow and Indominus were one step ahead of him.
The couple brought back their red auras, zoomed straight to the ground and then bolted skywards back towards Smaug. At the rate the warriors were going, there wasn't enough time for Smaug to dodge the attack. Rainbow dealt him an uppercut to the face and Indominus hammered his fist into the damaged chest armor. The force from the hits knocked more air and blood out of Smaug's mouth, and the dragon growled in frustration. As he struck the couple in retaliation, Smaug's attack left bleeding scratch marks across their faces as they hit the ground.
Indominus staggered back to his feet, feeling more dazed after the attack. As he walked over to Rainbow Dash, he felt his legs getting shaky and unsteady. Rainbow was also having trouble standing up, Smaug's blow had gotten them good. They turned their heads when they heard Smaug touch down on the platform.
"Looks like I've finally managed to get through your tough hides. While I can't transform like you two, I can increase my strength. That last attack will leave you both feeling rather weak for awhile."
"Oh you think so?"
Smaug was appalled by Indominus's retort, then stared in shock as the red auras returned and healed the marks his attack had left behind.
"We've still got a few tricks left Smaug, and being able to heal during a fight is one of them," said Rainbow. Smaug bellowed a very frustrated roar and charged towards the winded warriors. Rainbow was about to brace herself when Indominus stepped ahead.
"I got this one Rainbow, you take a minute to heal yourself."
"Alright, I trust you know what you're doing Indominus."
The hybrid barreled towards Smaug and began building up strength in his right fist. He had a feeling that Smaug was also gathering strength for another powerful punch. The dragon lord had a look of pure anger on his face, likely from all of his attacks being outdone no matter how hard he attacked them. The carnivores drew closer to each other and once Indominus was within striking range, Smaug drew his fist back and prepared to attack with all the strength he could build up. The dragon lord and hybrid swung their fists at each other, but the collision produced a rare and unexpected result.
As the fists collided, Smaug watched as golden flames erupted from in between his fist and Indominus's. Indominus witnessed the spectacle too, and was shocked as the flames began to circle and surge around his body. What astonished the hybrid most, was that the golden fire seemed to be focusing solely on him and not the dragon lord. Smaug had wide eyes and he was shaking at the sight before him; what he was witnessing was a legend he didn't think was possible.
The dragons above had bulging eyes and dropped jaws. Everything in the gauntlet had blown their minds, but this spectacle was the icing on the surprise cake. It was one thing for Indominus and Rainbow to be on par with Smaug, but to see the dinosaur with gold flames around him was far beyond what they had expected. The Mane Six were also in just as much shock, Twilight had never seen anything so astounding in her life.
"I've never seen anything like this before, this goes beyond anything they've ever shown," said Twilight.
"What in the ever lovin' apple barrels is happenin' to Indominus?"
"The flames around him are almost like the ones Philomena had. How is something like this even possible Twilight?"
"You're asking the wrong pony Fluttershy, I'm still wondering how the dinosaurs are able to transform in the first place."
"From the looks of it, Dashie is the one that seems the most surprised out of us all," said Rarity.
She couldn't have been more right, Rainbow Dash had the widest eyes out of everypony else. She had a front row seat to the action along with Smaug, and shakily stepped forward to get a clearer look at her fiance.
"Indominus, what's happening to you?" The hybrid slowly turned around and Rainbow's jaw hit the floor as she took in the hybrid's new look. She could see new, different marks within each of the flashes of golden flame that wrapped around her fiance. The hybrid didn't know what to think of the new change himself.
"I-I don't know," Indominus said as he looked at the gold flame that flickered around him. This is far different than the power you gave us against Black Death. I don't even understand how a power like this can be achieved." Smaug's shocked tone caught Indominus's attention away from his new look.
"Y-You...are...the one. Indominus, you have the potential to become a true legend."
"You know what's happening to me Smaug?"
"What you're seeing is only a glimpse of the form's true potential. I've seen it only one other time, but you are definitely on the right track. It's a form I call the Immortal Phoenix, and it's as rare as the stone you chose for Rainbow's ring." Smaug was so eager to see what Indominus could do with the flames around him, and he was about to get his wish.
"Well, let's see what this glimpse of true potential can do."
Indominus exploded off the ground and lurched forward at Smaug, the speed was blinding to him and before he knew it, the hybrid was going into the sky while carrying the dragon lord. It all happened so fast that the spectators only saw a flash as Indominus went past them. The hybrid quickly reversed direction and threw Smaug back onto the platform with incredible speed. The dragon crashed and landed on his back, Indominus touched down by Rainbow who was smiling at how fast her fiance had been.
"Phew, these flames are giving me more of a kick than I thought."
"I'll say, with those gold flames around you, you can move as fast as I can," Rainbow said happily. In fact, I have an excellent idea that'll put them to good use."
"I'm listening."
While Smaug was recovering from the speeding impact and getting back to his feet, Rainbow whispered her little plan of attack to Indominus. The hybrid hung onto his girl's every word and when she was done, he had a devilish grin on his face.
"That is such a wicked idea Rainbow Dash, I love it! Let's put it to the test."
Rainbow kick started her aura and she and Indominus prepared themselves for their surprise attack. Smaug had just gotten back on his feet when he saw Rainbow and Indominus speeding towards him again. They rammed his body and drove him against the wall of the volcano. They fighters then began forcing him up the wall and into the air, where they began dealing another volley of fists and blasts. Smaug swung his claws and tails all over the sky to hit them, but Indominus's new flames had made him much faster. He could block and intercept every attack the dragon lord threw at him.
Rainbow took advantage of the situation and nailed Smaug in the back. As he fell, the dragon lord grabbed Indominus by the leg and punched at him on the way down. Once they were back inside the volcano, Smaug chucked Indominus at the platform. This time however, the dinosaur landed on all fours and immediately bolted for the sky. He rammed Smaug head on, but continued to climb skyward. Rainbow followed after him until the two of them were golden yellow and red dots in the sky.
From their high point of view, Rainbow glanced at her fiance.
"Alright Indominus, we're about to find out if this works. If it doesn't, we'll most likely end up as splotches inside the Final Destination."
"I know Rainbow, but if it does work then we've won the gauntlet." Indominus took Rainbow's hoof and looked her dead in the eyes. Regardless of what happens, we'll still be together."
The two shared one kiss before they opened their jaws and began building energy within them. Everypony below could see the energy building and the lightning surging out of their mouths. Twilight's eyes went wide at what she thought Indominus and Rainbow had planned.
"Everypony! Be ready to move! Rainbow and Indominus are going to launch their blasts!"
Smaug heard what Twilight said and started to get nervous. If they unleashed their attacks from such a height, then the energy would ignite the volcano and engulf everything in the area. His common sense began telling him otherwise the more he thought the situation over.
"There's no way they would fire such devastating blasts from up there, those two would wipe out half the dragon lands if they did."
Rainbow and Indominus clamped down on the balls of power stored in their mouths and held them. They glanced at each other, nodded their heads once and began diving towards the ground. With the amount of power they had, their speed was building at an incredible rate. The Mane Six could see the mach cone already forming around Rainbow Dash, and the golden flames were forming a spear around Indominus. Scootaloo's eyes shrunk as she realized what her sister and savior had concocted.
"Everypony! We need to fly now!"
The dragons didn't hesitate this time, they took to the sky with the Mane Six and CMC and began putting as much distance as possible between them and the volcano. They still kept an eye on the diving warriors, who were becoming more engulfed by the power surrounding their bodies. This was going to be a Sonic Rainboom to end all Sonic Rainbooms.
Down in the volcano, Smaug was rooted to the spot. All he could do was watch as the warriors continued to gain more velocity. The red aura and golden flames had engulfed them completely, and he could hear the mach cones reaching their peak. Whatever they had planned was about to take place.
"Let's see what you and your mate have in store for me Indominus."
Then everyone heard the tremendous explosion.
BOOOOOOOOOOOOOOOOM!!!!!!!!!!
The Sonic Rainboom was triple the size of an average one. The golden flames and red aura had both been added to the mix, giving the Rainboom a much more sinister appearance. What scared everypony most was that none of them could see Rainbow or Indominus. After the Rainboom happened, both fighters had disappeared from view. All they saw was a red and gold lightning flash that dove into the volcano and vanished.
Smaug had shrunken eyes and a dropped jaw upon seeing the spectacle. He had no idea where either of the fighters had gone. He had watched the whole thing, and they had simply disappeared from sight. He had no idea however, that disaster was waiting right in front of him. He heard two crashes on the platform and as he lowered his head away from the Sonic Rainboom, his heart sank.
Rainbow and Indominus were right in his face at point blank range. The orbs glowing in their mouths with hundreds of lightning flashes. There was nothing that could prepare Smaug for the devastation he was about to endure.
"NOOOOOOOOOOOOOOOOOO!!!!!" Smaug's scream was drowned out by the roars of the warriors as the blasts erupted from their jaws.
The spectators all heard the thunderous roars and felt their hearts drop as a massive explosion burst from within the volcano. Tons of lava erupted with the blast and expanded along the entire width of the volcano. The volcano's crater was being expanded and destroyed by the sheer power that Rainbow and Indominus were pouring onto Smaug.
"They were capable of that kind of power!?" The green dragon was so shocked as he asked the Mane Six and CMC and witnessed the power destroying the volcano.
"I didn't think that their love for each other would be able to produce a blast of this caliber," said Scootaloo.
"There ain't no way in heck that Smaug will be able te walk away from an attack that strong," said Applejack.
Sweetie Belle added, "I'm wondering how they managed to pull off an attack that fast. I've never seen Rainbow Dash pull off a Sonic Rainboom that fast."
"I just hope they're alright," Fluttershy added.
"Looks like we're about to find out," said T-Rex.
The eruption died down and the spectators flew over to the widened crater to try and see what had happened. The inside was covered in black smoke and lightning strikes could be seen floating around the area. As the smoke cleared, they could make out two bodies that were glowing. The Mane Six had wide eyes and the CMC were astounded at the sight.
Indominus and Rainbow were panting heavily and their energy was continuing to surge around them. Indominus still had the little golden flames circling his body, and they seemed to have grown in numbers. They had done a serious number on Smaug, who was lying face down in the dirt as the smoke cleared up completely. The dragons were all mortified by what incredible damage had been dealt to their king.
Many of his scales had been peeled away from the force of the blasts. The skin near his wings was blistered badly and blood was spilling from his mouth and pooling around his face. Seeing that he wasn't budging or making any movements, it was obvious he had been truly devastated. Many of the dragons thought that Rainbow and Indominus had done the impossible: they thought the warriors had killed their king.
Each of the spectators held their breath nervously, hoping that their king would somehow be able to get up from the brutal attack.
