“Soundwave, if you drain this planet of its energy, it will die!” Optimus protested. “Cybertron is lost! Let it go! Why destroy one planet to restore the life of another?!”
“BECAUSE THIS PLANET IS INFERIOR WHEREAS CYBERTRON IS SUPERIOR.” Soundwave coldly replied. “OUR HOME WORLD SHALL BE BORN ANEW, AND YOU AUTOBOTS AND PONIES SHALL ALL PERISH.”
As he said this, he brandished his dark energon axe and swung it horizontally to send a powerful wave to take out the Autobots. Optimus protected himself and his friends by using his shield. The impact of the hit, however, pushed the last Prime several distances away from Soundwave until he stopped.
“BRUTICUS, ATTACK AND DESTROY!” Soundwave commanded.
“I thought you would never ask!” Bruticus replied with delight knowing he’ll finally have his own deadly fun with the Autobots. He drew forward while he drandished his copper blades and flamethrower. Several Autobot troopers opened fire on Bruticus, but the blasts had no damaging effect on his armor. Bruticus moved forward toward them and started sucking the energon out of them. The energon flew out of their bodies in the form of gas and was swallowed by the titan.
“Hmmm! Delicious!! Autobot energon seasoned with fear!” Bruticus gloated. “Now all of you weak heroes shall stay for dinner!”
“Autobots, take cover! Fall back!” Optimus quickly commanded.
They all retreated as ordered. Prime and the Autobots had another challenge that proved itself even more difficult than with Menasor. If they were to get to Soundwave, they would have to overcome Bruticus first.
As the Mane 7 saw this, they were shocked. The combiner reminded them of Lord Tirek who devoured magic. Only that this Decepticon was ten times more deadly than the centaur. They had to find a way to help the Autobots defeat him.
“How are we going to get past this guy?!” Rainbow shouted. “He’s got to have some weakness.”
“How? He’s too powerful!” Rarity doubted.
“And huge!” Fluttershy whimpered.
“You know what they say, ‘the bigger they are, the harder they fall’!” Rainbow encouraged. “Optimus, any ideas?”
Optimus looked onward behind Bruticus who was burning the houses in search of the ponies and Autobots. He saw Soundwave activating the pillar and it starting to send a magnetic blast to absorb Equestria’s magic. He then knew what to do as he thought of an idea.
“Time is short! I need a distraction! Rainbow Dash, Pinkie Pie, you will assist the Dinobots in distracting Bruticus while I handle Soundwave and disable the pillar.” Optimus ordered.
“How can we take him down if he will immediately suck our life force? He’ll kill us all easily!” Swoop questioned.
“I’m not asking for you to take him down yet. I’m asking for you to draw his attention so he won’t notice me.” Optimus clarified.
“Well, it will be a valiant effort.” Snarl conceded.
“Yeah, we will make sure to cover for you.” Grimlock said. “Come! There’s no time to waste!” he directed his crew.
The Dinobots left with Rainbow and Pinkie as they were about to arrest the combiner’s attention. Optimus then turned to everyone else. “The rest of you will buy us some time! Look out for any Decepticons!”
“Got it!” they all complied.
Optimus nodded his head and transformed into his vehicle mode as he drove behind the piles of bodies, fire, and smoke. Bruticus was successfully distracted by the Dinobots and two ponies who were throwing insults at him. He angrily unleashed his firepower on them but they managed to dodge and escape every assault directed at them. Fortunately, he never noticed the last Prime passing behind him.
Soundwave was finished with managing the controls of the pillar. He beheld his work as the pillar was then absorbing the planet’s energy. He looked forward to see Cybertron reinvigorated to its former glory. He knew that Megatron would’ve been pleased if he was present.
But his enjoyment was interrupted by a laser shot that touched his shoulder. He looked behind and saw Optimus transforming to robot and approaching him with his energon axe.
“TRYING TO SAVE THESE PATHETIC CREATURES, PRIME? HOW AMUSINGLY PREDICTABLE.” Soundwave mocked.
“Freedom is the right of all sentient beings, Soundwave. Taking the life of one world to save another is a grave crime against nature, against creation, and against morality.” Optimus lectured.
“SPARE ME THE SENTIMENTAL LECTURES. YOUR CONCERN FOR THESE FLESH BAGS ARE BENEATH MY CONSIDERATION. THE MISSION IS ALL THAT MATTERS AND CONSEQUENCES ARE IRRELEVANT.” Soundwave wickedly stated.
“I will not allow you to destroy them!” Optimus shouted before running to the Decepticon villain to fight him.
Soundwave unsheathed his dark energon axe once again as he began to fight the Autobot leader. Both leaders struck at each other with their own axes, swung at each other, skillfully dodged each other’s attacks, and shot at each other.
Soundwave leaped into the air while raising his axe to strike him. Optimus countered his attack by punching him in the face. Soundwave fell on his back. Prime raised his axe to end him. But Soundwave attempted to trip him, but Prime jumped over his leg and attempted to pound him. Soundwave raised both of his legs to kick Prime off. Prime stumbled from the kick.
Soundwave swung his axe producing his wave of dark energon. Prime countered it with his shield blocking the wave from hitting him. Soundwave swiped a another one. Prime leaped over it as he was charging at him. Both axes collided once again.
“AT LAST, WE DECEPTICONS SHALL TAKE OUR RIGHTFUL PLACES AS LORDS AND RULERS OF THIS UNIVERSE. WE SHALL POSSESS THE POWER OF THE COSMOS.” Soundwave boasted.
“You are nothing more than a prisoner of Megatron’s twisted delusions!” Optimus said.
“NEGATIVE. I AM A FULFILLER OF MEGATRON’S DREAMS OF CONQUEST.” Soundwave corrected.
Soundwave kicked Prime off as he swung his axe yet again. Optimus jumped out of the way of the destructive wave. The wave though did manage to accidentally take out the vehicons that attempted to help their master.
Optimus got on his feet as he readied himself again to face his opponent. Both fighters collided their axes and tried to each other’s head off but they were too fast for each other.
However, Soundwave slowly got the upper hand. As soon as Prime swung his axe at him, the villain dodged his attack, duck under Prime’s arm while dodging, and struck his shoulder pad with his dark energon axe. Prime grunted in pain.
For one last time, they both swung their axes. But suddenly, Soundwave’s axe broke Prime’s axe, shattering it to pieces. Prime was taken back at this. While he was distracted, Soundwave punched him and kicked him on the waist. He then smote him on the back to bring him down.
Optimus grunted in pain from Soundwave’s assaults. He tried to get up but couldn’t. Soundwave then landed his foot on Prime’s chest as he savored his apparent victory.
“AND SO, THE LAST OF THE PRIMES FALLS. SOUNDWAVE SUPERIOR, OPTIMUS PRIME INFERIOR.” Soundwave exulted.
“NOW IT ENDS, JUST AS MEGATRON ENVISIONED. YOUR HEAD SHALL BE MY NEW TROPHY!” Soundwave boasted. He raised his axe as he was about to execute the leader of the Autobots.
Suddenly, a huge magical blast struck Soundwave on the back. He looked behind and saw Celestia, Luna, Twilight, and Cadence together glaring the Decepticon. Soundwave took his sight off of Optimus as he faced the alicorns.
“SO YOU HAVE COME TO SAVE HIM? YOU FLESHLINGS ARE QUITE AMUSING. PERHAPS I SHALL ELIMINATE YOU FIRST.” Soundwave taunted.
“Leave Optimus Prime alone, Decepticon! You and Grogar cannot win!” Twilight defied.
“AND WHAT MAKES YOU THINK YOU WILL SURVIVE AGAINST US?” Soundwave asked.
“The fact that you never learned to mind your surroundings.” Celestia said while smirking.
“WHAT?” Soundwave said confused. As if to answer his confusion, a huge explosion erupted behind him. It threw Soundwave off guard as he was thrown against a building. Moments later, he lifted himself from the debris. As soon as he lifted up his face, he saw Optimus standing with his drawn blaster and the pillar completely disintegrated. All the energy that the pillar was absorbing immediately returned to the planet’s core.
“NOOOOO!” wailed in his monotone vocoder.
“You’re finished, Soundwave!!” Optimus shouted. He shot at Soundwave’s visor to disorientate him. He ran as fast as he could before ejecting his energon sword and stabbing Soundwave right through his chest and out of his back. Soundwave staggered as he tried to take Prime’s face but couldn’t. Then at that moment, all of Grogar’s magic left him. His wings faded into dust, his axe disappeared, and his visor flickered until his spark was extinguished. Prime retracted his sword as he witnessed Soundwave’s body falling on the hard ground. His corpse exploded.
The Autobots and ponies arrived at the scene after they defeated Bruticus. The Combaticons and Breakdown were shocked to see their leader dead. They fled to Grogar as they told him everything. Grogar was enraged after they finished their report.
“The alicorns are no longer under my control?! How is it that you failed to kill the Autobots and those ponies?! I just finished my business with Daring Do and Cabellaron then I hear all this?!” Grogar angrily reprimanded them.
“We’re sorry, Lord Grogar, sir!” Breakdown whimpered.
“The Autobots overwhelmed us! We couldn’t—!” Vortex uttered before Grogar spoke again.
“SILENCE!! Your failure to wipe out the enemy is unacceptable! And now, I shall trip my power from you.” Grogar denounced. He rang his bell and its dark magical waves drained them all of his magic. They fell on the floor weakened. Grogar turned his back as he then made an evil smile. “Don’t worry, Soundwave, I shall avenge your death by painting this entire throne room with Prime’s energon.”
After the heroes reunited with the princesses and Prime, the latter set his optics on the castle.
“It’s you and me now, Grogar.” Optimus said.
