Link
Link and Reaper flew the entire rest of the day. They flew in one straight direction, without ever slowing down. Reaper sensed the urgency in his rider, and flew as fast as he could. The dragon did not know why Link needed to go so fast, but he was happy to do so. For once, Link did not feel like flying upside down. The duo continued on in silence, Link praying he was not too late.
Finally, Link could make out the distant continent of Hyrule. It did not appear to be covered in Malice. Sure enough, it was just the same as it had been before he left. Link urged Reaper onward toward the castle. Reaper expertly dodged each laser the guardians fired at them, unphased by the danger.
The pair flew directly into the sanctum. Inside was a cocoon, but unlike butterfly cocoons that felt beautiful, this purple cocoon felt repulsive. As soon as Reaper's claws touched down on the marble floor, the cocoon began to thrash about.
A golden glow covered the cocoon, and Zelda's voice called out, "Link...Link! I'm sorry… but my power isn't strong enough… I can't hold him…" As Zelda finished her sentence, a blue laser shot out from the cocoon. It weaved its way around the room, singeing the floor. It did not hit Link or Reaper, but that was just lucky. There was nothing either could have done if it did. The cocoon abruptly ruptured, and Calamity Ganon fell from the hole. The Calamity was a disgusting monstrosity. It had six legs and a large abdomen like a spider or an insect. It's head looked like a living skull, with glowing orange eyes. The beast carried a large axe, spear, sword, laser gun, and pincers. Every inch of its repulsive body was covered in slimy Malice. The monster was too heavy for the floor, and it collapsed, taking with it Calamity Ganon and Link. Link easily caught himself with his paraglider, and flew down to confront the monster he was destined to battle. Reaper hesitated, slightly scared. The dragon looked into his rider's eyes. Instead of the usual playful glitter, that was present even when Link went on raids and suggested the young boy thought of life as nothing more than a game, there was a ferocious feral rage. This was not a game anymore. This was it. Reaper made up his mind and flew to assist his new companion in this ultimate fight. Boy and dragon landed directly in front of the monster, and Link unsheathed his sword. The Master Sword practically hummed with power, the usual steel blade now a glowing sky blue.
Link could feel rage coursing through his body. The Spirit of the Hero that lived in him came alive. All the rage of Link's past lives, their struggles against Ganon or Ganondorf or Demise, made Link tremble from his newfound fury. All of the different Heroes over the ages were ready to assist the current one in defeating the Calamity however they could. Link felt himself become stronger, faster, and more agile. He glared at Calamity Ganon, and the beast saw pure rage coming from the boy. Then the ground began to shake, and Link could feel the spirits of the Champions preparing to have their Divine Beasts fire at Ganon. One by one, Link felt through the ground each laser fire, and they met at the top of the sanctum. They combined into one super laser, that rained down upon Calamity Ganon. The evil monster reared and screeched in pain. The screech sounded like nails on a chalkboard. The laser continued for as long as it could, but it ran out of power, and shut off. After the smoke cleared, Link and Reaper saw Calamity Ganon sprawled out on the floor before them. All was still, and the two waited in bated breath to see if the beast was truly dead.
Then the Calamity stirred, and dragged itself to its feet. It turned to look its enemies in the eyes once more, then brought down its axe. Link jumped out of the way quickly, and ran forward, slashing with his sword. Ganon pulled his axe out of the floor, and Link retreated to a safe distance. Reaper hovered in the air, bombarding the monster with blasts of fire. Calamity Ganon seemed to not notice the barrage of fireballs raining down upon it. It only payed attention to Link. This time, the Calamity swung its axe sideways, and Link backflipped over it at the last second. Link's magical ability, the flurry rush, activated and time slowed for everyone except the Hylian. Link raced forward, and slashed with the Master Sword at the beast. After a few seconds, time caught up with the boy, and Link once again retreated.
Reaper, meanwhile, was confused. His friend had been a few feet in front of the monster a few seconds ago, but had somehow teleported directly in front of it.
"One of my magical abilities," Link explained to his bewildered dragon, "called the flurry rush."
Reaper merely nodded, not completely understanding, and continued bombarding Ganon with blasts of fire. The Calamity took no notice of the new cuts it had received from Link's slashing. The monster simply shook itself off, and paid no attention to the streams of Malice flowing from its body in the place of blood.
"This guy's not going down easy," Link commented, dodging another axe swing. Reaper nodded in agreement. "Well, neither are we."
Calamity Ganon had apparently had enough of Link's game of tag. It pulled its axe from the ground again and scurried up the wall like a monstrous spider. The beast closed its eyes as though concentrating, and suddenly several large ice blocks appeared in front of it. One by one, the ice was sent floating slowly towards Link. Link remembered this attack from the monster on board Mipha's Divine Beast. "Reaper! Shoot the ice blocks!" Link commanded. Reaper did as he was told and fired a blast at each of the approaching ice blocks. As soon as fire met ice, the block disappeared, and Link was not hit by a single one. "Way to go, Reaper!" Link called. Reaper roared in triumph. But Calamity Ganon wasn't done, and it crawled along the wall, and got as close to Link as possible. Then it jumped, and Link narrowly avoided the energy beam that shot out from the Calamity's feet as it landed. Ganon stood up again, and raised its axe. Link prepared to jump. But, as the axe swung across the room, Link waited just a second too long, and the axe smashed into his side, throwing the Hylian across the room. The blade was too large and too thick to be sharp, so Link was not cut. Even so, pain erupted in his side as he lay sprawled on the floor. Reaper immediately stopped his assault on the monster, and flew to assist his friend. Link struggled to stand up, certain he had broken more than a few ribs. Calamity Ganon scuttled over, and raised its axe. Link was not ready to give up. As the axe came down, Link rolled out of the way, ignoring the pain that exploded in his side as he did so. Link summoned his magical infinite inventory bag, and dug through it, searching for a fairy. Reaper resumed attacking the Calamity, knowing there was nothing he could do to help his injured companion. Link couldn't find what he was looking for.
"Must've used my last one when I got hit by that lynel earlier," Link muttered to himself. There was nothing he could do. He would have to fight injured. The destined swordsman pulled himself to his feet, his face contorted in a snarl. Calamity Ganon surged forward, sensing the enormous pain his adversary was in. It swung its axe sideways again, and Link ducked. Link weakly swung the Master Sword, only hitting the monster once before being forced to retreat. Calamity Ganon continued attacking, and Link was left with no time to attack the beast.
Link was struggling. The pain in his side persisted, seemingly getting worse with each swing of the Master Sword. Calamity Ganon was sensing his pain, and was only becoming more and more relentless in its attacks. Despite the pain and the huge enemy he faced, Link pushed on. He knew he had to defeat the Calamity. For the princess. For Hiccup and Astrid. For the whole world. Link remembered his nightmare from a few nights ago, and knew he couldn't let that happen. Newfound strength poured through the chosen hero's body, and the pain lessened. As Calamity Ganon swung his axe downward, Link sidestepped, activating his flurry rush. Link rushed forward, and swung the Master Sword, over and over again. Ganon reared and screeched in pain. Link smiled to himself. The monster retreated up the wall, and Link heard Reaper charging up his blast to deflect the ice. But this time, the beast raised its blaster, aimed it at the dragon, and began charging.
"Reaper hold your fire!" Link called. "And run!"
Reaper quit charging, and flew as fast as he could. Calamity Ganon fired its blast of wind toward the dragon. The blast missed by inches, but Reaper was flying too fast, and crashed into the wall. Reaper shrieked in pain, the same cry that had brought dragon and rider together so many weeks ago. "Reaper!" Link yelled, and ran to his dragon. Reaper stood up, and shook himself off. He held his wing at an awkward angle, and Link knew the poor dragon had broken several bones. The mighty Dramillion would be grounded for the rest of this fight.
Link turned on the monster he was destined to fight in wild anger. "You have taken everything from me!" Link screamed at the beast. "You took my all my friends; Princess Zelda, Mipha, Daruk, Urbosa, and Revali! You took my memory of everything I ever loved! You almost took my life! But you're not done yet, are you? Taking everything I loved before wasn't good enough was it? Now that I have new friends and a new life, you're determined to rip everything away again! Well, I won't let you! I won't let you take my dragon! I won't let you take my new friends! I won't let you take this world away from me!" Link finished, screaming in pure, untamed rage. He roared and charged Calamity Ganon, all fear for his own safety gone. This ended now. No one else was getting hurt.
Ganon was not expecting the sudden anger of his opponent. The monster was unable to raise its axe to block the flurry of attacks coming from the furious hero. Even so, Ganon kept its composure, and snapped its pincers at Link, who nimbly sidestepped them, activating the flurry rush again. It was Calamity Ganon's turn to be mad. This boy, whom he'd defeated 100 years ago, was back somehow, and turning out to be much more of a threat than the monster had expected. Calamity Ganon decided to pull out all the stops. The monster reared up, and Link was forced to stop his fierce attacks. A bright orange light pulsed from the beast, the force of the blast knocking Link off his feet. Link struggled back up again, pain once again exploding in his side. Calamity Ganon now glowed a neon orange. Reaper stopped his barrage of fire for only a second, slightly surprised, then continued his endless beast glared at the hero, daring him to come closer.
Link glared right back, and charged once again. This time, Ganon was ready. As Link got closer, the monster raised its oversized axe. When the Hylian was within range, the beast swung the axe horizontally. Link attempted to slide under the weapon, but he was too late, and he was flung across the room again. Link screamed in pain, and crumpled to the floor. A phantom of the Zora Champion, Mipha, appeared over the hero's body, and Link's eyes flashed open, all his injuries still hurting. Nonetheless, the hero pushed himself to his feet, his eyes clouded and pained. Link's face was contorted into a grimace, and he struggled to stand on his own. Reaper hopped to his rider's side, gently helping him stand up. But, the Calamity sensed the Hylian's weakness, and rushed forwards, the axe raised. Reaper barely pushed Link out of the way, activating the flurry rush, but the hero was in too much pain to utilize it. Link was barely able to keep himself upright. Time caught up with him, and Link ducked under the giant axe. However, he lost his balance, and fell on his face. Ganon ran forward, pinning Link on the ground with his slimy legs. Reaper shrieked in worry, and hopped to assist his companion. Calamity Ganon slammed the axe into the oncoming dragon, and Reaper fell limp, his body flying through the air, and smashing into the wall. The force of the impact shook the entire room and probably the entirety of Hyrule Castle.
"No!" Link cried, unable to move. The Malice covering Ganon's body began to take effect, and Link felt his life being sucked away. The edges of the swordsman's vision began to fade, and Link knew he had failed. "I'm sorry Zelda... I'm sorry, Hiccup... I'm sorry, Reaper." The last thing Link saw was Calamity Ganon raising its axe above its head, and then everything went black.
