Deadpool was currently trying to eat a slice of pepperoni pizza through his mask, which was only resulting in a very greasy chin and a lot of muffled swearing. He tossed the crust toward a trash can (and missed) before grabbing the mic.
"Alright, tum, hope you brought some marshmallows because it's about to get incredibly toasty in here!" Deadpool shouted, his voice cracking with excitement. "We're leaving the skyscrapers behind for a place that's basically a giant barbecue pit. It's the battle of the bad boys with big appetites! The pink-haired pyro vs. the blonde demon captain! It's Dragon Slayer Magic vs. Full Counter!"
The arena shifted into the Volcanic Crags of Magmell. Massive rivers of glowing lava flowed between jagged, black obsidian pillars. The air was thick with ash, and every few seconds, a geyser of fire erupted from the ground.
Heimdall was hovering on a cooling rock, looking slightly singed. "Semi-Finals Match Seventeen! The Fire Dragon Slayer of Fairy Tail, Natsu Dragneel! Versus the Dragon's Sin of Wrath, the leader of the Seven Deadly Sins, Meliodas!"
Fire and Counter-Fire
Natsu slammed his fists together, a massive explosion of flames erupting around him. He had a wild, toothy grin on his face. "I'm fired up! I've never smelled a demon that smelled like... leftovers before! Come on!"
Meliodas stood calmly on a piece of floating rock, his broken sword resting on his shoulder. He looked bored, as if he were waiting for a pub to open. "You're pretty loud for a lizard, kid. Let's see if you can back it up."
Natsu lunged forward, his feet propelled by jets of fire. "Karyū no Tekken!" His fist, engulfed in a massive fireball, swung right at Meliodas's face.
Meliodas didn't dodge. He simply flicked his wrist. "Full Counter."
The fire didn't just stop—it doubled in size and blasted directly back into Natsu's face. The explosion sent the Dragon Slayer flying into a pillar of obsidian.
Dragon Force vs. Assault Mode
"Deadpool here! Don't count the pink kid out yet, tum!" the merc screamed. "Natsu literally eats fire for breakfast! He just took a nap in his favorite snack!"
Natsu emerged from the smoke, but he looked different. Glowing red scales were appearing on his skin, and his aura was turning into a literal dragon of flame. He had entered Dragon Force.
"Karyū no Hōkō!" Natsu unleashed a roar of fire so powerful it turned the lava below into steam.
Meliodas realized he couldn't just play around. His eyes turned a deep, pitiless black, and a dark, shadowy mark appeared on his forehead. Darkness swirled around him, forming a suit of armor and wings. He entered his Assault Mode.
The two clashed in mid-air. Natsu's fire met Meliodas's darkness, creating spheres of purple and orange energy that shattered the obsidian pillars like glass. Natsu was faster, hitting with a barrage of "Crimson Lotus" strikes, but Meliodas's physical strength was overwhelming.
The Final Roar
Natsu gathered all his magic into a single point. "Shiranui Gata: Guren Hōō Ken!" He became a spear of golden fire, flying at Meliodas like a comet.
Meliodas didn't use Full Counter this time. He drew his true sword, Lostvayne, and created four clones of himself. Each clone held a different stance. As Natsu struck, all five Meliodas's combined their power into a single, concentrated burst of "Enchantment: Hellblaze."
The black flames of the demon king met the golden fire of the dragon. For a second, the entire arena went silent. Then, a massive shockwave leveled the volcanic field.
When the smoke cleared, Natsu was on the ground, his magic completely exhausted, though he was still trying to crawl forward. Meliodas stood over him, his demon mark fading, looking down with a small, respectful nod. "You've got a big heart, kid. But I've been doing this for three thousand years."
"Match Seventeen winner... MELIODAS!" Heimdall proclaimed, as the volcanoes gave one last, weary puff of smoke.
Up in the booth, Deadpool was trying to light a cigar off a stray spark. "That was metal! Pure, unadulterated metal! Seventeen down, tum! We're heading into a real 'size matters' fight next."
Deadpool checked the list and his jaw dropped. "Oh boy. It's the Prince of all Saiyans vs. the King of the Monsters. Are you ready for Match 18: Vegeta vs. Godzilla?"
