Back at Smash HQ, two Miis, a Brawler with a red hoodie from the fourth tournament and a Mii Force Gunner, stood watch over Ganondorf's cell, which had been transferred to the top level. Inside, the warlord had his arms crossed patiently. A hologram of Dr. Light, from Mega Man's world, stood over the Miis.
The male Gunner sighed. "Remind me again why we're doing this?" "The Smash Stone's power must be harnessed properly." Dr. Light answered. "An overdose would be far beyond your control and would possibly destroy you. If the pieces prove to be too powerful, we must find a solution. Thus, if Miis such as you wish to have that power, a weapon must be built so that your kind can use it."
"Rhetorical question, doc, but thank you." the Gunner remarked, switching off the hologram before turning to the Brawler. "Hey, can you pass me that coupling there? On the top shelf?" The Brawler nodded and broke into a run. Upon reaching the wall, he jumped up and launched off an adjacent wall to snatch the component.
"You know, Ryu or Little Mac could teach you a few moves, like that jumping uppercut or that diving haymaker…" The Gunner suggested as the Brawler tossed him the coupling. "Yeah, I'm good, thanks." The Brawler said, holding up a hand. "I'm pretty sure my exploding kick move is pretty OP."
The Gunner's earpiece quickly chimed. It was from Tails, who was on rooftop duty with Dark Pit. "We've got movement, seven klicks out." The fox announced. "It's a whole bunch of Jet Primids. Get the shield ready."
Dark Pit drew back an arrow as Tails set up his blaster into its sniper configuration. "Shield charging. T-minus sixty seconds to full power." The base's A.I. informed. Dark Pit fired arrow after arrow as Tails pulled the trigger, hitting incoming Jet Primids with green lasers. One shot hit a pack, causing its occupant to crash into another and fall onto the grass below, close to the main entrance. A few more zoomed past the two. "You've got incoming!" Tails shouted into his earpiece as he kept firing. "Bring 'em on!" Dark Pit yelled at the oncoming horde. "Unlike the elf, my arrows never run out!"
"Intruder alert. Multiple hostiles detected." The A.I. said as the Gunner strapped on his arm cannon and loaded his ammo. The Brawler stepped forward in a defensive position as a Primid landed and charged at him. The Brawler vaulted over it and kicked it in the back before sweeping another's feet from under it. The Gunner advanced, shooting any Primids that got within range. He kept himself from using missiles or grenades, afraid he might damage the systems or the unfinished weapon.
"Hee-yah!" the Brawler shouted as he grabbed a Primid, used it as a shield against another's laser rifle and threw it a few more. The Gunner lined back-to-back with the Brawler as they both took down the incoming wave with laser fire, punches, burst shots and kicks.
Back on the rooftop, Tails and Dark Pit were doing their best to keep the incoming wave at bay when a blue energy field surrounded the entire Smash HQ, causing four Jet Primids to crash into it. "Shield activated." The A.I. informed. The Primids remaining pulled back, took out their rifles and began shooting at the shield, with some using rocket launchers to try and bring it down.
"Good work, Miles. Take a break and bring the black angel with you." The Gunner told Tails as the shield continued to hold. "I could use one." Tails sighed as he and Dark Pit left the roof, but not after the angel tried to shoot down some targets, only to fail.
"Shield at eighty percent. At current rate, collapse is imminent." The A.I. warned as the base's alarms blared. The two Miis seemed worried on what to do next. "Alright," the Gunner brought up. "Does anyone have something useful to…" "Shield at sixty percent." That warning made him a bit nervous. "We're on our own here." the Brawler said, turning to Ganondorf's cell. "We need him. We gotta let him free." The Gunner noticed what he was trying to do. "Um, what's that word I'm looking for?" He said sarcastically. "No?"
"Shield at forty percent." In his cell, Ganondorf chuckled. "Something funny, grimace?" the Gunner threatened, readying his cannon. "Your kind is the most advanced race in the multiverse, yet you rely on your own inventions to protect you. This barrier cannot save you." the warlord stated. "Release me." The Gunner frowned at him, but before he could say anything back, the A.I. spoke up. "Warning. Shield at twenty…"
A portion of the main window crashed, making both Miis turn to face the intruder. When they saw it, they froze for a brief second before engaging.
The Gunner fired blast after blast at the intruder, only for it to raise a murky black hand to absorb the shots and release its own at him. The shots caused the Gunner to stumble back and crash through a table. The Brawler sprinted forward and tried to land a flying kick, but the intruder caught his leg, flipped him and delivered a strong punch that sent the Brawler clean through the wall.
"Ganondorf." Master Core spoke. "I see you have traded one prison for another. And yet you refuse to submit to me." "And refuse I will, like I did when I realized Tabuu had played me like a puppet since I joined." The warlord retaliated. "If one is destined to rule Hyrule one day, it shall be me." Master Core dashed up to Ganondorf's cell with inhuman speed until he was face-to-face with the King of Darkness. "You have served your purpose from more than a decade ago." The being said, remembering Ganondorf's time in the Subspace Army. "Soon, the power of the Smash Stone will be mine, along with each and every dimension. Tell me, warlord, how does it feel to know such power, and…"
"Hit it! Now!" The voice made Master Core turn to see that the Miis had recovered. The Mii Gunner had ripped out an electric cable and plugged it into his cannon and the Mii Brawler had switched off the base's power system. As he did, the Gunner fired a massive plasma beam at Master Core, which made the being stumble away from the cell.
The cell was covered in a cloud of dust and a dark figure moved through it. Ganondorf, now free, charged at Master Core with his fist glowing. The punch knocked him back, but Master Core fired a beam from his hand, which Ganondorf blocked and countered by slashing his heavy sword at the interdimensional being. Master Core transformed into his beast form and pounced at the dark lord, who grabbed him, slammed him to the ground, picked him up by the tail and threw him. Master Core recovered by transforming back in midair and summoning five blades made of Subspace itself.
Ganondorf used his own sword to block and parry the floating blades, cutting them apart as he advanced. Once the last blade was gone, Master Core prepared to unleash a shockwave that would turn Ganondorf into his trophy state, but Ganondorf rolled under another beam attack, this one with two hands, and stabbed Master Core through the torso.
"GRRRAAAAAHHHHH!" Master Core yelled as a pulse wave sent Ganondorf skidding back with his arms in a blocking position. As Master Core stood, his entire body seemed unstable as a purple glow started to spread. "N-no… how can this be?" he stammered in shock. "I have never… I cannot be defeated. More… powerful… I must become more powerful… I must retreat… and heal…and…I will finish all of you…"
In a purple flash, he was gone. All remaining Primids also retreated at once as the base's alarms quickly calmed. "Well…" the Gunner muttered. "That could have gone much better."
