Kiryu skidded to a halt besides Arstron, the kaiju glaring at the mecha as it came to a halt on his left. Kiryu nodded to the male M.U.T.O. Arstron narrowed his eyes before nodding to the mecha and turning back on the M.U.T.O. Kiryu activated both wrists blades, metal swords extending before being charged up with maser energy: making both blades glow yellow. Arstron charged up another heat ray, his dorsal plates beginning to glow. The M.U.T.O roared before flying straight for the two. Arstron fired his heat ray, covering Kiryu as the mecha leapt forward into the air. The M.U.T.O dodged to the side of the heat ray; flew to Kiryu, flew out of the way of the mecha's mid-air blade air strikes before grabbing Kiryu by the neck, swinging around to the mecha's back and then bashing it into the power plant ruins.
"Gyaaarrrh!" Arstron jumped at the M.U.T.O and delivered a punch to its face, sending the kaiju crashing down. Arstron landed and twirled around whilst charging a 2nd heat ray. As the M.U.T.O rose out of the flames, Kiryu dashed to its side and roundhouse kicked it straight towards Arstron. The heat ray shot forward. The M.U.T.O was sent flying straight back to Kiryu. Kiryu jumped up and kneed the creature in the spine before Miku brought the mecha's left elbow down on its throat. As the M.U.T.O was sent tumbling towards the ruins below, Kiryu dashed to Arstron whilst firing a volley of missiles from its back that went straight for the downed M.U.T.O. Explosion after explosion raged out with each missile that flew through the fire and flames. Kiryu turned back around. Arstron got ready. The M.U.T.O slowly rose up into the smoke filled sky as the nuclear energy was siphoned into its body, granting it more power. Arstron wasn't bothered.
"Of course... these battles are never quick... I was hoping to avoid combat today... but..." Miku muttered.
'Stepping it up?' Kiryu's AI inquired. Miku nodded.
"Activate synchronisation mode." Miku commanded as the control panel before her shifted into the floor. She stood up, her seatbelt coming off and her chair joining the control panel below. A circular platform shifted into action below her, glowing as a sync-mode activated: Miku's mind linking up with Kiryu's AI. "It's clearly a Mutant kaiju..." Miku frowned as a force field zapped up around her from the edge of the platform beneath her: metal clamps going into place on her feet as the winds that rose up from belowblew her hair around. The pupils in her eyes going from blue to red. Miku clenched her fists. "Let's put it in its place. I have no more mercy to give to kaiju like that, not after all that's happened." Miku adopted a fighting stance, Kiryu assuming the exact same stance in perfect harmony with her. A fiery red aura engulfed Kiryu as the ground exploded around the mecha. Arstron shot Kiryu a curious look. The M.U.T.O was taken back by the display. Memories of 1954 flowed through Miku's mind, memories of 2004 flowing through Kiryu's mind. The two sharing each other's pain. The original Godzilla's bones had long been removed from Kiryu, but the good in Godzilla 54's spirit remained. A hologram of Kiryu appeared around Miku.
'let's go...' Kiryu's words were projected as a hologram of their own before Miku. Miku performed a dashing motion, kept on the platform by the metal clamps, and Kiryu rushed forward: thrusters spewing out blue flames. The mecha shot straight past Arstron in the blink of an eye, leaving behind an afterimage. Before the M.U.T.O could dodge out of the way, Kiryu uppercutted the kaiju high into the sky, flying after it in pursuit. As the M.U.T.O flipped through the air, Kiryu reappeared above it to deliver an energy-engulfed dive kick to its chest: a burning trail left in the mecha's wake.
"AAAARRGGHH!" Miku pulled back her left arm. Kiryu delivered a left hook. "GRR!" A right hook. Another left. Right. Left. Right. Left. Right. Left. A lightning fast flurry of punches. Miku lifted her right leg up, metal clamp rising up on a multi-jointed stilt. "Go for it, Arstron!" Miku's voice projected from Kiryu. Kiryu performed an axe kick on the M.U.T.O's face before dashing behind Arstron as the Mutant rocketed downwards. Arstron jumped up and performed a back-flip kick to the M.U.T.O's neck. Kiryu kneed it in the face. Arstron delivered a right hook. Kiryu karate-chopped its right elbow after grabbing its arm. Arstron sent it tumbling along the field with a tail-swipe to the face. Chunks of ground flew everywhere as the M.U.T.O tumbled along before crashing through a line of trees. Kiryu and Arstron stood side by side. Arstron narrowed his eyes. Kiryu and Miku's eyes glowed in tandem. The M.U.T.O stumbled back up. Kiryu and Arstron shot one another a look. They nodded. Arstron broke into a run as Kiryu's thrusters lifted it up off the ground. The M.U.T.O wished it could widen its eyes. Arstron went in with a right hook, Kiryu in with a left. Both struck at the same time. Kiryu dashed to the M.U.T.O's left as it flew back, Arstron jumping to its right. Oral maser cannons charging up, Miku performing a kamehameha-style stance as the command, as Arstron readied a heat ray. Kiryu was suddenly sent flying back as Cyber-Zilla bashed into the mecha and Arstron was then bashed away by MechaGodzilla. The M.U.T.O rolled along the ground as Cyber-Zilla and MechaGodzilla skidded to a halt on either side of the creature. Kiryu and Arstron stumbled back up. "What the...?!" Miku growled. "Oh come on, we had this one! Where did they even come from?!" Before the M.U.T.O could get back up on its feet, MechaGodzilla tossed the same kind of device that had been previously imbedded in Legendary Godzilla's tail by none other than Cyber-Zilla onto the M.U.T.O as it laid slumped down to the mecha's left. The M.U.T.O finally got back up and roared at the Vortaak's puppets before taking to the skies: retreating from the battlefield. "Oh no you don't!" Kiryu went to pursue the Mutant but Cyber-Zilla jumped in the mecha's path. MechaGodzilla turned to Arstron.
"Gyaaarrrh!" Arstron didn't back down. Nothing but scrap to him.
"Let's call in the big guns..." Miku narrowed her eyes.
'Affirmitive.' The mecha activated a beacon, relaying the signal to GDF HQ. A call for more firepower. Kiryu's weapon pack.
