Trunks rolled his shotgun in hand and blasted a golden expulsion of Ki toward Gohan. The hunter of the resistant element of humanity put up his hands to block the attack. Future Gohan's arms bent a few degrees from the forceful impact but the enhanced Saiyan held his own against the blast, forming his own Kiai field around him that brought Trunks' attack forward a few inches, preparing an uppercut with his free hand to knock Trunks' attack away while his cybernetic one handled the blast.
A sharp snap noise made Gohan's vision race behind him. Trunks slid in from the back, having vanished behind his opponent and moved in from a nasty angle where Gohan having a way to defend himself was the most unlikely. The hunter from the future grunted in pain while Trunks drove right past Gohan, flipping him up in mid-air while Trunks grabbed hold of the Ki blast with his hand and swung it around his axis, popping his shotgun open and slamming the Ki blast right back into the chamber with the Ki mass reducing in size to fit.
"Together we'll save my future from you, Gohan!" Trunks turned to his off-balance opponent and aimed his shotgun point-blank with a resolute expression. Gohan exclaimed in pain when the shotgun went off, detonating the Ki blast right up in Gohan's face and blasting the cybernetically enhanced hunter away from him.
Wrathful Chayote grumbled, taking off in a coating of emerald Ki and racing around the airborne Gohan in a wide arc. She flopped her belly and chest out to smack into the enemy coming her way, having outpaced Gohan to the location where he'd have soon been. A ring-shaped shock wave of aerial pressure expanded from the point of impact as Chayote sent Gohan bouncing back toward her pursuing Super Saiyan partner.
Trunks let out a triumphant battle cry as he swung his sword in a static, up to down angle as if attempting to slice clean through his opponent but Future Gohan spread his arms out, creating a barely visible, lemon-colored force field around him which took the brunt of the sword slash for him. Twirling his sword in one hand, Trunks drove it down again after spinning it horizontally around, gripping its hilt with one hand, Future Trunks brought it upward, busting through Gohan's force field and slashing into the hunter's face and his cybernetic vizor, expelling dark cherry-colored blood and sparks alike.
The sword went back in swiftly and with a slick click, Trunks brought his right with a crunchy thud, switching the punching hand with another cross, just as resonant and vociferous. The attacking arms switched again, then again, then again, becoming near-automated and speeding up rapidly until Trunks' combination of punches became a blinding flurry as the two traveled diagonally upward. Having abused his own arms to the point of numbness, Trunks rolled over in mid-air and brought his hands together, slamming them down with a double ax barrel slam and smashing Future Gohan down into the ground.
"I'll eliminate you here, Gohan, then I'll liberate humanity from 21! Burning Attack!" Trunks proclaimed as his hands went through a rapid switch of arm positions until Trunks settled on having his arms crossed over his chest. Sealing his bold proclamation, Future Trunks extended his hands with his thumbs and index fingers, touching one another and his hands forming a diamond-like shape. A golden energy sphere, radiant with light all over, fired from his hands, hurrying toward his underground and ruffled opponent.
The golden sphere detonated shortly before reaching Future Gohan, expanding into a blinding dome of radiant heat. The intense light even made Chayote cover up even though she's been observing the technique from the sidelines and not taking the brunt of it. It seemed as if though the nova of pure energy would envelop everything and reduce it to rubble, but just before the blast became too intense; it peaked and began drawing back. The aftereffects died out in a flash, leaving just trails of smoke and a blizzard of pelting pebbles.
"Eliminate me?" Gohan hissed, crawling out from the rubble and rising back to his feet. "Are you sure you want to show your back to your partner here? She doesn't seem to be in her right mind…"
Chayote grabbed hold of her head, wrestling against her own rising energy and surging violent impulses. Just as Trunks turned to her and before he spoke a single word to soothe her, the Wrathful Saiyan took off in a dash toward Future Gohan. Chayote plunged with both her feet aiming down as if preparing for a dive underwater from a tall ledge. An agonizing grunt filled the fighting stage as Chayote dived through solid stone, bringing her opponent along for the ride.
It looked as if Trunks' attack had already caused some serious damage to Future Gohan as it had damaged Gohan's Gi and left him scratched, burnt, and bruised. It felt unfair to the rising fighting spirit of Chayote's that the ruthless hunter from the future still had all of his limbs attached, so she sought to correct that. Just as the floor of bedrock beneath her feet felt too tough to dive-bomb her opponent through, Chayote stomped, deepening the crater again and again. Proceeding until a scorching, hot-red sludge burst forth from underground.
Gohan rolled off of the geyser of magma and slammed his elbow into Chayote's jaw. The exceptional impact shattered his damaged vizor, revealing white, bloodshot eyes with teal irises underneath and static, angular, cybernetic patterns over the whites of his eye. The Saiyan from the future flinched in surprise when Chayote's jaw barely moved a few inches to the side and the wrathful monster smirked. Gohan immediately hid amongst a crowd of afterimage duplicates as he snapped further away from imminent and grievous bodily harm.
"Your mind tricks won't work on me anymore!" Trunks revealed himself to have positioned not too far away on ground level from where Gohan had retreated off to. "Can't you see? Chayote has finally learned to take control over her transformation and she's no longer a threat to her allies. It's both of us against you–you're through!"
"Is that so?" Gohan replied with bitterness in his tone. "It's true that Chayote's gains in power while in that form surprised even me. But for how long do you think she can maintain that control she's worked so hard to learn?"
"You won't set foot in God's Temple in this timeline. Piccolo will make sure that your counterpart is safe from Bardock's influence. I'll stop you here and now. You've failed!" Future Trunks prepared to dash forward with a firm grip on his sword.
"Humph, I've had it up to here with your self-righteous yapper…" Future Gohan's face twitched as he turned to Future Trunks and aimed his hand at him. His Ki formed a turbulent aura around Gohan that spun around Gohan with jets of dust before minuscule particles of energy forming around his cybernetic arm cannon. "Good thing is, you're half Artificial Human yourself, so I don't need to leave much of you intact to still be able to question you."
Emboldened by Future Gohan turning his back at her, Chayote bellowed in mindless wrath and opened herself wide, spreading her arms and feet out as a shining, golden energy bubble blinked in around her. Little by little, it began taking a more salad-colored hue as more and more of Chayote's energy produced by her Wrathful State transformation surged inward.
"Fava Nova!" Chayote roared out, rushing toward Future Gohan alongside her meteor-sized energy field.
"You idiot!" Future Gohan yelled out, turning around with his flesh and bones arm grabbing the wrist of his cybernetic arm. "Super Kamehameha!"
"You're the fool here, Gohan!" Future Trunks took off just as the Kamehameha collided with Chayote's energy field and began a heated struggle with it. One that Future Gohan seemed to be losing as step-by-step, Chayote was continuing her forceful strut onward and pushing the Super Kamehameha back.
"Don't think I forgot you either," Gohan coughed out, extending his biological arm and firing a flashing energy wave toward Trunks that stopped the advancing Super Saiyan in his tracks by clashing against his drawn sword and started a secondary struggle.
"When I get my hands on you…!" Chayote grumbled, taking one forceful and bold step at a time as her Fava Nova proved itself to be an impenetrable force field that worked well enough against Gohan's strongest Kamehameha.
"Didn't you hear… What I told you?" Future Gohan replied with forceful grunge to his tone. "Your measly wrath, the joy of victory and grief of loss… All those pathetic human feelings are just chemistry for me to play with! I'm the one who truly mastered all those emotions you've tried to control your entire life, Chayote!"
"What's that Ki?" Trunks' gaze widened as the golden Ki leaking out from Future Gohan's body began taking a humanoid shape and stand up like a titanic, ethereal man behind him. "It can't be… Son Goku?"
Trunks' terror proved to be based in cruel reality as the golden aura around Son Gohan took clearer and clearer shape of his late father up to the facial features and spiky, Super Saiyan hair. The ethereal shape spread its arms and legs out as if performing a double Kiai in all directions. This boost of unparalleled power made Chayote halt and Trunks' sword let out painful cracks as the damage across the large blade became more severe. Chayote put up her hands in front of her, feeling her Fava Nova struggle to keep up with the sudden burst of fatherly energy overloading both techniques with sheer force.
"My grandfather had an uncanny ability to boost his power beyond its limits by experiencing the loss of a dear one. As you've become painfully aware… Grief is just a cocktail of the right chemicals to me…" Future Gohan ground it out through grit teeth as his body seemed to overclock to keep up with the additional boost of energy. "Now… Both of you can disappear for all I care!"
"W-Wait… If Chayote dies…" Trunks tried to force his final words out shortly before his sword broke with a forceful pop and shattered into metallic splinters while Gohan's energy wave engulfed Trunks whole and began burning up his attire and littering his body with heated bruises while the Super Saiyan's eyes whited out and his long hair soon fell by his sides as Trunks lost consciousness. This left Future Gohan with a free hand to boost the Father-Son Kamehameha he was pushing Chayote's advance off with.
"What? This universe will end? You twit, this isn't my universe, nor is it yours. The fate of this Chayote is of no difference to us. It'll be poetic if you disintegrate along with the rest of this timeline though since you went through all this trouble for it and all…" Future Gohan replied to an unconscious body before both he and the ethereal Ki avatar in the shape of his late father exclaimed their final, proud battle cry and Chayote saw cracks in the Fava Nova shell while azure light began seeping through.
The devastating beam punched through the last of Chayote's resistance, coloring the entire world around her cerulean and whiting Chayote out as she desperately struggled to swim through the dominant influx of energy washing her way. The overwhelming energy wave didn't wait for Chayote and its remnants beamed off and left Earth's orbit, finding other cosmic bodies in its way to obliterate before it dissipated halfway across to another galaxy.
Gohan panted lightly, lowering his mechanical arm that shot off herds of sparks in all directions from various busted parts in it, prompting the hunter from the future to clutch his precious mechanical replacement firmly with his hands as the trail of golden energy faded away, leaving just his normal Super Saiyan aura to shimmer in a controlled gleam.
"That's not a very nice thing to say to someone…" a low-pitched grumble made Gohan stagger back as the smoke from his immense blast settled and clear the supermassive crater it had left in the wastelands of the ruined mountain range. The image of Chayote standing tall with only the minimum tatters to protect her dignity and her bruised yet very much bulked out body.
"You… Survived?" Future Gohan coughed out. "Impossible, how!?"
"It didn't hurt to have Fava Nova shielding me until the bitter end but… I guess the main reason is - you're just a piss-poor weakling!" Chayote's right eye widened in a psychotic glint as she roared and charged ahead, placing both her arms behind her back and leaning down, letting the painful draw closer to the ground and collapse from her wounds carry her onward.
Before Chayote could get her hands on the still-recovering enemy of hers, an iron-tight, frigid grip locked around her whole body. Tiny, feminine limbs barely long enough to even wrap around Chayote's biceps and thighs fully. One hand covered up Chayote's mouth and at that very instant the Wrathful Saiyan felt her energy leaving her body as if being vacuumed away somewhere else.
"About time reinforcements came." Future Gohan straightened his back out and tried to keep up a facade of coolness to him, as if he had expected this surprise development all along when in fact he had abandoned the hopes of his signal reaching anyone curious and willing to pitch in a short while ago. "I didn't think it'd be strictly necessary but… This Wrathful State is a real handful and its light-speed Ki growth is something else."
"You'd have been shit out of luck, pal." A pale-faced young woman with curly brown hair showed her tongue before running it over Chayote's sweaty cheek. "Everyone's busy with the whole world-conversion business to pitch in and fight your battles."
"You're number One-Nine, aren't you? You look different from my blueprints." Future Gohan sighed easier, seeking to extract as much information as possible even at this time.
"I feel different too!" the sassy teen Android cackled. "When that dumbass 19 kicked the bucket, my body seemed to call out to his spare parts and absorb them somehow. Maybe Saiyans aren't the only ones capable of transformation? I guess you can call me a Super Android now."
"I see… 21 must not be aware that you've survived. That's interesting. Why would you be hiding from her?" Future Gohan turned his head in curiosity. "Is this a form of rebellion or something?"
"Why would I tell you anything?" One-Nine dug her pointy heels into the back of Chayote's knees, reducing the Wrathful Saiyan to a kneeling position while One-Nine found leverage to reach for her eyelid with her index finger and pull it down while she grimaced at Gohan. "I don't know what your deal is, so for all I know you can tattle on me to Android 21."
"You're operating under a false pretense that I care what happens to this version of 21 or this timeline." Future Gohan shook his head. "The moment I find out that you've betrayed 21, I'll be rushing back to my timeline to obliterate her for her betrayal and for being a threat to 21. That much is true. However, as thanks for your cooperation, I'll leave you to your business in this timeline."
"S… So… That's why you're here…" a tormented voice of Trunks made Gohan turn with his surprised expression. Shaking in pain and wear, Trunks rose on one knee, clutching his searing wounds and doing his best to cover up that which was bleeding and that which was sparking alike. "You don't care about ensuring 21's domination in all timelines, you're just worried that I might pull something that'll hurt the one in your timeline so you're here to stop me."
"Of course, you dimwit." Future Gohan tapped his head arrogantly. "You've had the right idea in the beginning, didn't you? This useless old timeline doesn't matter. The people here are like glass figurines. Sure, they look the same as in our timeline, but they're not them. Nothing at all will change if you smash one."
"You're wrong!" Trunks exclaimed, rising on his feet and drawing his sword. He seemed to lack the strength to resist meaningfully, but he raised and pointed his sword toward Gohan, regardless. "These people here, they are alive, just like the people back in our timeline. They feel pain, love, joy, and loss all the same. Their lives, their pain, and their feelings, they matter!"
Trunks charged onward, unable to even ascend to Super Saiyan, rushing in a hopeless vanguard, but Future Gohan soon put an end to it with a sharp and stiff kick in between where Trunks' throat ended and where his chest began. The hunter from the future raced across in pursuit of his opponent and punched Trunks in the gut, turning around with a roundhouse kick that fell Trunks down with an awkward angle to his neck. The unconscious Saiyan from the future laid sprawled out with whited-out eyes and a drool.
"Eh! This is amazing!" One-Nine tightened her clutch that kept Chayote helpless in her embrace. Somehow, the brat's limbs wrapped longer and longer, reaching more and more of Chayote's body. It took the Saiyan a while to realize that her bulk was growing smaller as the starving for power Android gorged and higher and higher rates of Chayote's energy. "It's like a never-ending feast, this Wrathful Form! If I pace myself, I could take her power forever and become almighty!"
"I see… So, you've gone mad with power." Future Gohan chuckled, clutching his cyber-arm while it acted up and bent out of shape while spilling sparks from the joints. "Who knows how much Ki you drained back in the future timeline. Lucky for 21, we've eliminated or converted all the fighters worth a damn, so after the Zenkai boost from this wild battle, you won't last against me."
"Be careful," One-Nine taunted Gohan. "You can't trace me, remember? I snuck up on this bottomless feeding pit just fine."
"Don't worry, I've got my ways of tracking you lot as 21's right hand." Future Gohan saluted the deceitful warrior before pulling his arm out and taking it apart with a strong yank. Grabbing hold of a single battery-like device, the warrior from the future became enveloped with an energy field that made the image of his presence seem unstable, warping and wrapping it out of shape. "A piece of advice, the Wrathful Form nearly did me in and pushed me to the edge. Don't fool around, suck Chayote dry and break her so that she can't move."
"Shut up, you're not the boss of me!" Chayote felt freedom around her numb right arm as her sneaky Super Android enemy thought it wise to flip Future Gohan the bird before he left this timeline to eliminate an immediate threat to Android 21 in Future One-Nine.
"Suit yourself," Future Gohan shrugged as the energy field enveloped him whole and once it dispersed in a wild lightning storm, only a cloud of dust remained where he once stood.
