(The Central Battle Zone)
A series of explosions racked the buildings of the city outskirts making up the exterior section of the final battle zone. Smoke and debris flying up into the air and following a straight line, like a flameless napalm strike had just been mounted against the town, the hotel at the edge of the river suddenly collapsed in on itself when Gokuha came blasting out of its walls with Trunks's head in his grip.
Rocketing up into the air, the green-skinned alien let out a cry of war as he then took the hapless demi-Saiyan and dove towards a nearby bridge, plowing his opponent's face straight into its road. Destroying the causeway, the pair then disappeared underneath the water in a series of depth-charge like splashes, which the alien continued to drag his opponent through for several seconds. Moments later, the lavender haired warrior managed to free himself from the titan's grip and shot out of the river, leaping across the rooftops of the city and beginning to dive back down to ground level feet first.
While in the middle of his descent however, the building in front of Trunks shuddered violently, before the hulking form of Gokuha came bursting out of its wall and clothes lined the unsuspecting Saiyan in the neck, sending him through several more buildings. When the lavender haired warrior exploded out the side of the fifth one, Gokuha seemingly teleported above him and kicked the man towards the ground, sending him bouncing along the main street. Trunks's form eventually rolled to a painful stop, leaving the man splayed out on his front and groaning in pain.
Landing several feet behind the boy, the smirking alien approached him, drawing his sword and pointing its tip at the Z-fighter's back.
"You're beaten. Surrender!" The man was confident at his victory.
Waiting for a response, Gokuha watched as his opponent started to push himself up, struggling to get onto his hands and knees. His smile fading, the alien then spat and, taking his sword up into a two-handed grip, gritted his teeth and roared, "FINE!" He then thrust straight down at the hapless fighter, aiming to impale him.
Sensing the attack, Trunks's eyes widened and he powered up, his golden aura exploding around him when he jumped to Super Saiyan almost instantaneously. The second he did so, he spun around and parried the incoming blade with his arm, locking the pair in a heated grappling match. Caught completely by surprise, Gokuha then began trying to force his weapon through his foe, while his opponent bit and held his ground with all the strength he could muster.
Their energy blasting off of them in waves, Trunks snarled, "Never underestimate a Super Saiyan, punk!" And with that, the blade pressing against his forearm shattered, sending the tip of it spiraling into a wall.
Stunned, Gokuha was just about to pull away when, in the blink of an eye, the golden haired warrior in front of him plowed his fist straight through his chest like a lance.
His fist exploding out the other end, Trunks held his position while his opponent spewed up blood and hunched over the smaller warrior's shoulder in shock. Body quivering for several moments with a few choking sounds escaping the swordsman's gaping mouth, the time traveling Saiyan then ripped his arm out of the warrior's chest and allowed him to tip over. The alien's body crashed to the ground with a dull thud, where he lay dead.
As Trunks stood there, catching his breath and looking down at his defeated opponent, wondering where in the world he'd come from, the demi-Saiyan then sensed a second presence appear. Gasping at the enormous flux of ki, the boy spun around, only to have his vision blinded by the blue tail end of a coat, before he was unceremoniously kicked in the face.
The force of the blow was so immense, it not only caused a shockwave that split the ground, it also knocked Trunks out in an instant, his body hitting the ground hard.
OOO
(Meanwhile – Capsule Corp)
Bolting upright from his bed, Vegeta gave a gasp of shock when he sensed something amiss in the air.
Having subconsciously been keeping an eye on the Intergalactic Tournament taking place many miles away with his senses, the man was able to monitor the progress of all the competition's major players; namely the Z-fighters. Things had been going well to this point, until he felt his son's ki skyrocket and plummet in the span of a few seconds, before being completely overshadowed by an energy level that was not only enormous, but incredibly foul.
"T-Trunks?"
That was no ordinary energy level. That was something else.
Something dangerous.
Gritting his teeth, the man turned towards his son's sword, which he could see propped up against the wall.
"Something's wrong."
OOO
While dodging the rain of car-sized boulders being thrown at him by his unusually powerful foe, Gohan attempted to put some distance between him and his adversary. However, just as he was preparing to up the ante a little and give his enemy a taste of his real power, a flash of ki suddenly rushed through his head in the direction of another battle zone, stopping the demi-Saiyan for but a moment.
It was unreal. The energy level was so massive and so potent that it was impossible for the young warrior to miss.
Gasping, Gohan's eyes snapped over his shoulder, "Who's there?" Reaching out with his senses, he noticed seconds later that Trunks' energy level had dropped considerably, telling the boy that his friend had been taken out.
Clenching his fists, the fighter quickly glanced back at Bujin, whom he saw float down from above atop an enormous rock, surrounded by a malicious orange aura. The little alien giggled when he too picked up the issue plaguing his young opponent.
After several seconds of consideration of both his foe and the foreign ki signature over the horizon, Gohan made the critical decision to dispense of this fight and to go help his friends.
Levitating off of the ground, the spiky haired warrior then turned in midair and took off towards the other battle zones at full speed. Sensing his opponent flying after him, Gohan made sure to keep one eye on him and the other eye straight ahead, as he then began tracking down whatever the hell had taken out Trunks.
"Don't worry guys! I'm coming!"
OOO
(Otherworld)
"Earth is in grave danger!" King Kai spoke, glancing back at Goku to see that he, Bubbles and Gregory had also gotten to their feet. After the events they'd just witnessed, it was impossible for any of them to remain seated.
The spiky haired Saiyan stepped forward anxiously, "From what?"
"You mean who. Bojack," the blue-skinned overseer of the Northern Quadrant replied cryptically.
Gulping at the nervous glance the man gave him, Goku pressed on, "B-Bojack? Who's that?"
"A dark demon of the worst sort; psychotic, unstable… filled with malice and rage. Long ago, he tried to destroy every galaxy within the Dormideous Sector and attempted to conquer the core star systems between the four quadrants," King Kai informed, a bead of sweat running down the side of his head as he filled Goku in on what he didn't know about this new enemy. "He and his gang rampaged across the galaxy, wrecking everything in their path."
"Sounds like King Piccolo," Goku remarked, thinking back to his encounter with the evil Namekian all those years ago.
King Kai nodded, "Yes, but far more powerful… even stronger than Cell when you first fought him." The trainer then looked gravely over the horizon of Snake Way and watched as the sky seemingly darkened as he slowly recounted his story. "He has an insatiable appetite for genocide, even going so far as to wipe out the entire population of his home planet. Now, just like the Saiyans, he and his group are some of the only remaining Hera-seijin's left in the universe. Over ten thousand years ago, we took it upon ourselves to stop him. All four of us kais worked together and sealed Bojack within a star at the edge of the Northern Quadrant."
"He's trapped in a star?" Goku asked in amazement.
This question had King Kai pace around, before looking back at the Saiyan uneasily, "Not anymore. You set him free when you destroyed my planet in your battle against Cell. The four point seal was broken and allowed Bojack and his gang to escape. Now he's returned to finish what he started… to conquer the universe." The man's glasses flashed as he then looked up once again, this time with fear evident on his face, "And it looks like his first target is planet earth."
In spite of this grave news, Goku was unshaken. In fact, a smile broke out on his face as he regarded his trainer's information with confidence, "Then he's already defeated. My son will stop him."
