After the death of Demon King Piccolo, the planet of Terra experienced a golden era of enlightenment and innovation that would last over the span of Six Years, with the invention of the Gravity Chamber happening four years into this new Era. Many of the team had their own part to play, with Son Goku eventually marrying childhood crush Chi Chi, and Krillin falling in with Old Man Roshi. The Z-Warriors were a fully-fledged team with the addition of Piccolo Jr and despite the past would come together for training within the Gravity Chamber.
On this day, however, Hakurei sat within the first floor of Capsule Corporation Headquarters behind that of Bulma, his fiancé', as she revealed to him the small robot which she was currently fine-tuning when Son Goku arrived holding an unexpected passenger. The first to greet Goku would be Lucien of course, her fur tail twitching slightly with anticipation as she watched the young kid that Goku had along with him. "Ahh, Son Goku, how are you and Chi Chi doing? And who is that?"
"Oh, this is my son. I named him Gohan after my grandpa. I wanted to bring him to meet all my friends and of course my Mentor so I brought him here!" Goku let the little boy settle to the ground, wearing a blue T-Shirt that read 'Mama's Boy' and a pair of jeans. Set upon his cap was none other than the Four-Star Dragonball. The child had a respectable power of nine-thousand and inherited a tail similar to his father's only of a lighter brown hue. Hakurei and Bulma left the workstation and walked towards Son Goku.
Hakurei smiled to Goku, happy that the Goku of this world at-least was a better man and father than his canon counterpart. Goku had been present in raising his son and even taught young Son Gohan the basis of martial arts. Hakurei's train of thoughts were interrupted when a loud 'beep' chimed from his smart watch, followed by an announcement from a smooth metallic voice. "Foreign Spatial Object has crashed fifty kilometers outside of West City. UMSC requests your intervention. Do you accept, Commander?"
"No, deny the request. The UMAF are more than capable enough to recover a downed Satellite or Spacecraft." Responded Hakurei, before turning back towards Goku with an uneasy grin which was returned with an inquisitive look from Goku. Hakurei motioned to Bulma, who produced a black box that, when opened revealed an identical pair to the one on the wrist of Lucien and himself. Hakurei spoke up as Goku examined the watch. "The latest production by Capsule Corp, and now standard issue to all members of the Z-Warriors."
He continued, "The Watch distributes and tracks all missions via the AI, Veda. The watch is also installed with a bevy of apps including communications, maps, compass, scientific calculator, and a music player. Krillin has already come by to receive his and Piccolo will be by later today. This one is for you." Goku reached down and picked up the sterling silver band with chrome and electrum-gold detailing. Goku placed the watch on his wrist, auto-adjusting to his wrist-size. A male with long, spiked black hair resembling Son Goku suddenly stepped forward.
"Kakarot, I've found you at last," the warrior spoke in a deep and raspy tone, "I see you've come to co-exist with these weaklings instead of destroying them as you should be." Son Goku cast an odd glare to the warrior dressed in battle armor then noticed the smoke rising from the city in the direction the man had come, then gritted his teeth. Despite having sensed the disparity between the two, Goku brought his son close with a quick grasp, he didn't want the child any closer to this alien who claimed brotherhood.
Another warrior with short black hair lightly smacked the back of Raditz' head and spoke to his fellow in a chastising voice. "This is no way to greet your long-lost brother! If you remember, Kakarot was sent from Planet Vegeta when he was a baby and probably has no memory of your parents, so shouldn't you prioritize informing him about your parents instead of being so cruel to him? I do apologize for my junior's inadequate introduction, I am Scallio and this is your brother Raditz. You are a member of the proud Saiyan race, or what's left of it..."
Goku looked baffled for a moment, however something clicked in his mind - something that his sensei had told him years ago now made sense. His hand wavered and returned to his side rather than protectively over his son Gohan. "Ah, so You're my brother from an alien mother! Wow, you don't look anything like me just like Rei-Sensei said. Well, why don't you two come on in? We can catch-up over a nice feast of delectable food, after all Bulma-Kun's mother makes just the best food after my own wife - after all."
Son Goku along with Hakurei and Lucian stepped into the building itself, followed by Raditz and Scallio. The lowborn brother Raditz marveled at the detail and technology inherit within the building which was not inferior in the slightest to the technology the Saiyans were making use of and in ways was perhaps even more advanced. They entered a room, where the feast had been prepared and the group arrayed themselves around the table and began to dig in to food.
