The Lost Brother
At this point Goku/Kakarot is 12 and Gohuken is 22 and Goku has just now started on his journey with Bulma. But as for Gohuken not much seems to happen until this very day of a sudden invasion of privacy if you will.
About 2 months into Nail being the new guard for Guru and after a long and strenuous 6 hour spar with Gohuken something odd happens.
"So lord Frieza wants us to look for someone on this desolate planet with such weak power levels" said one of the alien invaders."Well it's supposed to be some saiyan named Gohuken with a power level of about 13,500 12 years ago, and you know how strong saiyans get." "It's a good thing our emperor wiped out nearly the whole band of monkeys so that we wouldn't have to deal with them anymore." "I'm picking up 5 power levels. With all of them ranging somewhere between 3000-5000. Nothing to be afraid of". Said the leader of the band of 3. "What purpose do you 3 have on our planet?" One of the namekians spoke. The leader then replied. "We just want the one saiyan named Gohuken, and if you lead us to him now we won't hurt any of you guys. Hell, lord Frieza might even recruit a few of you" "Sorry but we're gonna have to decline your offer and ask you nicely to please leave our planet before things get really ugly." Well it's your loss then. Bapanna, Canelis it is time we have some fun." Then faster than the speed of light the 3 invaders came crashing into the namekian warriors and sent them all flying. But as if in unison the nameks then began charging up their ki to their max. "Well, well, well it looks like they've been holding out on us this whole time," "Yeah but not by much really, the strongest one's power level is about 8,500". "Okay guys we have to come up with a strategy to stall long enough for Master Gohuken and Nail to arrive." Nansen said telepathically. "Well since you're the leader of the group, you should be the one to make it up." Creok replied. "Well you could say I'm having a brain fart because I can't think of anything right now, so any suggestions?" "We could actually do one thing but I don't think that it will work". "As of this moment anything will work, so we're just gonna have to go for it." "Alright, well here's the plane …" "Break!" They all mentally shouted. "I think that they've got a plan, don't you Pinnappa?" "Yes I do Bapanna, and it's time for us to disrupt that plan right now." Then suddenly while the two were conversing a vast array of ki blasts then came tumbling at them at faster than light speeds. "Ha, too bad they all missed." "That's only what an idiot would think and now it's time for this plan to come full circle. Now, tornado whiplash"! As Pinnappa turned his head around he saw a giant culmination of the ki blasts fired forming a humongous tornado of extreme power and force." These guys make up for their power in their creativity. However it will be to no avail. Full power energy wave"! He screamed. It ended up destroying the 60ft tall tornado with but a single flash. "It was a good plan except for the fact that I was just too powerful for such a lower level technique". "It wasn't meant to hurt you jackass, but to warn the others of the trouble we're in." Creok replied. "Well then who is gonna save you now." "Them".
