"You know they are here, Kakkarot! Just because we can't see them doesn't mean we can't feel their Ki. After all, you wouldn't have been able to Instant Transmission here if there were no Ki signitures"
Goku, seeing the wisdom in Vegeta's logic, decided to follow the Prince's instructions for once, and reached out with his senses to detect any nearby life forms. Although his eyes saw nothing, he did feel the distinctive energy of life forms, powerful life forms at that.
"Vegeta! Have you felt their energy? This is the strongest group of people we've come across yet. Maybe they can help us get home!"
"Don't get your hopes up, Kakkarot. They have yet to even show their faces, the cowards."
And with that statement, the air shimmered in front of the two Saiyans, and suddenly a strange looking alien appeared. He appeared to wear some type of silken robes, and was crowned in a strange headdress. He observed the two for quite some time annoying Vegeta to no end with his inaction, before finally speaking?
"Have you come to receive the gift of the Eldar?"
"Huh?" Goku asked.
"Have you come to receive the gift of the Eldar?"
"Baka!" shouted Vegeta. "We don't care for your ramblings, just tell us, are you able to sense energy? How far do your senses extend?"
"Yeah!" continued Goku. "You see, we're kinda lost. I was using a technique called Instant Transmission, and lost my concentration, and ended up here. Vegeta kinda got dragged along, so now we're both lost. We've tried to sense our way home, but no matter where we go its useless. Then I sensed your energy, and since you were the most powerful thing I've sensed so far, I was hoping you could help us! Can you?"
However, Goku's speech was lost upon the Eldar Farseer. As soon as Vegeta's insult was spoken, the proud xeno leapt to the chance to defend his people. "You dare, you dare call me an 'idiot.' I am a Farseer of the Eldar. My race had a galaxy wide empire when your race was still composed of single celled organisms and floated around in puddles of goo."
Vegeta, having the same pride in his people as the Eldar, could not let the Farseer's retaliatory insults go unanswered. "Eldar, eh? Your race appears to be made of just a bunch of low power idiots who aren't saying more that a simple sentence. I am a Saiyan, Farseer. My race is a race of warriors, the finest warriors in the galaxy. I am the Prince of all Saiyans, you are nothing compared to me."
"A race of warriors!" responded the Farseer. "We are the Eldar! Our history is littered with more battles then your small mind can comprehend. I am one of the most powerful Psykers in the galaxy, I am capable of crushing entire worlds with only my mind!"
"Oh, wow, you can destroy a planet. I could do that when I was seven years old! I used to be a purger! I would travel from world to world, killing its inhabitants, sometimes regularly blowing up planets for raw materials. You are nothing."
Goku, stepping in before the Farseer could reply once more, and before Vegeta could resume his old job of purging, this time going after the Eldar for insulting his race, quickly shoved a hand over Vegeta's mouth and used his other to loop the Prince's arms behind his back, leaving him immobile.
"Hehe, sorry about Vegeta," apologized Goku. "He's a little more proud of our race then I am, he doesn't take to insults well. We'll just leave before we offend you anymore. Bye!"
And so Goku and Vegeta left once again, leaving a baffled Farseer, who was wondering where his opponent went, and an extremely angry Vegeta, who was shouting muffled cries of 'Kakkarot you fool! He deserves to die for his insults! Let go of me! Kakkarot!'
