Safety (DBZ Fanfic)

The Beginning

(Grercher's POV) Wow, this Earth place is quite far, but it's what I have to do to retrieve Prince Vegeta and Kakarot. They must see that I mean buisness, I haven't been training since I was 5 just to fail.
Meanwhile on Earth.
Dialogue
"Vegeta, can you stoo being so serious, I can feel that energy too, but it doesn't seem too powerful." Exclaimed Goku.
"Yes, but...what if they are...hmm...hiding their full power." Suggested Vegeta.
"Well then it's a better fight." Said Goku with enthusiasm.
*Vegeta starts looking more worried than before*
"Vegeta, ever since Bulla turned 16 you've been different. You seem more protective." Goku pointed out.
"It's hard having a teenage daughter Kakarot, I know we've come a long way since the tournament of power, shoot, we were able to power up to Beerus' strength, but what if there's stronger people out there..."
"Vegeta, the only person stronger than Beerus is Whis, and no one will be stronger than him, unless they were training with someone like Zen-oh or Whis their whole life." Goku explained.
"I suppose I can loosen up a bit. Plus the person can't read our energy, we're gods now, so he's probably just a traveling alien." Vegeta realized.
Back with Gretcher
Alright there's Earth, time to retrieve them.
Grercher's ship lands where Vegeta and Goku are.
"Look Vegeta they're here!" Said Goku with excitement.
*Vegeta looks worried*
"Dad, uncle Kakarot, who is that?!" Yelled out Bulla.
*Vegeta's expression grows more worried*
Gretcher walks out of the ship.
"Kakarot, and Vegeta, it's great to meet you two both in person."
"Who are you, and how did you find us?!" Asked Vegeta with a serious look on his face.
"Oh, of course, I'm Gretcher, a surviving Saiyan from universe 6. I'm 17 and I have been training with Angel of universe 6 and was able to defeat Champa, the god of destruction."
"What really?! Wow!" Said Goku with excitement.
"So...you're a god?" Asked Vegeta.
"Yes, the God of Creation, but, the universe is going to shreds, so I've asked Zen-oh to transfer me to universe 7 and I've found you two."
"Ok, why did you wanna find them?" Asked Bulla.
"Well becau...wait, who are you?" Asked Gretcher.
"I'm Vegeta's daugher. Now answer my question." Demanded Bulla.
"Well...because they are the strongest in the universe, they might not be stronger than me, but they are definitely older and more experienced."
"Well, how old are you?" Asked Vegeta.
"I'm 17, I started training with Vados when I was 5." Answered Gretcher.
"Well I have one request Gretcher, I wanna fight you." Said Goku.
"Really, well, you may be more experienced Kakarot, but I can tell by you reading all your hidden power, I am still stronger." Said Gretcher.
"Come on, it'll be fun." Said Goku.
"Yeah, come on Gretcher, I wanna see a good fight." Said Bulla.
*Gretcher looks at Bulla and feels different*
"Alright." Gretcher says still looking at Bulla.
