Goku and Steve were training with Steve teaching Goku how to use the Shield to more efficient moves as Goku threw the shield to a droid and kicking it back to it causing it to be destroyed and hitting another.

Steve - Not bad form it took me at least a few days just to learn that move but you did in no time your a true prodigy.

Goku - Thanks but most of this was because I watched you guys train in the night.

Steve smiled and he grabbed the shield and threw it to the wall as it bounced away and started going in different with Goku closing his eyes trying to predict where the shield could come from.

Steve moved his head to the left with the shield coming straight to Goku but it was caught.

Steve - Impressive looks like I got nothing to teach you.

Goku - There's always something new to learn.

Wanda soon came in as Steve smiled and left and Goku and Wanda started their training with both of them asking if they can not interrupt them since it needed so much focus.

Natasha - Both really are bad at keeping their relationship a secret you know?

Steve nodded but he felt proud of Goku for being so happy and feeling so at peace something he hasn't for a long time since the war.

Vision - Captain Rogers.

Steve - Vision.

Vision - I would like to inform you that we have found information conforming the intel of Rumlow.

Before they could go somewhere a Bifrost portal appeared and they saw Thor running inside the compound and greeting the others like if he was in a hurry and quickly knocked on the training room well more like banging.

Goku opened the door and looked quite irritated but didn't get a chance to speak as Thor grabbed both him and Wanda and sat them down in the couch. 

Thor - My friends I have some swell news you know after everything that happened I wanted to invite Young Goku and Wanda to join me in a very important mission and that is what the humans call....."Show and Tell!"

Goku had a small excitement but it was gone when he realized Thor just wanted him and Wanda to go with him to talk to children.

Goku - Thor let me get this straight. You interrupted my important training so I can control my power even better just so you can speak in front of a classroom full of children?

Thor - Isn't exciting! Children wanted to see me!

Goku - Is this on  another planet?

Thor - Yes it's called Alabama.

Wanda sigh but laughed as she can tell Goku was really irritated since he loved his training but it was Thor who basically was like his Uncle or even more like an older brother who still acts like a child from time to time.

Goku - Okay first tell me one thing...Why us? 

Thor - Everybody knows Steve and Stark nobody cares about them. 

Tony - Hey screw you too Pointbreak!

Steve rolled his eyes and went to speak with Vision about his mission and Goku just nodded and said he will go just he needed to change. 

Goku - Also Thor have you ever heard of anything of Saiyans?

Thor - Yes. The Saiyans were a warrior race who would destroy the inhabitants of planets and sell the planet to whoever wanted to buy the planet. They tried once with Asgard but it didn't work however over 50,000 years ago my grandfather had met a pure hearted Saiyan called Yamoshi and he became the first ever Super Saiyan and what the legends called "Super Saiyan God"

Goku - What does a Super Saiyan look like?

Thor - I'm not sure my grandfather said Yamoshi had a golden aura but then it changed to a fiery red aura.

Everyone smacked themselves in the face mostly in the stupidity of Thor for not realizing something that was right in front of him.

Goku - So you mean like this? 

Goku powered up and his hair spiked up and he transform into the same form he used when he fought the Hulk.

Thor - Yes he said it was golden then a red fire.

Goku - Are you not seeing what I am trying to show you?

Thor was visibly confused since he didn't really show much focus on what he was trying to tell him.

Goku - You gotta be fucking kidding. (sigh) Fine I'll show you the other.

He took a breath and his eye changed from teal green to red and his hair went back to his normal state but it went red.

Thor - Oh my goodness Young one your the Super Saiyan and the Super Saiyan God! 

Goku sighed but smiled believing he was either faking it or he really was that dense.

Goku - At least I know now so how about we don't leave those kids waiting.

They took the Quinjet and during the ride Goku learned many things from Thor's adventures exploring the Universe. But one got his attention, it was a planet that he called Yardrat. The Yardratians have special techniques but it all comes from one technique called Spirit Control.

Goku - I would like to go to this Yardrat one day maybe you can take me someday?

Thor - Of course.

After 2 hours of flying they made it to Alabama and went to an elementary school that was more populated. Thor walked out the Quinjet and Goku and Wanda walked behind him hoping it doesn't turn into a disaster.

10 minutes later

Goku was in the back of the class with his hands on his face regretting showing up. 

Thor - The hallways were dripping with blood and gore. Then I removed the villain's head from his body. His guts spilling everywhere haha and of course I ate his eyeball so that he can never find his way back to the halls of Valhala again.

Goku and Wanda were shocked the teacher agreed to this. She was just looking at Thor with lustful eyes.

Goku - Okay kids it seems Thor has told you his story and now It's time for recess.

The kids cheered and said bye to Thor, Goku and Wanda. After they left Goku pulled tightly on Thor's arm.

Thor - Ow what's the big tight grip there. young one?

Goku - You are never telling human kids your story again. Got it? No buts, no ifs, and no excuses. Tell any other kid in the universe but not human kids got it?

Thor nodded sadly he wouldn't be able to tell anymore stories.

Goku - We don't want kids making swords and fighting each other for a piece of candy in the future. You have stories tell them to me and the others. We love your stories Thor.

Thor - But it was something new...please.

Wanda pulled Thor's ear and scolded him with him finally understanding and holding his ear.

Goku - Now go back to space and look for the Infinity Stones you were talking about!

Thor - Shit. That's right I was doing that. Hahaha well good luck and farewell.

He smiled and summoned the Bifrost with both Goku and Wanda inside the Quinjet in silence.

Goku - Wanda?

Wanda - Yes.

Goku - I want a kid and I wanna marry you now.

Wanda - w-w-what are y-you saying?

Goku - The way you scolded Thor. The look in your eyes made me want you so badly right now. Come here.

Gomu pulled Wanda for a kiss as he clicked the autopilot and both were headed back to the Avengers compound.

2 hours later

Goku - "phew" We're back!

Steve - Good because we're leaving tomorrow.

Goku - Where?

Steve - Lagos. We found Rumlow.
