A few minutes later, introductions were made

Gizmo was flying alongside Goku and Vegeta, he was nervous yet excited for the journey ahead. 
“You must be hungry huh?’ Goku asked  the teen which Gizmo replied with a nod “yes, I’m pretty hungry.” he said, Goku smiled, Vegeta was neutral and Gizmo was excited, he finally met some people who were somewhat kind to him.

As Goku, Vegeta and Gizmo landed in front of an all you can eat buffet. The three saiyans walked into the restaurant and began to chow down, Goku went crazy eating some chicken and rice. Vegeta had some calamari as an octopus shot ink into  the prince’s eye mid bite; to which Goku laughed at. Gizmo ate about 5 bowls worth of ramen and started his 6th. 

Hours pass, training begins 

As the trio land into the field of capsule corp. Gizmo spoke up to ask  “How are you two so strong? And can you help me reach your level of strength?” 

Goku gave Vegeta a silent look of approval, Vegeta crossed his arms and sighed “I agree with kakarot. We will put you through our training.” Gizmo smiled “let’s get started!” 

Power level unleashed, someone’s attention had been caught

Gizmo and Vegeta stood next to each other “Alright Gizmo, I’ll be teaching the Galick Gun to you.” he said as he started powering up, he cupped one hand in the other by the side of his head as purple energy surrounded him, he grunted slightly as he thrusted his hands outward “GALICK GUN!!!!!!” He yelled a purple beam was launched into the sky leaving the atmosphere and dissipating in outer space.

Gizmo looked amazed as he started doing the movements Vegeta did with the prince correcting the mistakes the teen made. Gizmo started charging his ki which started forming around him as he charged the attack,  and fired the blast into the air as the ground cracked and broke. The blast was at least 2 times stronger than Vegeta’s blast. The prince looked amazed and smirked with pride “another pupil well powerful.” Goku was excited  as he ran over “Ha ha!” he exclaimed, “I gotta teach you the kamehameha!” Gizmo smiled “let’s get started!”

Goku cupped one hand over the other at the side of his hip “Ka…..” he said as a blue orb appeared in his hands  “Me…..Ha…...Me…..” the blue orb grew as he thrusted his hand forward “Ha!!!!!!!” he yelled as the much larger beam flew into the sky and much like the galick gun disappeared into the vacuum of space.  It was Gizmo’s turn to fire the blast “Ka…..” Gizmo did the movements perfectly “Me…...Ha….Me…..” Gizmo thrusted his hands forward like Goku “HA!” as he unleashed the blast he accidently went super saiyan. The blast moved clouds and lit up the city.

“Oh hoho!” cried the angelic voice of Whis  “another saiyan? Lord Beerus will have some reaction!”
