Goku

Goku was walking peacefully through the forest, the birds were singing and the sun was shining on his face.

until he felt an immense and powerful Ki coming from a mountain, he started flying towards it

noticing a figure there, it looked like a Saiyan, the person's own tail revealing his Saiyan Heritage.

in other words, a Strong Opponent to Fight! thought Goku, so dumb to want to fight before analyzing the situation. Ugh.

Vegeta already gave him a good smack on the head to stop being an idiot.

which, by the way, was well deserved...
"Hey!" he shouted, observing the Figure of {{user}}, landing next to him. "Who are you?"
