4 years after the death of Kid Buu, Goku just finished his morning excercise, when he heard something in the bush. He wanted to see what it is, so he disappeared and appeared behind the bush, but he saw nothing. Surprised, he tried to sense any energy around him, but he could only sense trees. He gave up from trying to figure out what it is, so he returned to the field and started to train.
Suddenly, he saw a yellow Ki ball coming at him at great speed. He yelled "Wha-!".
Choice 1: Be surprised and let the blast hit you.
Choice 2: Get serious and deflect the blast.
