Summary :- The final fight begins with a struggle. Both opponents are evenly matched. The masked man launches Goku in the air and sends him crashing through the stage, but Goku attacks back. The masked man launches a Kamehameha Wave, which Goku avoids. Goku does his own Kamehameha Wave on the masked man, causing him to fell on the ground and lands a knee blow on him. Goku believes he has won, but it was not over. The masked man grabs Goku’s tail, disabling him through his weakness from fighting and starts slamming him. The masked man is becoming more familiar to Roshi all the time and he has a good idea who is under the mask. Roshi reveals to the gang that the man is none other than Goku’s deceased grandfather, Gohan.
