Kid Gohan

How Kid Gohan joined the Tourney
When Gohan is first introduced, he wears a child's outfit with his family name, 'Son', written on the front and the Four-Star Dragon Ball attached to his hat, the same Dragon Ball in which Goku believed that his grandpa's spirit resided. Before he transforms into Great Ape and mostly appears in the ending theme of the anime, Gohan wears a white tank top and his green pants and black shoes from his child attire.

After the battle on Namek, Gohan was brought to study at Chi Chi's home. Suddenly, a badger named Sticks arrives to offer a treasure hunting quest to the boy.

Gohan flies into the air side kicking two times.

Leave My Daddy Alone! (Down)

Super Masenko (Hyper Smash)
Gohan fires a larger and more powerful Masenko that inflicts greater damage than a normal Masenko.

Wild Rush Blaster (Final Smash)
Gohan kicks his opponent a few times, he then beats them up and kicks them to one side. He holds one hand with the other supporting it upward in a fashion similar to the Explosive Demon Wave and, as he shouts "I've had enough!", he forms an energy sphere with excess energy releasing off of it in the form of medium-sized energy rings. Finally, Gohan brings his hands forward and fires a powerful yellow energy wave with a large energy sphere at the end at the opponent, inflicting a high amount of damage.
