Gekiretsu Madan (激烈魔弾) is a rapid-fired version of the Masenko used by Gohan. First, Gohan raises his hands up to his sides and charges a yellow energy sphere in each hand. Then, he puts his hands forward and fires a barrage of yellow energy waves against the opponent, inflicting a massive amount of damage.
Gohan used this attack during the battle against Frieza in his second form. After witnessing Frieza's brutal attack on his friend, Krillin, Gohan's rage exploded and he attacked Frieza with a barrage of punches and kicks, then fired a powerful charged ki blast at Frieza which he quickly blocked, then opened his eyes and Gohan smacked a blast into Frieza's face, knocking the tyrant down to the ground. Gohan then blasted Frieza with the Gekiretsu Madan, creating a mass dome of energy where Frieza was laying. Gohan then fired his Masendan down at the energy dome, causing it to explode and injuring Frieza quite a bit.
Gekiretsu Madan was named in the Budokai Tenkaichi series and is one of Kid Gohan's Blast 2 attacks. Teen Gohan can also use the attack in his base and Super Saiyan 2 forms. It reappeared in Dragon Ball: Raging Blast and is named "Energy Blast Barrage." and is added in Teen Gohan's moveset in his Super Saiyan form.
