"Spin in a semicircle while firing Ki Waves from both hands! This move is excellent against nearby opponents and relentless pursers."
— Dragon Ball Xenoverse 2 Skill description
Double Masenko (ダブル魔閃光) is a two-handed version of the Masenko used by Gohan.
Gohan puts both of his hands out at his left and right sides, and he then fires a Masenko energy wave out of each hand in opposite directions, inflicting a huge amount of damage.
Gohan uses this attack during the battle against Garlic Jr. and his remaining henchmen, Spice and Vinegar. After Krillin is beaten and kicked over the edge of Kami's Lookout by a transformed Vinegar, Gohan attempts to rescue his friend, but is soon interrupted by Spice and Vinegar. However, after witnessing Krillin about to die, Gohan explodes with rage and fires the Double Masenko against Spice and Vinegar, killing them both at the same time. Gohan then rescues Krillin and carries him up back to the Lookout to help Piccolo continue the fight against Garlic Jr.
