First, Pikkon sways his arms around his body as he produces a blue flame-like aura. Then, he draws his hands out to his sides and closes them into fists as he crosses his arms on his chest. Finally, Pikkon draws his fists together in front of him and fires a huge storm of flames at the opponent, inflicting a massive amount of damage through a fiery explosion.
Pikkon uses this attack a few times during his match with Goku in the Other World Tournament. After being repeatedly blasted and injured, however, Goku eventually discovers the weakness of the Thunder Flash Attack: Pikkon cannot move while he is performing the technique. Using this to his advantage, Goku uses his Instant Transmission to teleport away from the Thunder Flash Attack and appears beside Pikkon to blast him out of the ring with a Super Kamehameha.
