Lightning Flash Surprise Attack

Thunder Shock Surprise (萬國驚天掌; lit. "Myriad Kingdom Surprising Heaven Palm") is one of Master Roshi/Jackie Chun's most powerful attacks. The user shoots a lightning blast towards the target using both hands, and traps the opponent within an electric field. According to Yamcha in the English dub, this technique turns all the energy in the user's body into 20,000 volts of electricity. This attack is named after a 1967 Japanese variety show "Bankoku Bikkuri Show".
