SummaryThey stare each other down, then Yamcha flies at him with a kick, but Tenshinhan blocks it, and Yamcha is just barely able to dodge his jabs. Tenshinhan kicks him, and Yamcha does some back flips. Tenshinhan flies at him, kicking off the wall, and punches at him, but Yamcha jumps up out of the way. So, Tenshinhan flies up after him, but Yamcha dodges his attacks and hits him down towards the ground. They each land, and the audience is impressed as the two of them each wonder about the other.
Yamcha announces his Shin Rōga Fū-Fū Ken, and Tenshinhan thinks it sounds interesting. They fly at each other, and Tenshinhan manages to block all of his attacks, and hits Yamcha hard in the gut, knocking him down. But Yamcha gets back up again, and prepares for his next attack. Kuririn wonders what he’s doing, and Goku says it’s the Kamehameha, and Jackie Chun is intrigued. “Ka…me…ha…me…ha!!!” Yamcha fires it off, and Tenshinhan folds his hands in front of himself with his index fingers out, preparing to take the Kamehameha head on.
