Dragon Ball Ep 20 - 18:40 - Yamcha has become so proficient in the Wolf Fang Fist that he can easily outfight an actual wolfman at his own game. In other words, he outwolfed a wolf, which I find to be a very good indication of how advanced his technique is.

Dragon Ball Ep 71 - 4:30 and 10:28 - Yamcha vs See-Through the Invisible Man. Initially, See-Through's invisibility puts Yamcha at a disadvantage as he is unable to see any incoming attack and can't counter at all. Soon enough Yamcha takes the advantage when he figures out how to track the Invisible Man through nothing but sound alone, easily dodging and countering every attack See-Through throws out, until Uranai Baba starts singing too loudly for Yamcha to listen, putting him back at the disadvantage. Eventually See-Through is covered in blood from Master Roshi's nosebleed, making him visible, at which point Yamcha is able to effortlessly dominate him in a matter of seconds.
Dragon Ball Ep 72 - 9:40 - Despite being hopelessly outclassed by Bandages the Mummy's power and speed, Yamcha was skilled enough to evade his attacks for a prolonged period of time and put up a good fight.
Dragon Ball Ep 6 - 20:18 - Yamcha, realizing he cannot defeat Goku, concocts a plan to allow the boy and his friends to collect all seven dragon balls, and then steal them for himself once they've done all the dirty work. Throughout the remainder of this arc Yamcha pursues Goku and the gang in secret, subtly aiding them in their mission all the while remaining unseen like some evil mastermind.
Dragon Ball Ep 11 - 19:08 and 20:10 - With the gang imprisoned and Emperor Pilaf about to summon Shenron and take over the world, Yamcha, not Bulma or Goku, is the one who takes charge and thinks of what to do. It's his plans that end up saving the world.
Dragon Ball Ep 13 - 12:03 - With Oozaru Goku out of control, Yamcha is once again the one leading the group and calling all the shots, eventually severing Goku's tail and once again saving the day.
Dragon Ball Ep 22 - 19:10 - Yamcha deduces that Jackie Chun is really Master Roshi in disguise. Master Shen is the only other character in the series to figure this out, but he was Roshi's lifelong partner and rival for hundreds of years. By comparison, Yamcha barely knew Roshi, but was able to figure it out based off his fighting moves, his personality, his laugh, and his reaction whenever Master Roshi was mentioned.
Dragon Ball Ep 70 - 14:10 - In a matter of seconds, Yamcha formulates a plan that allows Upa and Puar, two of the weakest characters in the series, to defeat Dracula Man, who moments ago showed himself powerful enough to utterly humiliate Krillin. By taking advantage of stereotypical vampire weaknesses like garlic and crosses, Upa is able to scare Dracula Man off, while Puar uses his shapeshifting to keep the vampire from biting them. Once Dracula Man tries to fly away, Puar turns into a giant glove and quickly smacks him into the water, winning the match by ring-out.
Dragon Ball 72 - 13:27 - Despite being horribly outclassed by Bandages the Mummy's brute power, Yamcha is still able to outsmart him by feigning defeat, and then leg sweeping him off the bridge. Yamcha would have won the match right then and there had it not been for the mummy's wrappings forming a lasso to save him.
(FILLER) Dragon Ball Ep 13 - 5:25 - Yamcha conquers his crippling fear of woman in order to save his friends. As silly as it sounds, Yamcha's phobia was actually so severe that he would instantly pass out whenever he saw a woman, so being able to pick Bulma up in his arms and escape the area goes to show his determination.
Dragon Ball Ep 72 - 16:02 through 17:50 - Yamcha endures a prolonged beatdown from Bandage's the Mummy, a man with the strength to shake Baba's entire castle just by accidentally kicking the wall, which culminates in Bandages nearly breaking Yamcha's back over his head, yet all throughout Yamcha refuses to forfeit the match, or even lose consciousness for that matter.
