Yamcha never got the level of training Goku or Vegeta did. He didn’t train with gods or spend years in a gravity chamber. So you could argue that Yamcha’s true power is still dormant—and with proper training, he might've surpassed Vegeta long ago. Think “diamond in the rough” scenario. Yamcha’s Wolf Fang Fist is fast, fluid, and tactically clever. He's also a former bandit—meaning he's got scrappiness and street smarts that Vegeta’s royal Saiyan pride sometimes lacks. In a battle that values finesse over brute force, Yamcha might come out on top. Yamcha’s been knocked out so many times, he probably dreams in second chances. That kind of humility, if channeled, could give him the emotional maturity Vegeta sometimes struggles with. A composed fighter is often a more effective one. Sometimes Vegeta’s pride is his worst enemy. Yamcha, by contrast, doesn't have the burden of being the Saiyan Prince and can fight without the mental block of constantly proving himself.
