I think it was the fifth magna ep where he rears his head in the original dragonball. Starting off as an enemy he attacked the dragonball gang only to get his butt kicked by Goku... (well duh!) Yamcha then befriended him... strange how Goku has that effect on people... But he followed them on their quest for the dragonballs to make his wish to... (yus we all know this part...) get over his fear of woman...
As the series progresses his fear somewhat becomes non existent and him and Bulma hook up... They date through to the mid dbz. Yamcha also trained under Roshi when he was a bit older and later in the db series where he learns the Kame Hame Ha wav and perfects his Rouge Whowoken attack and it’s upgraded to Shin Rouge Whowoken (you actually see this used on King Ki’s against the Ginyu force)...Yamcha has a brief career in Baseball where he is in it only for the money so he can pay his rent. Then along come the saiyans and after showing a great fight. He gets killed when one of the saiyan's sabimen cheeps him. Now I was highly annoyed at this... well Yamcha receives training on King Ki’s with Tien, Chaoitsu and Piccolo... They’re wished back and yadda yadda...
Bulma hooks up with Vegeta leaving me wondering who is this someone else that Yamcha finds that Trunks mentioned... But as dbz carries on Yamcha is thrown in to the background along with the non saiyan and namek types... He is described as one of the “weaker” characters but still one of the world’s strongest HUMAN fighters... Even though this happens he will still be my favorite character from the Dragonball series...
The name of Yamcha gives you the desire to understand and help others with their problems but, at the same time, you can become too involved in their problems and, as a result, worry too much. This name creates a pleasant, easy-going, yet responsible nature. It gives you a natural ability to express affection to those close to you, without feelings of embarrassment. You tend to avoid issues, however, and put off until tomorrow the things which should be done today. Accordingly, you would find difficulty in achieving success in positions requiring aggressiveness and drive. Also, you prefer to avoid strenuous work of a manual nature. Your natural inclination is to pursue a line of work where you have contact with people, where you carry some responsibility, and where you are engaged in mental rather than physical activity. You are diplomatic in your handling of people and always give others the benefit of the doubt. You appreciate good music and art. The health weaknesses created by this name affect the fluid functions.
