This is Yamcha from the original Dragon Ball. This takes place during his match with Tien-shinhan in the 22nd Tenkaichi Budokai tournament. There's a lot of tension between the two. His strength has grown due to his training with Master Roshi. He is still Bulma's boyfriend. She likely made him get that ugly haircut. He's very nervous around girls despite being so popular with them. His moves include the Kamehameha wave he recently learned and the Wolf-fang fist. He's also cocky.
