All we know about ox king's power, is that he was in the same class as grandpa gohan. Grandpa Gohan absolutely destroyed goku post Korin training. all yajirobe did on first appearance was defeat one of piccolo's kids. If we're using anime versions, then yamcha could do that with a broken leg.
If we're not using the anime version, I would like to change my answer to cyborg mercenary Tao
Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
it's been a while since I've watched dragon ball, but I think it was in his introduction. He recognized the power pole and told goku the story of how he and gohan trained under roshi

Did it not? After training with roshi, yamcha was strong enough to convince tien he was roshi's prize pupil. After training with king kai, gero thought he was goku based solely on how high his power level was. Goku just happened to have leveled up under Morin and the yardrats in the meantime
