Although he was born after Khaosai, he was still considered by the Thai as the older brother because of their ancient belief regarding twins.
Their parents eventually took them to meet their first Muay Thai trainers, Prakan Vornsiri and Mana Lhawpradit.
Khaokor Galaxy made his professional boxing début in 1985, winning his first seven fights before capturing the Thailand bantamweight title in July 1986.
After Khaokor and Khaosai won their titles, Tam Pai Doo, a variety TV show on Channel 9, organized an exhibition bout that pitted the twins against each other, the contest was produced at Rajadamnern Stadium, Bangkok.
The defeat to Espinosa was unexpected, but Khaokor was caught with a left hook, and about 20 seconds later just collapsed out of thin air.
At that time, this matter was a huge sensation in society, it was called Rok-wubb (โรควูบ, "fainting syndrome").
After retirement, Khaokor revealed that it was because he had lost a lot of weight at that time, coupled with stress, that caused it to happen.
Khaokor was sent to the ICU for 21 days while, Khaosai only suffered minor injuries and would later be back to professional boxing.
Khaokor had many businesses such as a snooker club, selling car roof accessories, and a restaurant in Bangkok.
Currently, Khaokor married Tak Jirapwan (Thai: แต๊ก จีรวรรณ) and have two sons, with four years age difference.
