Early Career
Before he was a UFC star, Stephen Thompson was unstoppable in kickboxing. He started training at a very young age because his father, Ray Thompson, owned a karate school. Stephen was naturally gifted and worked very hard.
He fought in 57 kickboxing matches and won every single one of them. That means his record was a perfect 57-0.
Because he was so good at kickboxing, he decided to try Mixed Martial Arts (MMA). He wanted to see if his karate style would work against wrestlers and boxers. He started fighting in smaller shows and kept winning.
His unique style made it hard for opponents to hit him. He would stand sideways and throw kicks that no one could see coming. This success led him straight to the biggest stage in the world, the UFC.
Professional Career
Stephen Thompson made his UFC debut in 2012, and he made a huge splash right away. He knocked out his opponent with a head kick in the very first round. This earned him the “Knockout of the Night” bonus.
Over the years, he fought the best fighters in the welterweight division. He even fought for the world title twice against Tyron Woodley. One of those fights ended in a draw, which is very rare.
In recent years, things have been tougher for Wonderboy. As he got older, he faced younger and stronger opponents. In 2024, he suffered a tough knockout loss to Joaquin Buckley.
Then, in July 2025, he lost a very close fight to Gabriel Bonfim by split decision. Even though he has had some losses lately, he is still respected by everyone for his skills and sportsmanship. He has never given up and always puts on a show for the fans.
