that would become Aerts' signature move. These wins gave Aerts the reputation as a top-level kickboxer and he was invited to take part in the K-1 Grand Prix '93, an eight-man, one-night tournament made up of the world's best heavyweights and light heavyweights held in Tokyo, Japan. He faced Ernesto Hoost in the quarter-finals, and after a close three rounds, Hoost was named the winner by majority decision (29-28, 30–28, 30-30). He returned to K-1 on September 4, 1993, against Dino Homsey at K-1 Illusion and KO'd the American with a left high kick in round one. Fifteen days later in Amsterdam, Aerts made the first defence of his WMTA World Heavyweight Muay Thai Championship against Rob van Esdonk, knocking him out with a right hook less than a minute into round four. 1994–1995: Successive K-1 World Grand Prix Championships Aerts knocked out Markus Fuckner of Germany on February 20, 1994, in Amsterdam to retain the WMTA Heavyweight Muay Thai title before heading out to Japan to take part in the K-1 Grand Prix '94 which was held in Tokyo on April 30, 1994. In the quarter-finals, Aerts was drawn against Rob van Esdonk whom he had defeated in the Netherlands six months earlier. Van Esdonk knocked Aerts down in round one but Aerts was able to come back and KO him with a right high kick. In the semis, he faced Patrick Smith, an American with a wild, aggressive style. Aerts was still able to handle him, however, and KO'd him just over one minute into the first round. Progressing into the final, he came up against Masaaki Satake for the second time. Aerts simply landed more powerful and a larger number of strikes on Satake en route to a unanimous decision (27-25, 30–25, 30–29) victory. This made him the 1994 K-1 World Grand Prix Champion. He returned to the ring on September 12, 1994, at the Night of the Stars tournament in Rotterdam. At the quarter-final stage, he faced Rob van Esdonk for the third time and Lumberjack'd him with the high kick again. He then knocked out Glenn Wijngaart in the semis and went into the final against Frank Lobman, who was thirty-eight at this point and facing Aerts for the third time. Aerts battered Lobman until his corner threw in the towel in round two. Aerts then made the third defence of his WMTA World Heavyweight
