Ruas was born in
Rio de Janeiro, Brazil in 1961. He started his career training
Boxing,
Taekwondo,
Judo, and
Capoeira, the latter with renowned
José Tadeu Carneiro Cardoso in Rio de Janeiro at the Santa Luzia club, downtown Rio. However, his primary martial arts eventually became
Luta Livre, which he trained under
Roberto Leitão Sr., and
Muay Thai, which he trained under Luiz Alves, a student of Nélio "Naja" Borges, the man who introduced Thai boxing to Brazil. After the match against Pinduka, he started training in Brazilian jiu-jitsu with Osvaldo Alves. Later he trained
Joe Moreira before his fight against the Russian boxer Yuri Vaulin. Seeing his good skills in grappling, Moreira gave him a black belt in Brazilian jiu-jitsu and caused a commotion and controversy among his fellow Brazilians, due the rivalry between the two martial arts. His instructors included
Euclydes Hatem. Eventually, Ruas became famous among the Brazilian martial arts circle and one of the most regarded non-BJJ fighters in Brazil due his philosophy of
Cross-Training and in synthesizing all martial arts he knew for both Vale Tudo contests and self-defense into a new
hybrid martial art he dubbed "Ruas Vale Tudo". In 1991 he was going to participate in
Desafio - Jiu Jitsu vs Luta Livre, an event fought as a challenge between fighters from the two martial arts, Ruas was cast to fight BJJ representative
Amaury Bitetti but cancelled his participation and Bitetti was declared winner by
W.O. Instead, in 1992 he promoted his own event in
Manaus where he defeated Francisco Borges with a
rear naked choke. Eventually he attracted the attention of Brazilian manager and fight promoter
Frederico Lapenda and was able to get the 34-year-old fighter into the
Ultimate Fighting Championship. He firstly faced Larry Cureton, who outweighed him by 40 lbs, but Ruas submitted him with a
heel hook after a methodical grapple. His next opponent was the judoka
Remco Pardoel, who early tried a
guillotine choke, but Ruas blocked it and grinded him with foot stomps. After a failed heel hook attempt, Ruas controlled Pardoel and attacked him with knees and punches on the ground, making him tap out. Ruas's final fight was against 6'8", 330 lb
Paul Varelans, and he showed his muay thai skills by overwhelming Varelans with punch combos and repeated leg kicks. He also used again his characteristic foot stomps when Paul clinched him against the cage. At the end, Varelans could not take more kicks to his legs and fell to the ground, where Ruas pounded him until the referee stopped the fight, giving Ruas the victory of the tournament. Thanks to his victory in UFC 7, Ruas was invited to the
Ultimate Ultimate event. He defeated
Keith Hackney by choke with ease, but his next opponente,
Oleg Taktarov, made a tougher contest. Both fighters used a passive approach to the fight, with Ruas blocking Taktarov's takedown attempts and seizing all the opportunities to strike him, actually making him bleed profusely. However, the judges gave the decision win to Taktarov, and Ruas was eliminated from the tournament. This decision was met with controversy, and Ruas and his cornermen appealed to the referee, but nothing came from it. In 1996 he joined the nascent World Vale Tudo Championship (WVC) organized by his manager
Frederico Lapenda, fighting in the superfight against
UFC 3 Tournament Champion Steve Jennum in
Tokyo,
Japan. He won easily with a submission to punches and won the WVC Superfight belt. Almost a year after his last UFC fight, he faced Taktarov again in Brazil, in a bout with no judges. The rematch ended in a draw, but Ruas was clearly the most dominating fighter, and he shook hands with Oleg after the fight. He kept the WVC Superfight belt in the process. He finished his run in the organization with his last superfight against
UFC 2 finalist
Patrick Smith in the WVC 4 event, easily winning with a heel hook. Ruas briefly joined the stable of Antônio "Sebastião" Lacerda, a wealthy man from the north of Brazil and self-proclaimed "Master of Death" who appeared in Rio de Janeiro in 1996 claiming to have spent a long period of time in Japan learning "the deadly art of
Yawara." Despite his dubious credentials, Lacerda was able to recruit some established competitors into his sect, including Ruas and Edson Carvalho, a judo national team member and a
Carlson Gracie black belt. Seeking opportunities to compete professionally, Ruas began training with Lacerda after Lacerda promised to take him to lucrative competitions abroad, on the condition that he agree to merge his style of vale tudo with Lacerda's techniques. Ruas parted ways with Lacerda when he began to question the effectiveness of Lacerda's techniques and practices, but Carvalho continued participating in Lacerda's challenge, constantly attacking not only jiu-jitsu but all fighting styles. He was then invited to
PRIDE Fighting Championships in 1998, he first had a match against UFC veteran
Gary Goodridge at
PRIDE 2, winning with a heel hook after a 9-minute bout. At
PRIDE 4 he fought Japanese
shoot wrestler Alexander Otsuka. In a major
upset, Otsuka fought with tenacity, taking Ruas down and performing
ground-and-pound, defending a fully locked
rear naked choke and forcing a TKO by medical stoppage in the second round. It was later revealed that Ruas fought under medication for
Hepatitis and a knee injury. He returned briefly to UFC to fight former heavyweight champion
Maurice Smith in
UFC 21, but lost by TKO. Ruas suffered an injury in the first round and could not continue. Around that time, Ruas started to transition from a fighter into a full-time coach, teaching his own "Ruas Vale Tudo" style for a new generation of fighters. Some of his students include UFC light-heavyweight contender
Pedro Rizzo and
Strikeforce light-heavyweight champion Renato Sobral. He also coached
UFC Featherweight Champion José Aldo in Luta Livre, awarding him a
black belt in the art, and Aldo was also coached striking and
leg kicks by Pedro Rizzo, some of Ruas's own fighting style can be seen in Aldo's. At this point semi-retired, in 2001 Ruas defeated
Jason Lambert at Ultimate Pankration in California in less than 1 minute with a heel hook. Marco Ruas was invited to participate in the newly formed MMA promotion
International Fight League (IFL). This promotion would be divided into different teams (later becoming simply MMA camps) instead of one-on-one affairs, and at the end one of the seasons one of the teams/camps was crowned champion. Ruas coached the "
Southern California Condors" team, later simply known as "Ruas Vale Tudo". He also came out from retirement and had one rematch against
Maurice Smith (which coached the IFL's "Seattle Tiger Sharks") as the superfight for the
IFL: Chigaco event in 2007, which he lost by TKO with a stoppage by his corner. Marco Ruas then fully retired from the sport with a record of 9 wins, 4 losses and 2 draws. == Personal life ==
