World Wrestling Federation (1998–1999)

After turning pro in late 1997, Silva signed with World Wrestling Federation. After debuting he was given the name: "Giant Silva" and was a member of the Oddities stable. For most of his WWF tenure, Silva was a cornerman for the Oddities and his matches on TV were tag matches, teaming up with Golga and/or Kurrgan.^[5] His only highlight was at SummerSlam 1998 when he, Golga, and Kurrgan defeated Kai En Tai in a 3 on 4 Handicap match. During his time in WWF, Silva was not used as much. Silva was released around February 1999.

He would return only once with long hair on the July 4, 1999 episode of WWF Super Astros in a victory over Pantera.

Consejo Mundial de Lucha Libre (1999–2003)

After his WWF tenure, Silva joined Mexican promotion Consejo Mundial de Lucha Libre and was renamed Gigante Silva. He was introduced by midget wrestler Tzuki and soon became an ally to tecnicos, often teaming up in tag team matches against numerically superior rudos. Silva struck an occasional team with fellow superheavyweight Brazo de Plata and had part in a feud with Gigante Kurggan, who was brought by Los Capos (the faction led by Apolo Dantes and Universo 2000) in order to oppose him. In November 2003, Silva turned rudo himself and allied with Pierroth Jr. and his valet La Comandante before leaving Mexico for Japan full time.

New Japan Pro-Wrestling and Hustle (2001–2008)

In 2001, Silva joined New Japan Pro-Wrestling. He originally debuted on August 12, 2001 as a member of Masahiro Chono's stable: Team 2000^[6] where he was paired up with another Giant: Giant Singh (better known as The Great Khali) as the tag team: Club 7. Silva made his in-ring debut for New Japan when he took part in the G1 World Climax tournament where he finished in 4th place with 4 points.^[6] He and Singh made their debut as a tag team at Indicate of Next on October 8, 2001 where they defeated Hiroshi Tanahashi, Kenzo Suzuki, Yutaka Yoshie, & Wataru Inoue in a 4 on 2 handicap match.^[7]

In the fall of 2001, Silva teamed with Chono in the 2001 G1 Tag League with the team finishing in 7th place with 6 points.^[8] In 2002, Silva took part in several tournaments. In February he was part of the a tournament for the vacated IWGP Heavyweight Championship but lost in the first round to eventual winner: Tadao Yasuda.^[9] Two days later on February 3, Silva, Singh, and Chono won the Teisen Hall Cup 6 Man Tag Team Tournament.^[9] In March, Club 7 then entered a tournament for the vacated IWGP Tag Team Championship.^[10] In the first round, they defeated fellow Team 2000 members: Scott Norton and Super J, but lost to Yuji Nagata and Manabu Nakanishi in the semi-finals.^[10]

In the spring of 2002, Club 7 broke up and began feuding shortly afterwards. The two were scheduled to face each other at Toukon Memorial Day on May 2, 2002 but an injury to Singh prevented the match from taking place.^[11] The two finally fought at Cross Road on August 29, 2002 with Silva defeating Singh.^[12]

From 2004–2008, Silva wrestled for HUSTLE where he took part in a variety of matches and formed teams with Scott Norton, Toshiaki Kawada, and Mark Coleman.^[13]

Independent circuit (2008–2010)

Silva also competed in National Wrestling Superstars mainly working in handicap matches.

Pride Fighting Championships (2003–2006)

After his career in NJPW, Silva was signed by Dream Stage Entertainment and competed in Pride Fighting Championships, a defunct mixed martial arts organization based in Japan. Although at one time he trained with members of the Gracie family, most notably Ricardo Gracie and Ralek Gracie, he only had a crash course in Brazilian jiu-jitsu when he had his debut at Pride Shockwave 2003 against 250lbs Heath Herring. Silva led the more experienced fighter to the third round, absorbing repeated leg kicks and taking Herring down once, but Heath capitalized and reversed it into a rear naked choke for the win.

In April 2004, Silva took part in the Heavyweight Grand Prix tournament, whose first round saw him facing sumo wrestler Henry "Sentoryu" Miller, only 85lbs lighter. Sentoryu accomplished a takedown on Silva and attacked his guard, only for Silva's height to neutralize his ground and pound attempts, as the sumo wrestler could not reach his head. Miller finally got side control, but then Silva reversed him with a Kimura lock and made him tap out. The pro wrestler then advanced to the second round, being pitted against former world judo champion Naoya Ogawa, who won the fight by ground and pound TKO.

Silva would then face another professional wrestler, Pro Wrestling NOAH's Takashi Sugiura, who used his wrestling acumen to take Silva down and land knees and punches for the stoppage. The match had some controversy, as a brawl erupted after the bout and Silva had to be restrained by several ring crew men.^[14]

On December 31, 2006 Giant Silva finally faced a heavier opponent, the former yokozuna Akebono Tarō, at K-1 Premium 2006. The sumo wrestler clinched Silva and pressed him against the ropes, until Silva broke the hug and transitioned to a Kimura lock on the ground, submitting Akebono for his second and last win.
