He returned to the United States in 1995, briefly working for World Championship Wrestling (WCW), before beginning his most well-known stint in ECW, where he quickly became a fixture of the promotion.

[citation needed] Sabu debuted in Eastern Championship Wrestling (ECW) in October 1993 as a villain at NWA Bloodfest by defeating The Tazmaniac.

One of the most notable aspects of Sabu's early career was his refusal to speak,[4] a gimmick that he inherited from The Sheik (who never spoke English in public to protect kayfabe).

In his early career, Sabu was billed as being from Saudi Arabia, or Bombay, India (in real life he is a second generation Lebanese American from a suburb of Detroit).

[citation needed] Brunk revealed in a shoot promo and in the documentary film Forever Hardcore that in fact it was not Paul Heyman that brought him into ECW but that he was at the right place at the right time.

According to the storyline, Sabu, who at that time often arrived to the ring by his handler 911, was an uncontrollable madman strapped to a gurney and with a Hannibal Lecter-style face mask while trying to break free (he claimed to hate this part of his gimmick as he was normally tired before he started his match).

Sabu then headlined the inaugural November to Remember event on November 13 by teaming with Road Warrior Hawk in a title versus title dream partner tag team match against Terry Funk and King Kong Bundy, with Sabu's ECW Heavyweight Championship and Funk's ECW Television Championship on the line.

[citation needed] Sabu received a rematch for the Heavyweight Championship against Funk in a Three Way Dance at The Night the Line Was Crossed on February 5, 1994, also involving Shane Douglas.

Sabu would then continue to retain the Television Championship against the likes of Pat Tanaka and Mike Awesome, before losing the title to The Tazmaniac, which aired on the March 15 episode of Hardcore TV.

[citation needed] On May 3, 1995, Sabu defeated Koji Kanemoto at Wrestling Dontaku in the Fukuoka Dome to win the IWGP Junior Heavyweight Championship.

[citation needed] Sabu made his final appearance with NJPW on December 11, 1995, in Osaka, teaming with Hiro Saito to defeat Dean Malenko and Wild Pegasus.

He would embark on a winning streak against the likes of Cactus Jack at Holiday Hell, Stevie Richards at House Party, and Mr. Hughes at Big Apple Blizzard Blast.

Sabu received various title shots against Scorpio at CyberSlam, Just Another Night, and Big Ass Extreme Bash, but the matches ended in twenty-minute time limit draws.

One memorable moment occurred at this show when Sabu appeared during a match and prepared for an aerial move off the "R" in the "RAW" lettered entryway onto Team Taz members, but accidentally fell off the "R".

Sabu avenged that by interfering in Taz's match against Shane Douglas for the World Heavyweight Championship at Guilty as Charged, attacked both men and left.

On April 29, 2000, he won a tournament for the vacated XPW World Heavyweight Championship defeating John Kronus in the first round, Damien Steele in the second and The Messiah in the finals.

[citation needed] Sabu debuted in Total Nonstop Action Wrestling (TNA) on July 17, 2002, defeating Jerry "Malice" Tuite in a ladder match.

[citation needed] Sabu continued his feud with Abyss, once again losing to him at Genesis after taking a Black Hole Slam onto a barbed wire steel chair.

[citation needed] Shortly after his TNA release, on April 24, 2006, Sabu's official website reported that he had signed a one-year contract with World Wrestling Entertainment.

At this point, the WWE medical staff rushed to the injured men and declared neither man could continue and ordered the match stopped, resulting in a No Contest in which Mysterio kept his title.

[citation needed] On the June 13 premiere of ECW on Sci Fi, Sabu won a 10-man Extreme Battle Royal with the stipulation that the winner face John Cena at Vengeance.

On July 2, Sabu, traveling with fellow ECW wrestler Rob Van Dam, was arrested and charged with possession of drug paraphernalia, and nine Vicodin tablets following a traffic stop in Hanging Rock, Ohio following a house show in Huntington, West Virginia.

Towards the end of July, Sabu began to talk on camera for himself – instead of using a go between – and demanded a shot at Big Show's ECW World Championship which Paul Heyman refused to grant him in order to "protect" his champion.

At December to Dismember, Sabu was originally set to appear in the main event, an Extreme Elimination Chamber match for the ECW World Championship against Big Show, Test, Rob Van Dam, CM Punk and Bobby Lashley, but was "taken out" and replaced by Hardcore Holly.

Sabu came out during the main event and put La Parka through a table, joining forces with the heels X-Pack, Ron "The Truth" Killings, and Konnan.

[28] In 2007, Sabu teamed with Insane Clown Posse to defeat Trent Acid and the Young Alter Boys at Juggalo Championship Wrestling's Bloodymania.

Styles, Kazarian, Robert Roode, James Storm, Douglas Williams and Matt Morgan of Ric Flair's Fourtune stable, who thought they didn't deserve to be in TNA.

[45] At Bound for Glory, Sabu, Tommy Dreamer, Raven, Rhino and Stevie Richards defeated Fortune members Styles, Kazarian, Morgan, Roode and Storm in a Lethal Lockdown match.

He defended his title in a Fatal Four-Way elimination match on April 1, 2013, for CEW in St. Lawrence, NL against Justin Lock, Tony King and Brandon Flip.

[62] On May 24, 2023, Sabu made his debut for All Elite Wrestling on Dynamite[63] when it was revealed that he would come out of retirement for a one-off in the corner of Adam Cole along with Roderick Strong during his unsanctioned match with Chris Jericho at the Double or Nothing pay-per-view.
