Brandon Silvestry (born September 6, 1979) is an American professional wrestler, better known by his ring name Low Ki. He is known for his time with TNA Wrestling, Ring of Honor and Major League Wrestling as Low Ki and Senshi and with WWE as Kaval.

He is a one-time PWG World Champion, the inaugural ROH World Champion, one-time MLW World Heavyweight Champion and a three-time NWA World Tag Team Champion, and has won a number of tournaments and other championships on the independent circuit, and was the winner of the second season of NXT in 2010. Silvestry has also worked extensively in Japan, most notably for New Japan Pro-Wrestling (NJPW), where he was a three-time IWGP Junior Heavyweight Champion, and Pro Wrestling Zero-One (Zero-One), where he was a one-time Zero-One International Junior Heavyweight and NWA International Lightweight Tag Team Champion. He is a three time world champion, and is the only wrestler in history to have been ROH, PWG, and MLW World Champion.

Silvestry began wrestling in late 1998 under the ring name Low Ki, which he derived from the lyrics of the song "No Diggity". He began wrestling for Jersey All Pro Wrestling (JAPW) in 1998, challenging Homicide and Kane D for the JAPW Tag Team Championship. The following year he challenged for the JAPW Light Heavyweight Championship twice, unsuccessfully, but defeated Crazy Ivan and Judas Young to win the second Best of the Light Heavyweights tournament.

In 2000, he began making several appearances in the World Wrestling Federation on their programs Metal and Jakked, where he competed against the likes of Raven, Crash Holly, Christian and Essa Ríos. The following year he made it through to the finals of All Pro Wrestling's King of the Indies tournament, losing the crown to American Dragon. It was also during 2001 that he defeated Nick Berk and Homicide in separate matches on the same evening to win both the JAPW Heavyweight and Light Heavyweight Titles; he would successfully defend both titles in separate matches at their Fourth Anniversary Show later that month in July. He lost both titles in a Three Way match the following month to Homicide, with Xavier as the other competitor.

Low Ki made his Ring of Honor (ROH) debut at its first show, The Era of Honor Begins, on February 23. In the show's main event, he defeated Bryan Danielson and "The Fallen Angel" Christopher Daniels. On July 27, 2002, at Crowning a Champion, he became the first ever ROH Champion by defeating Daniels, Spanky and Doug Williams in a Four Way Ironman match. On August 24, Low Ki successfully defended his title against A.J. Styles. On September 21, at Unscripted, he lost the title to Xavier, who, after winning the title, became a member of Daniels's faction The Prophecy. Low Ki then faced Samoa Joe on October 5 in what was Joe's official ROH debut in a "Fight Without Honor". In what resembled more of an MMA fight, Low Ki won the match and they shook hands after the match. Low Ki left the promotion in 2004 due to the Feinstein incident, but he returned on July 17, 2004, during a match, where Samoa Joe and the Briscoe Brothers fought against The Rottweilers (Homicide and the Havana Pitbulls). It looked like Low Ki would save Samoa Joe from a beatdown by The Rottweilers, but instead he spat on the ROH Championship, which was then held by Joe, and joined The Rottweilers.

At Weekend of Thunder Night 2 on November 6, 2004, he started a feud with Bryan Danielson, who was Low Ki's partner in a match against Samoa Joe and Jushin Thunder Liger. Low Ki and Danielson lost the match and Low Ki blamed his partner for that, so The Rottweilers started a beatdown on Danielson. On December 4, at All Star Extravaganza II, Danielson defeated Homicide of The Rottweilers. In that same event, Low Ki wrestled Austin Aries in a number one contender's match to determine who would face ROH Champion Samoa Joe for the title. The match ended in a draw. Officials extended the match, but Low Ki refused to wrestle, so Aries was declared the winner. Instead of facing Joe at Final Battle 2004, Low Ki wrestled Danielson, but got himself disqualified and then attacked the referee. This was enough for ROH officials to suspend him indefinitely as a result.

Low Ki returned on May 7, 2005, and immediately attacked Jay Lethal and Samoa Joe at Manhattan Mayhem with his fellow Rottweilers, Homicide, Julius Smokes, Monsta Mack and Rocky Romero. The impromptu tag team match was made: The Rottweilers vs. Samoa Joe and Jay Lethal. Low Ki and Homicide won the match and injured Lethal with a Ghetto Stomp/Cop Killa combination. The feud continued on June 18 at Death Before Dishonor III, where he and Lethal faced each other in a singles match, but it ended in a no contest. They had a rematch on August 12 at Redemption, but the ending was the same and Rottweilers beat Lethal down after the match. Finally, on September 17 at Glory By Honor IV, a "Fight Without Honor" between the two ended with Low Ki getting a pinfall victory over Lethal. After Samoa Joe went on to save Colt Cabana from a beatdown by The Rottweilers, Lethal came out to even the odds and said that he wanted yet another rematch with Low Ki, which Lethal won this time, ending the feud. Later in the year, Low Ki helped Homicide in his feud against Colt Cabana. On December 17, 2005, at Final Battle 2005, he challenged Kenta for his GHC Junior Heavyweight Championship, but came up short. Low Ki left ROH once again in January 2006 due to a "disagreement in business arrangements". He won his last match on January 28 against Jack Evans. ROH covered his leaving by having the ROH commissioner Jim Cornette ban Low Ki from Ring of Honor for life after it was discovered that he was the one who knocked Cornette's tooth out at that show. He was also used as a focus point (in name only) in the Cornette/Homicide feud in the summer of 2006, with Cornette refusing to reinstate Low Ki as Homicide's "third wish."

Low Ki's first stint with NWA Total Nonstop Action (NWA TNA) was for its debut show on June 19, 2002, in a six-man tag team match alongside A.J. Styles and Jerry Lynn against the Flying Elvises. On June 26, he attempted to become the first X Division Champion, but was beaten by Styles. He would, though, eventually go on to win the title from Styles on August 7, but lost it three weeks later to Lynn. He would later form the Triple X faction with Christopher Daniels and Elix Skipper that year and hold the NWA World Tag Team Championship three times under the "Freebird Rule". Low Ki wrestled beside Skipper when Triple X defeated America's Most Wanted (Chris Harris and James Storm) for the title on January 22, 2003. When Daniels's greed for the X Division Championship initially forced Low Ki out of Triple X, Low Ki would go on to battle Daniels in Ultimate X, but his pursuit was unsuccessful. He left NWA TNA in July 2004 and made his return to ROH.
