Low-Ki made his debut in
Ring Of Honor in its first show The Era of Honor Begins. In that show's main event he defeated "American Dragon"
Bryan Danielson and "Fallen Angel"
Christopher Daniels. On
July 27, 2002, at Crowning a Champion, Low-Ki became the first ever Ring Of Honor Champion by defeating Christopher Daniels,
Spanky and
Doug Williams in a Four Way Ironman match. On
September 21, 2002, at Unscripted, he would lose the title to
Xavier, who, after winning the title, became a member of Christopher Daniels stable
The Prophecy. Low-Ki left the promotion in 2004 due to the infamous Feinstein incident in ROH.
He returned to Ring Of Honor in 2004 during the match, where
Samoa Joe with
Jay &
Mark Briscoes fought against
The Rottweilers (
Homicide & the
Havana Pitbulls). It looked like Low Ki would save Samoa Joe from the beatdown by The Rottweilers, but instead he spat on the
ROH World Championship, which was then held by Samoa Joe, and joined the heel stable.
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. Ki & Danielson lost the match and Low Ki blamed his partner for that, so The Rottweilers started a beatdown on Danielson. On
December 4, 2004, at All Star Extravaganza II, Bryan Danielson defeated Homicide of The Rottweilers. In that same event Low Ki wrestled
Austin Aries in a #1 Contender's match to Samoa Joe's ROH World Championship. The match ended in a draw. ROH Officials extended the match, but Low Ki refused to wrestle, so the winner of the match became Austin Aries. Instead of facing Samoa Joe at Final Battle 2004, Low Ki wrestled Bryan Danielson, but Low Ki got himself disqualified and then attacked the referee. This was enough, for ROH Officials to suspend him indefinitely as a result.
Low Ki returned in 2005 and immediately attacked
Jay Lethal at Manhattan Mayhem with his fellow Rottweiler Homicide. The impromptu tag team match was made: The Rottweilers vs Samoa Joe & Jay Lethal. Low Ki & Homicide won the match and injured Lethal with a Ghetto Stomp/Da Cop Killa combination. The feud continued at Death Before Dishonor 3, where Low Ki and Lethal faced each other in a singles match, but it ended in a no contest. They had a rematch at Redemption, but the ending was the same and Rottweilers beat Lethal down after the match. Finally, at Glory By Honor IV, a match between the two ended with Low Ki getting a pinfall victory over Jay. It looked like the feud was over, but when Samoa Joe went on to save
Colt Cabana from a beatdown by The Rottweilers, Jay 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. He won his last match 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
Tag Wars 2006.
