Early career (2012–2013) Littlejohn began wrestling with the promotion
Beyond Wrestling, where he competed as Leech Landa in a match in
Philadelphia in September 2012. In 2013, he appeared in two matches with the promotion Wrestling Is...Respect! in
Boonton, New Jersey. The
kayfabe reason for his
ring name came from when he was bullied in a segment by
Charlie Haas, but it was a name he acquired three years earlier, following a remark from
Rhett Titus. In 2014, Cheeseburger twice unsuccessfully challenged
Jay Lethal for the
ROH World Television Championship: at the promotion's
Second to None event in
Baltimore and its ''Road to Best in the World '14'' show in
Carbondale, Illinois. Cheeseburger was a part of a tag team called
Brutal Burgers, teaming with
"Brutal" Bob Evans. The two wrestlers feuded after the tag team split, culminating in the
Final Battle kickoff, where Cheeseburger defeated Evans. In January 2016, Cheeseburger made another challenge to the World Television Championship, this time falling short against Roderick Strong in
Collinsville, Illinois during ROH's Winter Warriors Tour. During the COVID Pandemic, Littlejohn thought about his career and his character, and seeing the Cheeseburger character as stagnant, so he decided to change his gimmick. The week of Monday, February 1, 2021, Littlejohn announced on Twitter that he would no longer be using the "Cheeseburger" ring-name. It was revealed on ROH TV the following Friday, February 5 that he will now use the ringname "World Famous CB". a loss to The Trust Busters during the
Death Before Dishonor pre-show, and a loss to
Angelo Parker & Matt Menard at
Final Battle where he teamed with
Eli Isom.
New Japan Pro-Wrestling (2016–2018) On January 4, 2016, Cheeseburger made his surprise debut for
New Japan Pro-Wrestling (NJPW) by taking part in the
New Japan Rumble in the pre-show of
Wrestle Kingdom 10 in Tokyo Dome. He was eliminated from the match by
Yoshi-Hashi. Cheeseburger formed an on-screen friendship with NJPW wrestler
Jushin Liger, which led to him adopting Liger's
Shotei palm strike as a finishing move. The following day, Cheeseburger teamed up with
Hiro Saito,
Hiroyoshi Tenzan,
Satoshi Kojima and
Scott Norton in a ten-man tag team, where they defeated
Bullet Club (
Bad Luck Fale, Bone Soldier,
Kenny Omega,
Tama Tonga and
Tanga Loa). At

Masahito Kakihara to end the match. At
New Year Dash !! the next night, he teamed with
