Who is Katharina Thanderz? Facts you need to know below

On Saturday, November 14, Matchroom Boxing showcase some of the world’s leading female talent with a tiple world title header, featuring Katie Taylor vs Miriam Gutierrez in an undisputed lightweight match; Rachel Ball vs Ebanie Bridges for the vaant WBA bantamweight World title; and Terri Harper vs Katharina Thanderz for the WBC and IBO World super-featherweight titles, live on Sky Sports in the UK and DAZN in the US.

Not that much is known of the Norwegian to UK fight fans, so BBN dug up some info about ‘Katy’ here:


Katharina Thanderz was born on July 29, 1989, when Margaret Thatcher was the Prime Minister and Soul II Soul were number one in the UK charts with ‘Back to Life’. Katy was born in Oslo, the capital of Norway, and is currently 32-years-old.

Born to a Norwegian mother and a Spanish father, Thanderz spent the first seven years of her life in Oslo before moving to Altea, Spain, which is located in the Alicante region, where she resides and trains.

She began her combat career as a kickboxer at the age of 10.

She competed in the 2019 European Games in Belarus, which Team GB dominated that year, coming away with two golds (Pat McCormack and Lauren Price), one silver (Benjamin Whittaker) and four bronze medals (Galal Yafai; Peter McGrail; Luke McCormack; Cheavon Clarke) – three more medals than any other competing nation.

Her professional boxing debut was on May 27, 2016, beating winning fighter and Italian title contender Angela Cannizzaro (5-2 at the time) by unanimous decision – 40-36; 39-37; 38-37.

Her first six contests were in Spain between May 2016 and July 2017, then she returned to her native Norway to challenge for the European super-featherweight title against WBF World Female super-featherweight champion Maria Semertzoglou (6-2 at the time), from Athens, Greece, in October 2017. It was Semertzoglou’s second time challenging for the EBU belt, but she was defeated by an even wider margin than her first attempt as Thanderz registered a points score of 99-91 twice and 98-92. She became just the fourth champion of the title, after Myriam Chomaz; Eva Wahlstrom; and Angelique Duchemin.

She then added another title in her next fight with Iceland’s unbeaten Valgerdur Gudstensdottir (3-0 at the time) to collect the WBC International lightweight title. Terri Harper (10-0-1, 5KOs) won the exact same title, after Thanderz vacated it, almost exactly a year later to the day in March 2019 by defeating Nina Bradley (7-1).

In her last fight in November 2019, Katy moved up to 13-0 (2KOs) by defeating Brazilian Danila Ramos (8-2, 1KO) for the interim WBC World Female super-featherweight title.

She fought Birmingham’s Rachel Ball in March 2019, winning via majority decision despite breaking her hand in the fourth round.

She is presently ranked by BoxRec as the world’s ninth best super-featherweight. She also ranked as IBF #6 and IBO #7.

Thanderz has fought in three different countries so far – Spain (x8), Norway (x4) and Germany (once). Her bout with Terri Harper will be her first professional fight in England.
