The 12th PTW Underground show was held on Sunday, February 26, 2023, in PTW Performance Center in Chorzów.
The show had one new foreign guest: Hungarian wrestler Iva Kolasky, former WxW Women's Champion, facing Diana Strong. This was her only appearance for PTW so far, but not her first match against Diana - the two faced in WxW Academy in March 2022, and would meet each other again in Finland and Budapest later in 2023.
In the inaugural tournament for the PTW Tag Team Championship, fans saw the first team advance to the finals.
