A tattooist, who was known as Dr Evil, has been jailed for carrying out ear and nipple removals and splitting a customer's tongue.
Brendan McCarthy carried out consensual procedures but without using aesthetic.
He pleaded guilty to three counts of grievous bodily harm and was jailed at Wolverhampton Crown Court for 40 months.
Passing sentence, Judge Amjad Nawaz said the body-modification industry was unregulated and McCarthy was only registered as a tattooist and cosmetic piercer.
The judge said of McCarthy: "He had no qualifications to carry out surgical procedures or to deal with any adverse consequences which could have arisen.
"There is a clear public interest element. There is also a need for deterrent."
'The defendant is plainly remorseful'

The man whose ear was removed in 2015 was contacted by police after McCarthy pleaded guilty last month, the court heard.
In comments to police, read into the record by Mr Grieves-Smith, the man said he "felt like he had been deceived" as he thought at the time that the procedure was legal.
Mr Grieves-Smith said: "He stated that had he known it was illegal, he would never have had the procedure because he certainly was not that desperate to have his ear removed."
Defence QC Andrew Smith had urged the Judge not to jail McCarthy - who now has "no direct engagement with customers" - in the "unusual" case.
Accepting that McCarthy had caused harm, Mr Smith added: "Each individual actively sought the procedures. It came about as an extension of the work he had historically undertaken in respect of body-piercing and tattooing.
"The defendant is plainly remorseful... expressed through pleas of guilty and expressed in his discussion with the Probation Service."
