Several Marvel comic books were stamped with the blood of comic book writer Stan Lee, a new report claims, wrote dailymail.co.uk.

Lee's blood was allegedly stolen in October and then used to create blue and gold 'DNA ink' to sign several recent copies of Marvel Comics - The Mighty Thor #700 and a variant cover of Rise of the Black Panther #1, TMZ reports. 

According to the outlet, Lee's former business associate allegedly forged medical documents giving him access to the comic book legend's blood. 

He then took the bogus paperwork to Lee's personal nurse and had her fill several vials with Lee's blood.

TMZ claims the nurse allegedly took so much blood it made the 95-year-old dizzy.  

The alleged stolen blood was only recently discovered by Lee's friend and partner Keya Morgan. Sources told the outlet that Lee's team first thought that the stolen blood would be turned into pens containing an ink substitute.

They later found out that the blood had allegedly been used to sign several comic books. The comic books were being sold at the Las Vegas Marvel Avengers S.T.A.T.I.O.N., an officially licensed exhibition and retail store based on Marvel's Avengers.

According to the report, each hand-stamped comic book contained an authenticity certificate stating that it was 'hand-stamped with Stan Lee's Solvent DNA Ink'.   

The Black Panther comic books came in either blue or gold DNA ink. The blue sold for $250 and the gold for $500.

A legal representative for the Avengers S.T.A.T.I.O.N. store told TMZ: 'We're a retail store which purchased product from Hands of Respect LLC and DLK Brand Consulting LLC that appeared certified and obtained with authorization. The books were removed from our shelves immediately.'

Lee's team also thinks the former business partner who swiped the blood took $300,000 from the comic book legend and purchased an $850,000 condo with Lee's money.
