In Chapter 1017 It is revealed that Queen is a former member of MADS, an illegal scientific research team that was active over 24 years ago.
Not much is known yet about MADS, except that it consisted of a team of expert scientists intent in studying and developing weapons for unknown purposes. One of their most notable accomplishments includes the discovery of the Lineage Factor, also known as the “blueprints of life itself”.
“MADS” could be a reference to “Mad Scientist”, a common term used in fiction to describe scientist characters who partake in unethical experiments
They were notable enough that the World Government felt threatened by their existence, leading to their persecution and eventual disbandment.
So far, only three former members of MADS have been revealed: Dr. Vegapunk, currently considered the world’s greatest scientist and head of the Marines’ SSG; Vinsmoke Judge, the supreme commander of Germa 66 and king of Germa Kingdom; and Queen, a cyborg and one of the Beasts Pirates All-Stars.
All of the known members have been proven to be brilliant researchers in their own right, holding high status in the organizations they currently belong to and being responsible for various scientific breakthroughs, including cybernetics, cloning, and artificial diseases.
As we have seen, Queen employs several cybernetic augmentations that assist him in battle. He has multiple high-technological weapons and mechanisms installed within his body, which he usually activates while employing his Zoan abilities. In his full brachiosaurus form, he has a double-barreled Gatling gun, artificial fangs and a laser beam cannon equipped inside his mouth. Moreover, his neck area is modified with some sort of in-built mechanical cable that allows him to extend his already long brachiosaurus neck beyond its normal range. He also has retractable needles in his teeth.
Queen’s hybrid form displays a different set of modifications, such as clawed tentacle appendages located on his tail and braided hair. His prosthetic left arm also changes shape, sporting a claw similar to the aforementioned appendages.
