Michelangelo Buonarroti

Michelangelo di Lodovico Buonarroti Simoni, referred to simply as Michelangelo Buonarroti or Michelangelo, was a famous artist and sculptor responsible for numerous works of art, including the Sistine Chapel's ceiling, David, Pietà, and Moses. As depicted in the SNES release of Mario's Time Machine, he is pompously aware of his ability, and he considers himself to be the greatest artist of the Renaissance.

Mario is Missing
In Mario is Missing!, Michelangelo is briefly mentioned in a pamphlet, which was handed out after the Sistine Chapel's ceiling was stolen by Bowser. According to the pamphlet, Michelangelo was commissioned by Pope Julius II in 1508 to add art to the ceiling. He was not used to painting with plaster, and the entire project took over four years to complete. He completed most of the art while either uncomfortably lying down on scaffolds or craning his neck straight up, though the end result is often stated to be his best work.

Mario's Time Machine
According to Mario's Time Machine, in 1505, he lived in Florence, where he worked on the Sistine Chapel in his workshop. He is first encountered by Mario after the latter goes back in time to return Leonardo da Vinci's Notebook, since Bowser had stolen it. In their first encounter, Michelangelo mostly boasts about how nobody can compare to him, with the possible exception of Leonardo. However, he quickly dismisses him since he focuses on domains outside of art such as engineering and science. He then mentions a new project of his, but refuses to elaborate further until he receives some plaster. Once Mario brings him a Bucket of Plaster from one of Verrocchio's apprentices (which can only be delivered once Michelangelo specifically mentions that he needs plaster), he goes on to explain that Pope Julius II commissioned him to paint the Sistine Chapel's ceiling in frescos; although he only wants to create sculptures, he cannot refuse a request from the Pope. Mario then changes the topic and asks about Lady Giocondo, which reminds Michelangelo that she left her mirror in his workshop when she came to visit. He then gives Mario Mona's Mirror and asks him to return it to her.
