He dedicates himself to fighting viruses using medicinal capsules. His medical adventure began in the video game Dr. Luigi, released for Wii U in December 2013 in Japan and North America, and in January 2014 in Europe. Although he doesn't always display the same confidence as Mario, Luigi compensates for his doubts with perseverance, creativity, and determination. His work as a doctor represents another facet of his personality: that of someone who, even when he feels fear or uncertainty, is willing to help others.
