There is no question that the Super Mario Bros series has been legendary since the NES days of the 80’s. Both Mario and Luigi are considered to be an iconic duo in relation to platform adventure games and things have been this way over 30 years now on Nintendo based game consoles. However, some wonder how different the Mario series could have ended up becoming if Luigi started off as a villain before joining his brother Mario. On one hand starting off as a villain could off helped Luigi’s popularity in major way. The idea of having Luigi as a video game boss in one of the first three Super Mario Bros titles would have been very interesting and would of made people look at him much differently then they currently do right now.
As it currently stands characters such as Yoshi are considered to be more popular than Luigi especially considering how many games there has been within the Yoshi series since the early 90’s. Also, Wario was more popular than Luigi at some point especially when he started off as the main villain for Super Mario Land 2: 6 Golden Coins for Game Boy back in 1992. Wario was originally a villain before becoming a anti-hero and if Luigi had a similar role within the Super Mario Bros series it could of ended up making him a somewhat cooler than Mario who is often portrayed as a clean cut hero that rescues Princess Peach from the clutches of Bowser. In theory, having Luigi as a short term villain who transitions into becoming an anti-hero who works alongside Mario could have worked but Nintendo never intended on making Luigi a more edgier character than his brother.
