General profile

The Shy Guy is one of the most recognizable and best-loved Mario series enemy species, distinguished by the masks they wear because of their shyness. Introduced in 1987 in Yume Kojo: Doki Doki Panic for the Famicom Disk System (and retained for the 1988 Western Super Mario Bros. 2 release), Shy Guys are short creatures in robes and white circular masks with three holes for the eyes and mouth. They are normally red, but they come in many other colours. What lies behind the mask is a long-running mystery that characters such as Luigi in Mario Power Tennis have tried to solve.

Shy Guys’ broader Mario series role has expanded substantially since their debut. Originally members of Wart‘s army, the 8 bits, they have been associated with Bowser since Super Mario World 2: Yoshi’s Island, appearing among Bowser’s minions in the Yoshi, Paper Mario and Mario & Luigi series. They turn up across nearly every Mario sub-genre: platformers, Mario Kart (on the full roster since Mario Kart 7), Mario Party, Mario Tennis, Mario Strikers, Mario Sports Mix and the RPGs.

Shy Guys come in many colours: red is the default, and blue, green, yellow, pink, black, white, light-blue and orange Shy Guys have all appeared. The species has also spawned a huge family of variants, including Fly Guys, Spy Guys, Pyro Guys, Snifits, Spear Guys and Stilt Guys.

Quotes

"I ain’t scared… I’m terrified!" — Shy Guy, Paper Mario: Color Splash
"I’m not bold enough to go on real adventures, so I made my board look just like a wild jungle!" — Shy Guy, Mario Party 4
"…Oh, huh-hello. My name is Shy Guy." — Shy Guy, Mario Party Advance

Enemies

The Shy Guy species’ primary enemies are Mario, Luigi, Yoshi, and the wider Mushroom Kingdom heroic cast. Originally serving Wart in Subcon, the species transitioned to Bowser’s Koopa Troop after Super Mario Bros. 2, making them opposed by default to essentially every protagonist faction in subsequent Mario series entries. They are especially common enemies in the Yoshi series, and they appear alongside Goombas as enemies in the Paper Mario and Mario & Luigi RPGs.

Friends

Shy Guys’ loyalties are split between Bowser’s Koopa Troop service and occasional good-aligned individual exceptions. The mainstream Shy Guy species serves Bowser as rank-and-file foot soldiers, but several notable individual Shy Guys have aligned with Mario or with neutral parties. Captain Shy Guy is an unlockable captain in the Minion Quest: The Search for Bowser mode of Mario and Luigi: Superstar Saga + Bowser’s Minions (2017), helping Bowser’s troops rescue their king. In Mario and Luigi: Bowser’s Inside Story (2009), a Shy Guy corps serves Bowser and the notable Sergeant Guy makes his debut, while a friendly Shy Guy explorer hosts Shy Guy’s Jungle Jam in Mario Party 4.
