Emblem

An emblem is a symbol that appears on an item used by a specific character in many of the Mario spinoff and main series titles, usually representing said character in some fashion; for example, Mario's emblem is the red M that is sewn on his cap, whereas that of Yoshi is his egg, or Rosalina is the Grand Star.

Description
Emblems have been used as early as Mario Tennis for the Nintendo 64, with each character's emblem inked on the strings of their respective rackets; the trend has been continued in all future Mario Tennis games since then.

Emblems would make an appearance in the Mario Kart series as well, starting with Mario Kart: Double Dash!!; certain karts have their respective character's emblem placed on the kart's body. Mario Kart DS and Mario Kart Wii give all characters that appear in either game a more streamlined emblem, most of which have been used in various other spinoff games since, including later Mario Kart games. Like in Mario Kart: Double Dash!!, these emblems are applied on the kart, bike or ATV. Starting with Mario Kart 7, certain gliders would also depict the character's emblem. Mario Kart DS also introduced emblem customization, a feature currently exclusive to that game where players can create their own icons using the Nintendo DS Touch Screen, which were displayed during online matches.

In the Mario Party series, emblems first appeared in Mario Party 7, where they were used to denote who controlled Character Spaces (created when someone placed an Orb on a space); when using team-based rulesets, the game instead uses one of two (or four) preset team emblems. They also appear in Windmillville, denoting ownership of a particular windmill and the Stars tied to it. In Mario Party 8, an emblem appears next to the character to indicate when it is the character's turn during gameplay; Koopa's Tycoon Town also uses a similar mechanic to the aforementioned Windmillville, using each character's emblems to denote ownership of the hotels. The game also includes the minigame Stampede, where the player must stamp their character's emblem onto blank sheets of paper.

Emblems are featured on Goal Poles and Checkpoint Flags in more recent main series platformers, starting with New Super Mario Bros. Wii. When a character touches a Goal Pole or a Checkpoint Flag, the Bowser emblem on it will be replaced with their own, and the flag will change color to match the character as well.

Emblems also make an appearance in the Mario & Sonic series. They appear on flags and Emblems (not to be confused with the symbols themselves) in these games. The Mario characters have their usual emblems, but since all Sonic characters with the exceptions of Dr. Eggman and Eggman Nega lack unique emblems, most use silhouettes of their faces, entirely in one color besides the eyes, at a different angle and with a colored background.
