Mitre is the title given to an Echidna spiritual leader. In Echidnaopolis politics, the Mitre holds the highest position of power in the High Council of Echidnaopolis, and under him are the High Councilors. The Lost Tribe also had a Mitre as the group leader, with the position originally held by Arakkis and passed down through the generations to Himon, Athair and Knuckles. (StH: #108, KtE: #11)

The High Council's Mitre in Knuckles' times was involved in negotiations with Dimitri in hopes of reunifying the Dark Legion and Echidnaopolis citizens. (StH: #108, #109)
