Echelon is a Matoran who served as Irrie's deputy during the Dust Realm War.
Echelon was originally a citizen of one of the five states that remained after the imperial advances of the United League were halted. Once the five states joined together to form the Partisan Coalition, he enlisted in the Partisans' Army.
100 years ago, he fought in the Battle of Negotino. He was one of the survivors of the King Cannon's malfunction, which killed two-thirds of all the Matoran present. He continued to serve under the Partisans afterward.
30 years ago, after Irrie defected from the Guerrillas to the Partisans, Echelon was reassigned by the Partisan High Command to serve as his deputy. He continues to hold that position to this day.
