The Koopa Troop appears in the Pathverse, as the inhabitants of the Koopa Kingdom. The Koopa Kingdom was formed in the First Age, as the Koopa's did not want to be a part of the Devotee kingdom. The Koopa Kingdom remained mostly isolated throughout the rest of the ages, occasionally trading with the other nations until the Fifth Age, when King Bowser launched an attack on Devotee Castle and successfully claimed control of the Devotee kingdom.
