EK-X was an idea by Hellcat, as a starter boss. Later, it became EK-X instead of Elite Smasher, and more tiers were added. TK-X and MK-X were added three weeks later as an idea by Clarise. Rodrigo came up with the idea of PK-X, and then HK-X and HPK-X. Right after HPK-X, OBP-X as an idea by Gengetsu was added. Clarise secretly added OBT-X and RK-X 1 year after that.
