According to the character designer, Tatsuhiko "Falcoon" Kanaoka, both Meira brothers were initially conceptualized to be the KOF counterparts to the Bogard brothers, given the game's setting, Southtown, is the same in Fatal Fury. Several of the brothers' prototype designs were assigned to other characters' alternate outfits; in this case, Alba's prototype design became Rock's alternate outfit, and Soiree's prototype design became Maxima's alternate outfit.
