Rapidash: Sagesse; it literally means "wisdom" in French.
Wartortle: Azaril; taken from the Arabic "azraq" (blue) and "hostile".
Rhydon: Acieton; derives from "acier" (steel), named after its grey coat, and "ton", which is obviously the weight factor
Pidgeot: Altair definitely; it literally means the "diving eagle" in Arabic.
Luxray: Namir; it means "tiger" in Arabic, like the skitty in my fanfiction.
Tauros: Fierun (Fear-roon); it derives from "asmarun" (brown) and "fierté" (pride)
Kinda got stuck with Rhydon and Tauros rofl They're not very good :s as said, I usually just name mine colours!
