>>49833489>Spain is traditionally Catholic, and because of that, it's not like we have a very distinct mythology like maybe Greece wouldnot on the level of the greeks, but up north where there was little conquista/reconquista influence spanish myths do follow some themes depending on region, and bleed out into surrounding regions.
Catalonia's got plenty myths about demons and deals with the devil, enough that you can recognize demons for being "three-legged", even if metaphorically (eg: bipeds using canes, quadrupeds having a lame leg)
Aragon's all about giants and moras (not to be confused with moors!). The cantabrian coast on one hand shares celtic, forest inspired myths with plenty fae and elf-likes like xanas, trasgus and duendes, some critters like oricuerno, ramidreju and monuca, and some giants like basajaun, cuegle and ojáncanu. On the other hand, it shares some tangentially christian myths like meigas, akelarres, caballucos del diablo, and the santa compaña. The few specifically galician myths I know about revolve around water, like the Urco or the golden clip crayfish.
Seeing a couple three legged demon inspired fire types in Catalonia would be neat, as would stone based giant or two in Aragon. Cantabrian coast should get a horse-dragonfly hybrid for caballucos, and maybe some fairy and grass types, while galicia gets a couple water types like the urco and crayfish.
