Beowulf and Grendel (England). Danish monster gets killed by Beowulf who then slaughters it's grief-stricken mother. Beowolf gets killed by a dragon.
Blodeuwedd (Wales) Man cursed by mother to have no wife. Nice wizards make a woman out of flowers for him. She betrays him and is punished by being turned into an owl each night.
Selkie (Scotland) kinda like a bad mermaid but they transform from human into seals by slipping in and out of seal skin. Like to eat people but easily recognised because they look exactly like seals.
Piskies (Cornwall, we'll class it as a country out of politeness). Little mischievous people who play pranks on travellers but occasionally help out.
Fionn mac Cumhaill (Ireland). Warrior Giant with a magical thumb of knowledge. Builds a causeway to Scotland so he can have fisticuffs with another giant.
