User blog:Betwixt/Here Be Monsters?

I had an idea to populate the Villains Lore with some giant monsters straight from legend - I got inspired by the fact we have the Hyborean Age as a time when elder-gods and demons roamed Earth.. so I thought what if some large monsters from that era escaped the fate of the others and continued to survive in the Earth's oceans?

here are some of the monsters I feel would be good additions in stories: some of these could also be "pets" to the Fomori or other sea-dwelling creatures.. I don't think Earth's oceans in Villains Lore has too many inhabitants yet.. so what do you guys think on the idea to populate it a suitable manner for Villains?
 * Aspidochelone (gigantic sapient sea-turtle)
 * Fastitocalon (gigantic shark)
 * Jasconius (gigantic sapient fish)
 * Lyngbakr (gigantic eel)
 * Hafgufa (gigantic sea-serpent)
 * Tannin (sea-dragon)
