This page includes the dragon species that are titanic in size, much larger than larger dragons and putting them on a whole different level than other organisms, or even dragons. Their populations are relatively small, but singular specimens are capable of affecting ecosystem (literally create a local ecosystems so-called nests) or even landscapes dramatically, including human societies. Understandably, they are some of the largest organisms to ever existed. Like whales, all of these dragons are oceanic, marine animals; Tidal Class (though the Red Death which is now in Stoker Class had been considered as a Tidal Class dragon until very recently). It is unclear that how large they can grow up to maximally.
