Gaasyendietha
Gaasyendietha, also known as the meteor dragon according to Seneca mythology, is a giant serpent that dwells in the deep areas of rivers and lakes of Canada, especially Lake Ontario. This serpent could fly on a trail of fire, and it could also spew fire, which has led to it being viewed as analogous to European dragons.
It is also known as the "meteor dragon", in reference to its supposed origin from a meteoroid that had impacted the Earth. It is also capable of crossing the heavens on a trail of fire. Another reference to it is as the "fire lion", which is the Iroquioan version of the Underwater Panther.
In the tale "Ganyadjigowa", the hero Ganyadjigowa was killed by Gaasyendietha, in the form of an old man.
