I NEVER SAID HE WAS WRONG.
And if you cant get it thought your tiny closed mind, i can lock this thread. I really don't understand how you don't understand that they WERE, note the damn word WERE, as in a long time ago, the same creature. Things change over time. All the links you posted are nothing new to me. They all talk of the creature from around before the dark ages. After the dark ages the cockatrice became its own creature. On the coat of arms that has a cock/dragon is call a cockatrice. Not a basilisk. Im sorry but for some reason you dont like change. Or maybe youre a time traveler from the Ancient Greece and doesnt know that now, no one in the world calls them the same creature. Also by your same logic a Griffn, Cockatrice, Scylla, Manticore and every other creature thats made up of more than 1 creature should be called a Chimera. Cause A LONG TIME AGO the word chimera was what you called a creature that was the parts of more than one creature. Also ALONG TIME AGO the Pegasus was only one creature and its name was Pegasus but LATER IN TIME it turned into a race of winged horses, even thoguh there never was a race of them. Heres another one, A LONG TIME AGO the devil was depicted as having alabaster skin and 6 wings but NOW DAYS people see him as having horns and goat feet. Also the Greek Kraken and Norse Kraken are 2 totally different creatures but with the same name, but people still understand they arent the same creature. Why is this stuff hard for you? Not once in my life have i ever played a game, watched a show, read a present day book, read a comic or anything else where they still call them the same creature. Plus everyone else understands this. Other people already said they are 2 different creatures. It really seems you are the only person in the world that hasnt mover on and know they are 2 differnt creatures. I mean there are some many creature that come from another that shared the same name but later got its own name. Here let me tell you how it works, The story started with it being a snake (basilisk) they made up the idea that a weasel and a rooster could easliy kill it. WelL When ever people would travel they would bring a rooster or weasel with them to fight off a basilisk.( cause in real like weasels and roosted kill snakes all the time)well over time the basilsik idea started to change like most myths. It became more rooster like( more than likely when the myth spread around it got misinterpited which happens alot with myths) So it cam mostly rooster and at some point they stateded calling it COCKATRICE. Seeing how its mostly a cock. Theres also a version of the Basilisk thats a cobra,but no one cares about that version. After it stated being used on Medieval heraldry they started calling it a cockatrice. So not they are 2 different creatures. Like a said at million other points, they WERE the same creature but NOT anymore.
Heres something i copy and pasted. I didnt change the text at all.
The cockatrice was originally described as taking the form of the basilisk, but by the 1400's the name had morphed from basilisk to basilicok to cockatrice, helped by a mention in Chaucer's Canterbury Tales. This is probably where it picked up the partial attributes of a Cock, and became a different creature. In the same manner, the Basilisk originally referred to a small snake with a crest on its head (like a crown, hence the title "king") Of course, as time went on and the stories got more exaggerated, the snake got bigger and deadlier. In the Middle Ages, legends told that the basilisk could only be killed by a weasel or a cockerel, and many travelers carried these other animals in case they encountered a basilisk.
(NOTE how they use the words different creature)
And finally I will say the last on this(which i hope is)
The Basilisk- is a greek myth which it is a snake that can turn people to stone.Also Basilisk means "King of Snakes". The greeks had lots of myths on snakes.
Cockatrice-Medieval times, Changed into the cock form. But had the same power as the Basilisk.
Destructor- After thinking, the snake version would work better in the main story because of its time period. Since its more around greek times and thats where the snake basilisk started. So i could use you snake version in the main story and the Cockatrice one in the Dark Ages story. It would make more sense history wise.But keep the good ideas coming.
