But, yeah, there are certain kinds of dragons that 'could' be real (but have no legit and believable proof), but, that doesn't stop you from making any up. With your own specifications.

Haha, I think it's funny that people are saying it was 1998 and people didn't know as much about dragons as they do now.
HELLO, they're dragons, they aren't even real! People can make anything up about dragons. A dragon can be any way somebody wants them to be, because there is no specifications, because they aren't even real!

Not necessarily.  There's a believe that dragons are or could be real.  The only limitation hindering us from dragons is the fact that no animal on earth, nor fossil has found any skeletal remains of a creature with more than 4 limbs.  This doesn't rule out the possibility for a wyvern or serpent type dragon though.

There are also creatures that give off methane gas through their bodies, so even breathing fire isn't totally impossible.  All you need for fire is fuel, oxygen, and a spark.  And since animals can manipulate their breathing valves to make grunts and various animal sounds, it is definitely possible a caliced inert could generate a spark.

And don't forget that dragons are 'mythilogical' in several cultures that for the longest times remained isolated from each  other, but they all have this physical apearance of a fire breathing lizard that sometimes has wings.

But the argument is stupid.  I once had an argument with someone about Spike from MLP not being a dragon cuz he didn't have wings...

There are different kinds of dragons and they all have very specific descriptions.

Well I think there was one in dream weabers home wolrd but me and my brother just think is a metro
