As probably terrifying as it would be, I kinda wish some mythical beasts were real. I'm sure dragons would be horrible, and I'll take a total pass on jikininki (seriously, look them up) but how cool would it be to have a very rare griffin spotting? Obviously a face to face encounter would probably be full of suck, but from a distance I bet they'd be magnificent. I mean, just look at this one by builder d' Qiu Brick, stunning!
