DNA, Yes... but in the anime, Iris loves dragons, and she's a young girl.
I guess to me, the dragons look cute. They don't look so mean to me.
(I posted in a thread that I was scared of the dark, but not scared of false spooks or scary books. And when I went to my school's haunted house, along with some girls, they were terrified, but me? I just laughed.
