There’s a kids’ anime about soccer that has a surprisingly decent Quetzalcoatlus character.
He’s called Tochan (meaning “Dad,” as he’s a human character’s adoptive parent) and… well, look at him! Plantigrade feet, stands on all fours, not a bat wing in sight. He even has visible pteroid bones with propatagia. (The pteroid is the little knob that sticks out partway down each arm, and the propatagium is the flight membrane attached to the pteroid.) 'Course, I have no idea how this thing is able to play soccer, but that’s beside the point.
Ain’t he cute?
