Superman

Superman started as just a super man: With the amazing ability to jump over cars. And lift them too.

He travelled quickly by taking big leaps. Boinging to where he wanted to get to.

The first radio episodes changed this: Travelling with a boinging sound effect is just too silly. That is when Superman gained super human flight.

Then Superman started wooshing around.
Because of the limitations of a medium super man had to become super human.
