A character called Adelbert Steiner from the videogame Final Fantasy IX. He is Captain of the Knights of Pluto and goes around shouting a lot. Nevertheless or perhaps by consequence he has a small cult following consisting of those who believe him to be God.

There are many other Steiners. Bear in mind that all of them are named after the almighty and omnipotent Adelbert Steiner. These include some wrestlers and some philosopher guy.
