Is there illuminati symbols in Mario games?

Extremely doubtful, as the real Illuminati broke up in 1785.

Since then, the Illuminati group has been fictional. It exists only in the imagination of conspiracy theorists. It is a sort of strawman or scapegoat organization. Anyone the Conspiracy Theorists dislike or envy, they declare, on no evidence of course, that they are in the Illuminati. No one has ever, in modern times, been proven to be an Illuminatus in a court of law.

The Illuminati allowed Masons to join. That has lead to confusion, as some people think it was a Masonic organization, that Masonic signs are Illuminati signs, and that since Masons still exist, Illuminati do.

Perhaps there are Masonic signs in Mario games, but Masonic does not mean Illuminatic.
