Leif Erikson

The Leif Erikson is the name of the golden submarine designed and captained by Hagbard Celine. It serves as the mobile headquarters of the Legion of Dynamic Discord.

The name  of the submarine alludes to a norwegian seafarer; the first european to discover north america.

The colour of the submarine invokes The Beatles film The Yellow Submarine.

It could also be a reference to the firmament; the Biblical idea that God created the Earth with waters above and waters below, thus it's enclosed like a bathysphere.
