In 2011, a research boat that had been out dredging for artifacts came into port with every last member brutally murdered. Security footage from the dock shows the silhouette of something moving away from the ship once it docked.
Analysis comparing the security footage images and pictograph information about a being called “Vampira Infernalis” which NEMO received from the GW and RF transmissions show an 81% correlation. Therefore it is likely that Vampira Infernalis was on that vessel.
Several events involving the theft of chemicals and lab equipment seem to be able to be linked to her, or the many facilities on Earth she seems to be responsible for.
She is responsible for engineering the Cosmic Squids and Star Monkeys, both of which live and/or travel through space.
Vampira appears to have traits from both humans and Vampyroteuthis infernalis.
