Deep Navel is a contact of Veronica Stone who Crypto needs to get to Curt Calvin. Deep Navel agrees to help Crypto get to Curt Calvin, if he does a few favors for him. He has Crypto force a scientist named James Grandee to publicly admit that he believes in aliens, make a movie that glorifies aliens, and destroy $1 billion worth of property in Sunnywood.
Unfortunately, Deep Navel double-crosses him, because his favors made him Calvin's right-hand man. His fate remains unknown, for it's unclear if he perished during the attack of the Nexo Walker at the Sunnywood Bowl or if he managed to escape.
