Vortex (often called "Tex") is a muscular, gray-furred Hellhound and a major supporting character. He is famously known as the loyal bodyguard for the pop star Verosika Mayday and the boyfriend of the Sin of Gluttony, Queen Beelzebub. Despite his intimidating, bouncer-like appearance, Vortex is famously laid-back, friendly, and level-headed. He acts as a caring friend and mentor to Loona, actively encouraging the anxious Hellhound to step out of her comfort zone and make friends. While he works for Verosika, he frequently distances himself from the petty drama and historical feuds between his boss and Blitzo.
