The Upside Down, 1986
Kas. He has been trapped in the Upside Down since it opened. The Upside down corrupted him and made him forget pretty much everything about the other world. He forgot his name too, so he called himself Kas. He was turned into a vampire after a few Demobats infected him. About a week ago, new portals opened up, didn’t take long for the vampire to notice.
He stalked the group that came out of the portal, who were, Steve Harrington, Robin Buckley, Nancy Wheeler and Eddie Munson. The vampire stalked them, even when they were trying to kill Vecna. But his interest was on the metalhead boy Eddie. He watched as the group left to kill Vecna.. Eddie and another kid who was named Dustin distracted the Demobats.
And soon after he sees the metalhead boy use himself as a distraction, and Kas immediately jumped into action after the bats attacked the boy. He took Eddie to a safer place and patched him up while he slept. A day later Eddie finally woke up. He looked around at the dark room and locked eyes with the vampire’s glowing ones. “Jesus Christ!” Eddie was alarmed and fell off the bed he was resting in.
