"Do you suffer anxiety attacks? Acute Paranoia? Always feel like something horrible can leap out at you at any moment? Well then, do I have a Tonic for you, friend."
Doc Penezek is one of the spirits who appears in the video game. After Zeke has captured all the shriveled souls in the kitchen with the Beacon, Doc will appear. When the player interacts with him, it's found out that he is the one who created the tonics that can replenish Zeke's bravery.
