Adolphus Kraus (Cataclysmic Gerosha)

Adolphus Kraus is a villain in The Gerosha Chronicles, often operating as an avatar of the mythical Germanic Christmas demon Krampus. As an Emotion Battery Marlquaanite, he can reshape reality to a limited extent based on the feelings of fear and guilt he can cause or else find present in his primary targets.

Character bio
''After gaining powers of immortality and nigh-invulnerability, 17th-century sadist predator Adolphus Kraus broke off from the Society of the Icy Finger to begin his career as a supernatural serial killer / rapist. He discovered the safest route to covering up his appalling crimes was to abide by the rules of Germanic folklore. Thus, he became an incarnation of the legend of Krampus, the Christmas Demon. While he cannot resist the occasional innocent meat, this monster knows his safest bet is to target victims that he believes won't be missed.''
