Hates his brother, Ignis Battler, since he always tells him to not lower the thermostat. Always tells his brother not to play with fire. Also wants to solve global warming, but his brother is preventing him from doing so. Comes off as really cold, quite literally, and usually acts uneasy or really tired. Pretty soft-spoken, contrary to his brother. Pauses a lot in his sentences with ellipses since he's cold. Dependable and supportive. Loves snow and the cold. Hates fire, heat and chaos.
