June

This 10-year-old girl may look cute, but she is truly a force of blazing fire. Being an inverted Kindness soul, June has access to a unique trait known as Hostility, and her personality reflects this.

Personality
She is shown to care little for any of her foster siblings’ antics. She also has a short temper lashing out at anyone who tries to bug her. Despite her disinterests, she still has compassion for her older blood sister, Janice, cats, and her foster parents (Toriel and Asgore). She can use her anger to advantage as she can use her “kindness” fire magic to light up her opponents with green flames. She also faces extreme adversity since she lost her parents long ago she has felt lost and hopeless and feels that she can experience normal relationships of a family. However, despite this, her foster family helps her through her troubles, and no matter how grumpy she may look. She is very kindish.
