Being Sonic's almost polar opposite personality-wise, Gloom is, bluntly put, a brooding loner. She usually acts with a cool and businesslike indifference, only occasionally showing his vulnerable side. She is rarely seen with others for an extended period of time and usually distances herself from essentially everyone. She is usually blunt and does not speak much, but she always knows exactly what to say in combat. However, Gloom never bluffs.
