Bosch is a rude and brash witch who has no fear of insulting or humiliating those she looks down upon, without caring about the feelings of others, especially Luz and Willow. She is also very power-hungry, often giving orders to her friends. She is obsessed with Penstagram, often using it to chat with her group of friends or make fun of someone else.

Despite her unpleasant attitude towards others, she seems to really respect her friends.
