Demon Core is an amicable individual who enjoys the company of others, offering to help others where he can. He is judged for him being an incredibly deadly object, and is thus often excluded from interacting with his peers, being seen as an obstacle rather than a person. He appreciates the company of people who accept him, being eager to help Cane's Cup and Hives and finding solace in the company of Dont, a fellow excluded entity. He never uses his deadliness to force others to do his bidding.
