I want to write a character with necromancer abilities and I'm struggling to find ideas on how to make him unique! Basically, the character in question is lazy. He always just chills in hoodies and never contributes much to any fights in the story. However, I want him to actually have this amazing necromancer power that he never really uses, until he learns bla bla bla story stuff. What I'm focusing on here is the power itself.

How do I make it unique? The basic idea is: He can make the dead obey him and give them sort of a new consciousness. I LOVE the idea of them being literal shadows, but Solo Leveling did that and I hate to be unoriginal. Ideas?
