User blog:Jaredthefox92/Should I change Grief's power?

Recently I have decided to make a version of Grief who is differnt. This means different backstory, history, ect. However, I'm wondering if I should try something else. Should I change him to where he forgoes his self-magnification powers for normal super strength or physical invulnerability? I mean personally to me it won't feel like Grief, but is the whole size changing power kind of lame?
