Of the powers I've made, I'd either have
Shibito, and become a zombie but better in every way. I would live among them, teach them out ways. Mold them into the true inheritors of the earth.
Or
Deathmatch Field. At best, zombie battle royals. At worst, they wander out and have a brain aneurism. I'd blast Viking Metal to attract them toward me they cross the boundary line and go down. Boom, a whole city to myself.
Hey son, wanna' learn how ta' make witch balls?
