Some of my stand ideas that I’m having difficulty choosing between:

Be Somebody - traditional high power high speed close range punch ghost that creates holes. 

Night Prowler - object bound stand, a large sledgehammer that creates building and structure components on impact. 

Alive - wearable armor stand that forces the user and its victims to stay alive through any injury by circumventing the injury without actually healing it (or broken bones are forced into place without fixing fractures, blood loss is made up for by making more blood instead of closing wounds, neural pathways are rewired instead of fixing lost brain matter, etc.). 

Enter Sandman - automatic stand the user isn’t even aware of, manifests while user is asleep to protect them from anything it defines as a “threat” (with a very loose definition of what constitutes a threat). 

Prisoner of My Eye - close range power stand, uses molecular teleportation (deconstruct objects atomically and reconstruct them elsewhere).

Walk the Line - transports user and objects at super speeds but only along lines on a larger body (street lines, cracks in pavement, grid lines between bricks, etc). 

Rag Doll - manipulates all solid matter as though it were cloth.

As you can see, I make a lot of stands that I enjoy. XD I have many many more, but these are the ones that tickle my fancy for a RP setting.
