It’s entirely possible I’m missing/misunderstanding something, but I was frustrated by most of the fights in the special in relation to Samantha’s powers. I was under the impression her only limitations in atom manipulation were against people and animals. So why bother forming shields or blocking attacks when you could just directly change the gun/bullets or dangerous object into air or powder or something. Kill Cannon appears to be mostly mechanical – turn everything not flesh into sticky glue. The fight against her siblings they start fusing concrete and metal to attack with, turn that into jelly (I think she only did this once with the tire->parachute conversion). Same with cutting cars in half or dodging them, just directly transform them into something not dangerous. That’s just from a defensive standpoint, could argue the inverse as well; like can she play “the floor is lava” on enemies instead of throwing punches? Or convert oxygen to mustard gas in a targeted area etc.
