Since she can apparently turn anything into anything (as long as it’s not human/animal matter), why doesn’t she immediately turn all her enemies’ equipment into sand?
The Flaxans’ guns? Sand. Killcannon’s kill-cannon? Sand. Doc Seismic’s gauntlets? Sand.
She can apparently manipulate matter attached to her own person (e.g. changing her outfit), so why not others’?
Is there an in-universe reason for this, or is it a writing issue?
Power of plot.
A superhero’s power in any given fight is exactly at the levels the authors need it for their current narative.
It doesn’t matter what the hero was capable of just one scene earlier or after.
Also 99.9% of the authors don’t understand the physics involved in feats that are just added because they’re cool and the implications these should have (but just don’t)
