Momo's powers are retardedly broken and she doesn't even think about using them that way. She can generate ANYTHING, but lets pretend it's limited to solids, she should have some basic fucking ability to launch elemental attacks like earth, water, ice, mud etc. FFS she could pull a Kimimaro and create bone projectiles and armor. Hell I don't get why she wouldn't do that to create a suit of armor every time she fights instead of using a single shield one time against Tokoyami. Instead she and most of the other girls are becoming useless and all you seen is fanfiction after fanfiction masturbating itself to how rich and nice she is, reminiscent of lazy Naru-Hina fanfiction back in the day.
Also as a side note, her powers let her build a cannon in seconds, she could quite literally help people by providing bandages, casts and a ton of resources for low cost and therefore aid people and society a lot better than by fighting villains with near non-existent offensive capabilities. Support-roles are extremely important IRL.
