I have always been a fan of being able to morph like the T-1000 meets sandman but with glass. Why glass? Well if I ever want to break into a house I can just morph through the window. Broken phone screen? Fixed! I could hide my powers and fix broken windows for a living with little to no cost to me so 100% profit. I could make myself bigger if I wanted by obsorbing more glass or smaller by the reverse method like sandman. Oh no I got discovered! What will I do? What about a new face like the T-1000 and be anyone you want! Need to hide? Jump in water and make yourself clear glass! Sounds very overpowered but it does have its drawbacks. Glass can be weak and break eazier than something like metal or wood. Not all glass is the same so there could be problems absorbing or fixing glass. If my eyes are clear I probably couldn't see too well.
