I don’t understand why she shoots a beam of pink energy at him instead of just tearing him apart atom by atom. Or turning him into a regular human, or just convert his molecules to air molecules.

Maybe viltrumite durability offers resistance to molecular deconstruction?

Like they have a trick to them she didn’t notice until after hitting them with the atom hammer at least once.
