misshapen

This term carries a strong visual connotation of distortion and often implies a sense of wrongness or abnormality. It is frequently used in medical or biological contexts to describe physical deformities, but it can also describe inanimate objects that have been warped by heat, pressure, or poor craftsmanship.

While "deformed" is a close synonym, "misshapen" often focuses more on the specific geometry or proportions of the object rather than the process of deformation. It is generally more descriptive and slightly less clinical than "malformed," though it still retains a negative or unsettling aesthetic quality.
