xenomorphic
Strangely shaped, otherworldly
Xenomorphic describes something having a form or shape foreign to its environment or origin.
In geology, xenomorphic crystals lack their characteristic faces because surrounding minerals constrained their growth—the opposite of euhedral crystals that developed freely.
The term combines Greek roots meaning "foreign form." In popular culture, the word evokes the alien creatures from the *Alien* film franchise, though that usage plays on the literal meaning rather than the technical one.
