Peculiar
Peculiar works when you mean unusual or distinctive, sometimes with a mildly odd connotation.
Example: There was a peculiar smell in the corridor.
Outlandish
Outlandish works when you mean strikingly strange, unconventional, or implausible.

Choosing the Best Antonym for “Normal”
Unusual and atypical are the safest neutral opposites. Abnormal is common in technical contexts but can sound loaded when applied to people. Irregular and anomalous are useful for patterns and data, while eccentric and unconventional focus more on behaviour or style.
