A word for someone who "does justice" to their (nick)name

I'm looking for an expression (preferably a single word) that denotes someone whose name or title fits them ironically too well. Names and nicknames are usually figurative, but I'm looking for idioms that I can use to make some word play in situations where they could be taken literally.

A few examples of what I want:

  • John the Headhunter took the meaning of person who does justice to their name too far. Literal murder is not part of his job description.

  • Mary "Smoking Hot" Smith, ironically doing justice to her name, did not manage to leave the building in time and was swallowed by the flames.

  • Joe "Please Don't Call Me Joe 'Joe Miller' Miller" Miller, as expected of a someone with that nickname, quit the interview after feeling improperly addressed.
    This is actually a real person.


Solution 1:

"Aptly monikered" / "Aptly monickered"

From Collins:

moniker or monicker (ˈmɒnɪkə )
noun
slang

a person's name or nickname

Your examples could scan as follows:

The aptly monickered John the Headhunter...
The aptly monickered Mary "Smoking Hot" Smith...
etc.

Solution 2:

I think the phrase you're searching for in these examples is "living up to their nickname":

John the Headhunter took the meaning of living up to his nickname too far. Literal murder is not part of his job description.

That does sound a bit off in that example. It's better to just say "lived up to":

  • John the Headhunter lived up to his nickname by committing murder on the job.

  • Mary "Smoking Hot" Smith lived up to her nickname by being swallowed up by the flames after not managing to leave the building on time.

  • Joe "Please Don't Call Me Joe 'Joe Miller' Miller" Miller, as expected, lived up to his nickname after being improperly addressed in an interview.
