The letter Q only has one

[GamerInGeorgia]

Q (named cue /kju/[1]) is the 17th letter of the modern English alphabet and the ISO basic Latin alphabet. In nearly all languages using the Latin script it is a consonant, not a vowel.

A nova (plural novae or novas) or classical nova (CN or plural CNe) is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star, that slowly fades over several weeks or many months. Novae involve an interaction between two stars that cause the flareup that is perceived as a new entity that is much brighter than the stars involved.

Aha! So you are the seventeenth letter of the alphabet used by new stars! (Or just a nova classified as 'Q'.) If so, then of course the letter Q only has one member.
But one question remains: If you are Q, where is your U? Isn't Q always followed by a U? There are only two members whose name start with a U. So, is it UltLuigi? Or UubrmanX? Choose wisely @Q-Nova... take your time...
