Napoleon sums up Nietzsche's whole project;

"Napoleon, who saw something of a personal enemy in 'modern ideas' and in civilisation itself, proved through this enmity to be one of the great continuators of the Renaissance: he brought back a whole piece. a block of granite, perhaps the decisive one, of antiquity's essence.
And who knows whether this piece of antiquity's essence will finally again become master of the Nationalist movement, and whether it must not make itself the heir and protractor in an AFFIRMATIVE sense of Napoleon - who wanted One Europe, as is known, and wanted it as MISTRESS of the EARTH ..."
[Joyful Wisdom, 362 (1882)]

With Nietzsche's next book, Thus Spake Zarathustra, NAP is not mentioned by name of course, as it is an ahistorical book; however, the Type of NAP is reflected in Zarathsutra and the proposed "Zarathsutra Reich of a Thousand Years".

Nietzsche's notebooks during the period of writing TSZ make many references to NAP;

"Such men as Napoleon must come again and again and confirm the belief in the autocracy of the individual".
[WP 1026 (1883)]

This is remarkable and relates to the central doctrine of TSZ which is of course the Eternal Recurrence of the Same: the type of NAP will come again and again.

"Whoever can command finds those who MUST obey: I am thinking, e.g., of Napoleon and Bismarck..."
[WP 129 (1884)]

That such a commanding figure must needs have an aquiescent populace as found in 'democracry' and liberalism.

The following note is priceless;

"My precursors:
Schopenhauer ...
Then: the ideal artists, that after-product of the Napoleonic movement.
Then: the higher Europeans, predecessors of Great Politics.
Then: the Greeks and their origin ...[...]... The Dionysian".
[WP 463 (1885)]

I take this to be chronological. From the Schopenhauerian period to the Napoleonic, then ti the Fascist and on to the Dionysian.
