Halo Name Generator

Halo names follow strict house styles, and getting the style right matters more than the word itself. Spartan-IIs are a first name plus a three-digit tag (John-117, Kelly-087), Spartan-IIIs add a company letter (Carter-A259, Kat-B320), and Spartan-IVs keep full civilian names like Sarah Palmer. UNSC smart AIs take a single evocative name, usually borrowed from myth, legend or the stars: Cortana from Arthurian romance, Roland from the Chanson de Roland, Serina, Isabel, Araqiel, Iona and Lysithea. Dumb AIs and ship minds get plainer names such as Jerrod, Mack or Black Box, and every smart AI also carries a serial like CTN 0452-9.

Forerunner ancillas speak differently: a number followed by a two-word epithet, as in 343 Guilty Spark, 2401 Penitent Tangent and 031 Exuberant Witness, while the great contender AIs are Mendicant Bias and Offensive Bias. Covenant names carry their species in their sound. Sangheili use a short given name and an apostrophe surname (Thel 'Vadam, Jul 'Mdama), Jiralhanae take Latin-flavored single names (Tartarus, Atriox, Escharum), Unggoy have doubled syllables (Yayap, Dadab) and San'Shyuum rule as the Prophet of a virtue.

The list mixes canon characters with originals in each register, plus fireteam names, callsigns like Sierra 117 and Echo 419, and UNSC and Covenant ship names, so you can name a whole squad, an AI companion and their ship.
