Ultramarine Name Generator

The Ultramarines are the archetypal Space Marine Chapter of Warhammer 40,000, and their names follow the culture of their homeworld Macragge and the wider realm of Ultramar. Games Workshop leans heavily on classical Rome and Greece here: Marneus Calgar, Cato Sicarius, Uriel Ventris, Varro Tigurius and Torias Telion all read like senators, legates or philosophers. Most Ultramarines carry a two-part name of a Latin-style personal name (Titus, Cassius, Decimus, Lucian) followed by a family or cognomen-style surname (Ventris, Agemman, Vorolanus, Thiel).

A convincing Ultramarine name balances gravitas with a slight sci-fi twist. Straight historical Roman names work, but the Chapter's best names bend them a little: Sicarius rather than Sicarus, Ventanus rather than Ventidius, Chronus rather than Cronus. Rank prefixes are also part of the flavor. On the tabletop and in Black Library novels, marines are addressed as Brother, Sergeant, Lieutenant, Captain, Chaplain, Librarian, Apothecary or Ancient, and Primaris marines from Cawl's Ultima Founding share the same Macraggian conventions.

This generator mixes canon-flavored names with new ones built on the same rules, so you can name an entire company without repeating yourself. Use bare two-part names for your squad roster, and add ranks for the characters that lead them.
