The Legio Ultima is a Loyalist Titan Legion of the Collegia Titanica, one of the military arms of the Adeptus Mechanicus.

There is a distinct possibility that this Legion may be one of two classified Titan Legions that personally serve the Fabricator-General of the Adeptus Mechanicus on Mars. The Legion's current status remains unknown.
