Ludomon

ルドモン

One of the 'Legend-Arms', who are capable of transforming themselves into weapons. It is the only one among the 'Legend-Arms' capable of transforming itself into a shield. It wields sturdy, steel shields on its head and on both arms, protecting it from attacks coming from any direction. As a Digimon made with protection in mind, there have been records of it protecting areas being targeted by the D-Brigade. (Source: Wikimon)
