The DA-77 Powered Suit Systems are specialized defense armor that amplifies the combat power of the Dia-Nauts.

One Dia-Naut in a powered suit system can do the work of 10 Dia-Nauts. These suits are designed to incorporate the essence of the Diaclone's first powered suit and the first generation powered system. The figures also come with a pair of 1/60 Diaclone mini action figures.
