The form of Giga Taifu Shiba-i Sazabi when he obtains the "Ultimate Darkness", as written in the G Records, by assimilating Shuu Gundam's soul. In the manga version, he calls himself "The Phoenix that lights the Heavens". Besides his normal strategist mode, he can change to the Purgatory Phoenix mode.
The true motive of Shiba-i is to become God himself and recreate a new world but he was stopped by Koumei (Kong Ming) and ultimately destroyed.
Notes & Trivia
- He is based on the MSN-04II Nightingale from Mobile Suit Gundam: Char's Counterattack - Beltorchika's Children.
- The Purgatory Phoenix mode has the design motif of the Nightingale, the chest armor design has the motif of Yami Koutei, an enemy character from the SD Sengokuden series. Up until now, there's no direct relationship between Shiba-i and Yami Koutei, and the design is thought of as fan-service.
- With Ankoku Gyokuji Psyco Gundam's legs and Kakuka Virsago's armor, Shiba-i can achieve the final mode, Shuu Masou mode. However, this form was never shown in the story, thus details are not known.
