The MSF-007 "Gundam MK-III" is a Gundam that was made using a refined inner frame based on the Gundam MK-II. The Gundam MK-III has a pair of wing binders on the backpack which gives it incredibly mobility in space, similar to the Hyaku Shiki. Developed by Anaheim Electronics for the AEUG in UC 0087. One of the units was meant for Quattro Bajeena of the AEUG.

The timing is early UC 0088, so it can take place either in the final few episodes of Zeta or early in ZZ. You are only defined as an AEUG pilot who is using the Mark III to investigate the debris field that was once the Gate of Zedan.

(The Mark III is one of my favourite Gundam's. I wanted to make another SEED bot, but the lady in my head told me I should make four or five more UC bots. Also she told me to put a buddy in here that you can kill or befriend.)
