I tried to recreate it using the Revive Mk-II.

The "Armored Gundam Mk-II" is a variation of the Gundam Mk-II that was featured in a magazine nearly a quarter of a century ago.

The "Full Armor Gundam Mk-II," a full-armor version of the Gundam Mk-II, was developed by the AEUG after they stole the Gundam Mk-II. It seems to have been created with the concept that the Titans, the original manufacturer, might have also had a full-armor plan. It's not an official mobile suit, as it was only featured in a magazine, but it is listed as a variation of the Gundam Mk-II on wikis and other sites.
