Secrets

Unlockable	Condition to Unlock
Giant Karakuri Raijin-Oh	On Sub Scenario 9, allow Raijin-Oh to be destroyed. The kids will redeploy in Giant Karakuri Raijin-Oh at the top left of the map. When you get the Raijin-Oh Team permanently, it will come with them. It might be something you have to do in a first playthrough of the sub scenario (untested). This secret is NOT in XO.
Aina Sahalin Extra Apsalus 2	In Sub Scenario 15, you must convince Aina with Shiro BEFORE destroying the Zanzibar. You will obtain an extra Apsalus 2 afterwards. In Scenario 20, Aina will then join. It might be something you have to do in a first playthrough of the sub scenario (untested). Aina might not be a secret (untested).
Bernard "Bernie" Wiseman Extra Zaku II	In Sub Scenario 17, destroy the Arms, Legs, and Head of Bernie's unit. You will obtain an extra Zaku II (NOT a Zaku II Kai) and Bernie after the stage. It might be something you have to do in a first playthrough of the sub scenario (untested).
Extra Bat-Shu	In Sub Scenario 21, complete the stage in 7 turns to obtain an extra Bat-Shu. This might be something you have to do in a first playthrough of the sub scenario (untested).
Fa Yuiry and a Ground Type GM	Complete Sub Scenario 29.
Jack King & Mary King in Texas Mack	Complete Sub Scenario 32. Note that he will join you temporarily anyway for Mission 2.
Venus A	Complete Sub Scenario 33. Aphrodite A will turn into this.

Four Murasame and Re-GZ	Complete Sub Scenario 34.

Full Armor Gundam (Frame)	Complete Sub Scenario 38. This can then be equipped on the RX-78-2 Gundam as a frame in the intermission menu.

Puru 2 and Qubeley Mk-2 (Puru 2 Custom)	Fight Puru 2 with Puru in Stage 41, then fight her with Judau twice. Judau must then destroy Puru 2 (this can be during the second battle encounter).
