4)Rosso Aegis
Pretty straightforward one, it has the same Aegis weapons minus the vulcans, and can optionally carry two Beam Rifles, either hand carried or fixed to the forearms according to the scratchbuild pictures from Phantom Pain Report(there's a mode that uses this configuration in particular, with the extra arms as support); no shield. It can use the Scylla in MS mode, can bend it like Forbidden thanks to the new arms structures(?) and the manga shows the beam cannon can fire spreading shots like a shotgun. What are the multiple forms actual names?

The second most unorthodox MS in this story. First, the Trikeros: the profile claims it only has 3 Lancer Darts, nothing else; yet you can see only 2 lancer darts and 3 exiting holes

. In the manga it only fires 2 lancer darts, then what's the point of the third hole(the bottom one)? Either there's a hidden lancer dart inside the shield or it's used for other purposes. Beam rifle/saber perhaps? Sadly without some HQ lineart with mecha designer notes we'll never know. Second, the other arm thing called Claw and 6 barrel Launcher according to the profile: the manga only shows it firing Dummy Balloons(first use in the Seed universe?) and to assume it can fire other things we again need the lineart notes or other sources; and what's the point of this other claw if it already has bigger ones on the backpack(JP wiki claims it's for melee combat and enemy capture)? Third, the backpack: as we already know these arm units can destroy even PS armor and can deflect beam at will, the only new thing is it also has a Pile Bunker as per lineart and profile description in the last scan.

The most unorthodox MS and the reason I opened this thread. According to the profile it has: Shield, Rocket Anchor, Laser Sword, Laser Rod. Let's go through each of these individually(for linear notes please use the first scan and zoom it)
a)Beam(?) Cannon: not mentioned in any profile, but used in MA mode in the manga. Is attached to a tentacle like thing and can be seen on the chest in MS mode(can it be used in MS mode?). Since all its weapons are laser based, could this also be a Laser Gun/Cannon?
b)Laser Sword: pretty simple one to figure out: stored on the shield can be detached for close combat. The shield appears to hold 3 of these(!)
c)Rocket Anchor: this one took me a while to figure out, these anchors are actually the 3 shield sections that don't store the Laser Swords. From the lineart it appears to have verniers on the back and a cable attached, it also opens to reveal a Laser(?) Saber(the laser generator looks like the Laser Sword one)
d)Laser Rod: stored in the forearms, in the manga it's somehow attached to the shield to be used as a yo-yo weapon(really wanted to see where it attaches, the lineart notes may say where but it is illegible

). The lineart notes has mount written in katakana pointing to the laser rod tip, perhaps for the shield. It doesn't look like it can be used as weapon like the GOUF one(heat, shock) and looks a lot like the tentacle beam cannon.
e)Shield: in MA mode it's clear it has Armure Lumiere capability, in MS mode the manga isn't clear(to transform it loses some pieces of armor). It has a piece of armor to attach it to the arm in MS mode. When used as yo-yo weapon it isn't clear if the laser swords are activated or it's used as a solid weapon(first option makes more sense).
Sadly the only scan I have with the lineart notes is pretty illegible, if someone has the Gundam Ace volume where GATE 09 was first published they could see if the text is legible at all. The Guard Shell is quite equipped, imagine throwing the shield then activating the rocket anchors to perform a massive area attack
